The maximum number of POTS users varies according to codec standard: − Four concurrent POTS calls for G.711 and G.729. − Two concurrent POTS calls for G.726 and G.722. The EGW1520 voice services comply with the following standards:  G.711A, G.711u, G.729, G.726, and G.722  SIP (RFC 3261-3265)  SIP Session Timers (RFC 4028)  SDP (RFC 2327)  RTP/RTCP  RFC2833 UC Mode The EGW1520 is used together with the eSpace UC solution. In UC mode, the EGW1520 can be registered with multiple SIP servers at the same time. Phones connecting to the EGW1520 are registered with the SIP server on the central node at the headquarters. All calls are processed by the SIP server at the headquarters. When the EGW1520 is disconnected from the active and standby SIP servers, the EGW1520 automatically enters the local survival mode and functions as the local SIP server to accept registration of internal users. The EGW1520 processes all calls. The EGW1520 can function as the local PSTN landing gateway, implementing local incoming and outgoing calls and helping reduce toll call fees. Connecting to the PSTN Network The EGW1520 provides one FXO port used to connect to the PSTN network. An intra-office user dials the outgoing prefix and an outer-office user's number to make an outgoing call through the FXO port. An outer-office user dials the number that the PSTN carrier allocates to the FXO port to make an incoming call. The EGW1520 supports the switchboard and dedicated line functions. By default, the switchboard function is enabled.  The EGW1520 supports one FXO port.  The FXO port supports only the one-stage dialing mode.  Only one call can be made through the FXO port at a time.

eSpace EGW1520 Enterprise Gateway Product Documentation 3 Overview Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 20 Voice QoS This topic describes the voice QoS policies supported by the EGW1520. VAD Voice activity detection (VAD) is a technology used in speech coding and speech recognition where the presence or absence of human speech is detected. The VAD avoids unnecessary coding and transmission of silence packets in Voice over Internet Protocol (VoIP) applications, saving computation and network bandwidth. CNG Comfort noise generator (CNG) is used with VAD. When the VAD function is enabled and no packets are sent during the silent period, the listener may think that the call has disconnected. To avoid this, the EGW1520 enables the CNG function on the receiver end. The EGW1520 CNG technology complies with RFC3389. EC Echo cancellation (EC) is a process of removing echo from a voice communication to improve voice quality on a telephone call. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network. The EGW1520 EC technology complies with ITU-T G.168. PLC Packets are often lost on the connectionless IP network as a result of network congestion, buffer area spillover, or error codes. A packet loss compensation (PLC) algorithm is used to minimize the effects of packet loss. Lost frames can be reconstructed during decoding based on the voice context, which ensures the quality of the received voice. Jitter Buffer With the jitter buffer function enabled, received packets can be buffered and then retrieved and processed to remove jitter. Reliability The EGW1520 provides various technologies to ensure voice communication reliability. Multi-SIP Registration–DR Mechanism in a Small Branch Multi-SIP registration is a disaster recovery (DR) mechanism for emergencies, which is used to avoid SIP server breakdown. Functioning as a voice access device in small branches, the EGW1520 can register with two SIP servers at the same time. When the active SIP server is faulty, the EGW1520 switches services to the standby SIP server. When the active SIP server is recovered, the EGW1520 switches services to the active SIP server. Power-off Survival The EGW1520 provides an FXO port for power-off survival. When the EGW1520 is powered off, the POTS phone connected to the PHONE port is automatically connected to the FXO
eSpace EGW1520 Enterprise Gateway Product Documentation 3 Overview Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 21 port to access the PSTN, which allows the EGW1520 to still support basic voice services during power-off. Local Survival Functioning as a voice access device in small branches, the EGW1520 supports local survival. When the EGW1520 detects that the central node in the headquarters is disconnected from the SIP server, the EGW1520 processes local calls. 3.4.2 Data Features The EGW1520 provides rich data services to meet requirements of different users.

Specification Voice quality technologies: voice activity detection (VAD), comfort noise generator (CNG), echo cancellation (EC), packet loss compensation, and jitter buffer.  VAD The EGW1520 detects silent periods in voice signal streams, and removes data from the silent periods to conserve bandwidth resources without reducing service quality.  CNG The CNG is used with the VAD. When the VAD function is enabled and no packet is sent during the silent periods, the listener may consider that the call has been disconnected. To avoid this situation, the EGW1520 enables the CNG function on the receiver end. The CNG technology complies with RFC 3389.  EC An echo is quickly transmitted to a listener during a local call because the end-to-end delay is short, and the listener may not hear the echo. However, the end-to-end delay is long during an international call, and the EC must be enabled. The EGW1520 EC technology complies with ITU-T G.168.  Packet loss compensation Packets are often lost on the connectionless IP network as a result of network congestion, buffer overflow, or error codes. A packet loss compensation algorithm is used to minimize the effects of packet loss. Lost frames can be reconstructed during decoding based on the voice context, which ensures the quality of the received voice.  Jitter buffer With this function, received packets can be cached

If the ADSL and WAN ports are unavailable, you can insert a 3G data card to the universal serial bus (USB) port to access the 3G network. 7.2.1 ADSL The EGW1520 uses an ADSL port to connect to the upstream network. The ADSL uses high frequencies that are not used by voice phone calls and several modulation methods to achieve high-speed data transmission over twisted-pair copper phone lines. Description This topic describes the principle, implementation, specification, and limitation for the EGW1520 to connect to the upstream network by using the ADSL. Principle Using the frequency-division multiplexing (FDM) technology, the ADSL divides a regular telephone line into three separate channels for the telephone, upstream link, and downstream link. Using the discrete multi-tone (DMT) technology, the ADSL divides the frequency band from 0 kHz to 1.1 MHz on the telephone line into 256 sub frequency bands, each of which occupies a 4.3 kHz bandwidth.  4 kHz or lower: Provides traditional telephone services.  20 kHz to 138 kHz: Transmits upstream signals.  138 kHz to 1.1 MHz: Transmits downstream signals.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 75 Telephone signals are transmitted at the frequency band from 0 kHz to 4 kHz, while signals of ADSL services are transmitted at other frequency bands. ADSL in practical application are deployed as follows:  On the service provider side, connect the telephone lines that have enabled the ADSL service to a digital subscriber line access multiplexer (DSLAM).  On the user side, use an ADSL modem to connect telephone and data lines. The ADSL uses high frequency signals. To prevent noise disturbance to calls, splitters are required on the service provider side and the user side to separate data signals from audio signals. ADSL2 The ADSL2 improves the initialization state machine's performance by reducing the frame overhead. In addition, the ADSL2 uses higher modulation rate, improved coding gain, and enhanced signal processing methods. Compared with the ADSL, the ADSL2 takes advantage in rate and coverage. Its maximum downstream rate is 12 Mbit/s and maximum upstream rate is 1 Mbit/s. ADSL2+ In addition to basic ADSL2 features, the ADSL2+ extends ADSL2's downstream frequency band, which increases the downstream rate within a short distance. Two ADSL2 standards specify downstream frequency bands to 0 kHz–1.1 MHz and 0 kHz–552 kHz, while the ADSL2+ specifies the downstream frequency band to 0 kHz t–2.2 MHz. This increases the ADSL2+ downstream rate to 24 Mbit/s within 1.5 km. The ADSL2's upstream rate, depends on the line condition (basically, it is 1 Mbit/s). Implementation The EGW1520 functions as a modem on the ADSL network to modulate and demodulate ADSL signals. After being connected to a remote DSLAM, the EGW1520 connects users to the IP network.

User C sends a call request to the SIP server in at the headquarters' central node through the EGW1520. 2. The SIP server processes the request and transfers the call the IMS/NGN or PSTN network. 3. The external user picks up the phone and the call is set up. Local Survival The EGW1520 supports the local survival function. When the EGW1520 is disconnected from the primary and secondary SIP servers, it automatically switches to the local survival mode. In this mode, the EGW1520 functions as a local SIP server for internal users to register with. All calls connected to the EGW1520 are processed by the EGW1520. Outgoing calls are made through the FXO port. The EGW1520 sends heartbeat detection messages to both the active and standby servers. When either server recovers, the EGW1520 automatically disables the local survival mode. Data Synchronization In UC mode, you do not need to configure internal user numbers on the EGW1520. All user numbers are allocated and synchronized to the EGW1520 by the data synchronization server such as the BMP. Users can only view phone number information on the web page of the EGW1520. They cannot change the information. Figure 7-36 shows the typical network of data synchronization. Figure 7-36 Typical network of data synchronization
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 115 Before the configuration, collect the user quantity in a branch and apply to the enterprise IT administrator for number allocation. Then the SIP server allocates user numbers and the EGW1520 synchronizes the user numbers with the data synchronization server. The data synchronization mechanism is as follows:  The EGW1520 initiates data synchronization. The EGW1520 sends a data synchronization request to the data synchronization server when the EGW1520 restarts, data synchronization server information on the EGW1520 changes, or the EGW1520 switches from the local survival mode to another mode.  The data synchronization server initiates data synchronization. The data synchronization server regularly sends data synchronization requests to the EGW1520 to ensure user data consistency between them. Specification  A maximum of 20 SIP users.  One FXS port, connecting to one POTS user.  A maximum of 8-channel users (SIP users and POTS users) can simultaneously initiate calls. Standards supported by voice service: − G.711 A, G.711 u, G.729, G.726, and G.722 − SIP (RFC 3261–3265) − SIP Session Timers (RFC 4028) − SDP (RFC 2327) − RTP or RTCP − RFC 2833 Configuration In UC mode, all phones connected to the EGW1520 are registered with the SIP server at the headquarters. Before the configuration, apply to the enterprise IT administrator for number allocation. Prerequisite  You have logged in to the web management system. For details, see 7.7.1 Web Management.  The EGW1520 has connected to the uplink network. For details, see 7.2 Connection Modes.

Description The EGW1520 provides four FXO ports used to connect to PSTN networks, allowing voice users on the EGW1520 to communicate with PSTN users. Principle The EGW1520 provides an FXO port for connecting to the PSTN network. An external user dials the number that the PSTN carrier allocates to the FXO port to make an incoming call. An internal user dials the outgoing prefix and an external user's number to make an outgoing call through an FXO port. During an outgoing call, the EGW1520 functions as the PSTN landing gateway, implementing local outgoing calls and helping reduce toll call fees. The EGW1520 supports the switchboard, DDI, and dedicated line functions. By default, the switchboard function is enabled. Implementation for the Switchboard Figure 7-39 shows the application scenario for the switchboard.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 120 Figure 7-39 Application scenario for the switchboard The call process for the switchboard is as follows: Outgoing call 1. An internal user dials the outgoing prefix for the FXO port (for example, 0571) and the number of an external user. 2. The SIP server at the headquarters determines the location of the number based on the outgoing prefix, and sends the outgoing prefix and the external user's number to the landing gateway in the corresponding branch. 3. The landing gateway in the branch automatically queries an idle non-dedicated FXO port for the user to make the outgoing call. A non-dedicated FXO port is a port for which the dedicated line is not configured. For details about the dedicated line, see Implementation for the Dedicated Line. 4. The external user answers the call. The number that the PSTN network carrier allocates to the FXO port is displayed to the called party. 5. One party hangs up the phone to end the call. Incoming call 1. An external user dials the number that the PSTN network carrier allocates to the FXO port, that is, the switchboard number. The external user hears an announcement, for example, "Thanks for calling XX company. Please dial the extension number. To query numbers, dial 9. End the number with a pound key."
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 121 2. The external user dials an extension number (internal number of any internal user) or dials 9 (to connect to the preset attendant number) as prompted, and presses the pound key (#). If the extension number does not belong to the branch where the switchboard is located, the EGW1520 sends the number to the SIP server at the headquarters. The SIP server at the headquarters automatically queries the corresponding internal user. 3. The internal user or attendant answers the call. 4. One party hangs up the phone to end the call. Implementation for the DDI The DDI binds an internal user to an FXO port. When an external user makes an incoming call to the internal user through the FXO port, the call is directly connected to the internal user. After the DDI is configured for an FXO port, other users can still make outgoing calls through the FXO port. Figure 7-40 shows the application scenario for the DDI. Figure 7-40 Application scenario for the DDI A DDI user can be bound to an FXO port in the same branch or in another branch as shown in Figure 7-40. The call process for the DDI is as follows: Outgoing call 1. An internal user dials the outgoing prefix for the FXO port (for example, 0571) and the number of an external user.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 122 2. The SIP server at the headquarters determines the location of the number based on the outgoing prefix, and sends the outgoing prefix and the external user's number to the landing gateway in the corresponding branch. 3. The landing gateway in the branch automatically queries an idle non-dedicated FXO port for the user to make the outgoing call. A non-dedicated FXO port is a port for which the dedicated line is not configured. For details about the dedicated line, see Implementation for the Dedicated Line. 4. The external user answers the call. The number that the PSTN network carrier allocates to the FXO port is displayed to the called party. 5. One party hangs up the phone to end the call. Incoming call 1. An external user dials the number that the PSTN network carrier allocates to the FXO port. 2. The phone of the DDI user bound to the FXO port (for example, internal user 1 in Figure 7-40) rings. 3. The DDI user answers the call. 4. One party hangs up the phone to end the call. Implementation for the Dedicated Line The dedicated line binds an internal user to an FXO port and sets the FXO port to be a dedicated port. When an external user makes an incoming call to the internal user through the FXO port, the call is directly connected to the internal user. Only the internal user can use the FXO port to make outgoing calls. Figure 7-41 shows the application scenario for the dedicated line.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 123 Figure 7-41 Application scenario for the dedicated line A dedicated user can be bound an FXO port in the same branch or in another branch as shown in Figure 7-41. The call process for the dedicated line is as follows: Outgoing call  If the external user and the FXO port that the dedicated user is bound to are not in the same branch, the call process is similar to that for the switchboard. For details, see Flow of Outgoing Calls Through the Switchboard.  If the external user and the FXO port that the dedicated user is bound to are in the same branch, the call process is as follows: 1. A dedicated user (for example, internal user 1 in Figure 7-41) dials the FXO outgoing prefix (configurable, for example, 0) and an external user's number. 2. The SIP server at the headquarters sends the outgoing prefix and the external user's number to the landing gateway in the branch where the FXO port bound to the dedicated user is located. 3. The EGW1520 automatically queries the FXO port bound to the user for the user to make the outgoing call. If the bound FXO port is unavailable (for example, no phone line is connected to the FXO port), the EGW1520 automatically queries a non-dedicated idle FXO port for the user to make the outgoing call. 4. The external user answers the call. The number that the PSTN network carrier allocates to the FXO port is displayed to the called party. 5. One party hangs up the phone to end the call. Incoming call

The phone of the dedicated user bound to the FXO port (for example, internal user 1 in Figure 7-41) rings. 3. The dedicated user answers the call. 4. One party hangs up the phone to end the call. Specification Four FXO ports.. Limitation  The FXO port supports only the one-stage dialing mode.  Each FXO port allows one user to make an outgoing or incoming call through the FXO port at the same time. Configuring an Outgoing Prefix This topic describes how to configure an outgoing prefix for the FXO port on the EGW1520. After the outgoing prefix is configured, an intra-office user can dial the outgoing prefix and the number of an outer-office user to make an outgoing call through the FXO port. Prerequisite You have logged in to the web management system. For details, see 7.7.1 Web Management. Principle The outgoing call prefix must match the outgoing call prefix configured on the SIP server at the central node. Based on whether the SIP server at the center node deletes the outgoing prefix, the outgoing prefix configuration is classified into the following modes. For details about the configuration modes, contact the IT administrator at the enterprise headquarters.  The SIP server at the central node does not delete the outgoing prefix. Configure an outgoing prefix (such as 0571) for each branch to identify the area where a branch is located. The outgoing prefix for each branch must be unique. For example, the outgoing prefixes of branch A and branch B are 0571 and 0755 respectively. If user D dials 057112345678, the SIP server at the headquarters determines that the number belongs to branch A according to the prefix and sends the number 057112345678 to the EGW1520 at branch A.  The SIP server at the central node deletes the outgoing prefix. Configure at least two outgoing prefixes for each branch. One prefix identifies the area where the branch is located and the other prefix is the same as a prefix on the SIP server at the central node. For example, the outgoing prefixes of branch A are 0571 and 0. When user D dials 057112345678, the SIP server at the headquarters receives the number, deletes the prefix 0571, adds the new prefix 0, and sends the new number 012345678 to the EGW1520 at branch A. Procedure Step 1 On the web management system, choose Voice > FXO Configuration.

An intra-office user can dial the outgoing prefix to make an outgoing call through the FXO port. For details, see Description. NOTE  A maximum of 16 outgoing prefixes can be configured for the FXO port on the EGW1520.  The outgoing prefix must not conflict with internal numbers and emergency numbers. Once an outgoing prefix plus an outer-office number are the same as an internal number, the call will fail to be made towards the outer-office user. Instead, the internal user is connected. Property  Remove: The outgoing prefix is deleted for outgoing calls.  Retain: The outgoing prefix is not deleted for outgoing calls. This mode is applicable to the situation where the outgoing prefix is the same as the first digit in the outer-office number.

When the EGW1520 is powered off, the analog phone connected to the PHONE port can be connected to the PSTN through the FXO1 port. Principle and Implementation When the EGW1520 is powered off, the PHONE port automatically connects to the FXO1 port. Generally, the EGW1520 power-off survival function is available once the cables are connected. You do not need to configure the function on the web management system. The cables are connected as follows:  The FXO1 port on the EGW1520 has been connected to the PSTN.  An analog phone has been connected to the PHONE port on the EGW1520. When the EGW1520 is powered off, it automatically connects the analog phone connected to the PHONE port to the PSTN, as shown in Figure 7-46. Figure 7-46 Power-off survival
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 131  When the power-off survival function is enabled, the number of the analog phone connected to the PHONE port changes from the external number to the FXO1 port number, and the dialing rule changes from the EGW1520 dialing rule to the PSTN dialing rule.  After the power-off survival function is enabled, the ongoing call does not end after the EGW1520 powers on again, but the voice services cannot be used until the call ends.  After the power-off survival function is enabled, the FXO switchboard, DDI, and dedicated line functions cannot be used. To verify that the power-off survival function is enabled, perform the following steps: 1. Cut the power supply of the EGW1520. 2. Use an analog phone that is connected to the PHONE port to call an external number. If the call is connected, the power-off survival function is enabled. If the call is disconnected, check the connections between the PHONE port and the analog phone, and between the EGW1520 FXO1 port and the PSTN. Specification One PSTN Power-off survival port. Limitation  The Power-off survival function is available only when a power off occurs.  Only the Analog Phone that connects to the PHONE port supports Power-off survival function. 7.3.4 Fax Service The EGW1520 supports fax service. Fax is a form of telegraphy for the transmission of fixed images with a view to their reproduction in a permanent form. In ITU-RV.662, faxing is defined as a form of telecommunication for the reproduction at a distance of graphic documents in the form of other graphic documents geometrically similar to the original. Description This topic describes the principle, implementation, specification, and limitation of the fax service. By transmission rate, faxes are divided into low-speed faxes (<= 14.4 kbit/s) and high-speed faxes (> 14.4 kbit/s). Low-speed faxes on an IP network are divided into transparently transmitted faxes (using G.711A or G.711u) and T.38 faxes. High-speed faxes, however, can only use G.711A or G.711u featuring low compression rate due to the requirement for high quality. The EGW1520 supports T.38 and transparent fax.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 132 Principle The fax service establishes a voice channel and switches the voice channel to a fax channel, including the IP address, port, codec, and channel types (audio, fax, and data). The voice channel is switched to a fax channel after the access device detects fax signals. The access device checks fax signals to determine whether the current fax is a high-speed or low-speed fax, and then delivers the fax signals to the NGN or IMS. The EGW1520 supports T.38 and transparent fax. Transparent fax: Fax signals are transmitted transparently as G.711 packets. G.711 faxes feature low delay and simple implementation, but they occupy a high bandwidth (fixed at 64 kbit/s) and are easily affected by network conditions. Therefore, G.711 faxes are recommended on a good network condition and not recommended when network jitter or packet loss frequently occur. G.711 faxes are applicable to high-speed and low-speed faxes. T.38 fax: T.30 fax signals are converted to T.38 packets for transmission on a packet switching network. T.38 faxes occupy a low bandwidth, provide high reliability with redundant frames and forward error checking (FEC), and are slightly affected by the network condition. However, the implementation is complicated. T.38 faxes are applicable only to low-speed fax services due to delay generated by the packet switching network. Implementation EGW1520 internal faxing The EGW1520 can access a fax machine through an FXS port. When two internal fax machines communicate with each other, the SIP server at the central center controls the fax call process. Figure 7-47 shows the network diagram.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 133 Figure 7-47 EGW1520 internal faxing The SIP server at the central node controls call signaling. The EGW1520 detects fax signals. The process for making a fax call is similar to that for making a call between two internal phones. After a call is made, the EGW1520 checks the fax signals and negotiates with the called and calling users about the fax media information. After the negotiation is successful, the voice channel is switched to the fax channel. Then the fax call is established. After the fax call is complete, the EGW1520 detects the fax ending signals and switches to the voice channel. EGW1520 external faxing When an internal fax machine communicates with an external fax machine, the fax service can be implemented through FXO ports or softswitch. The SIP server at the central node controls the external fax call process implemented through FXO ports. The softswitch (IMS/NGN) controls the external fax call process implemented through the softswitch. Figure 7-48 shows the network diagram when the softswitch is used.

The EGW1520 detects fax signals and encodes and decodes IP voice packets. After a fax call is established, fax media streams are transmitted over an IP network. The process for making a fax call is similar to that for making a call between an internal phone and an external phone. After the fax call is complete, the EGW1520 detects the fax ending signals and sends them to the NGN or IMS. The NGN or IMS negotiates with the calling and called users about the fax media information. After the negotiation is successful, the EGW1520 switches to the fax channel according to the NGN or IMS's signaling to establish a fax call. After the fax call is complete, the EGW1520 detects the fax ending signals and sends them to the NGN or IMS. Then the NGN or IMS switches to the voice channel.

eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 146 7.4 Voice(Common Mode) EGW1520 can function as a SIP trunk access device or a small-scale Internet protocol-private branch exchange (IP-PBX). It provides basic voice services and supplementary services. 7.4.1 Voice Access and IP PBX This topic describes the SIP trunk access and IP-PBX functions of EGW1520. Description The EGW1520 is deployed at the headquarters of an enterprise to connect to IADs, fax machines, IP phones, multimedia soft terminals, and WiFi terminals to implement voice user registration, call control, and protocol processing and provide rich voice services for enterprise users. In addition, the EGW1520 can work as a SIP trunk device to register users with the softswitch (NGN/IMS) and cooperate with the softswitch to process SIP signaling interaction, so that enterprise users can use services provide by the softswitch. Working Principle (SIP Trunk) A SIP trunk is a SIP link between a SIP trunk device and the SIP server. When an intra-office user calls an outer-office user, the SIP trunk device sends a message to the SIP server through the trunk. Then, the SIP server responds to the message and sets up the call between the two users. All the signaling and media streams between the SIP trunk and SIP server are transmitted over an IP network. SIP trunks usually function in the following modes:  Registration mode The IP address of the SIP server is configured on the SIP trunk device. The SIP trunk device sends a SIP REGISTER registers to the SIP server to create a dynamic SIP trunk link.  Static mode A SIP trunk device and a SIP server are equivalent NEs. The static IP address of the device is configured on the server and the static IP address of the server is configured on the device. A static SIP trunk is created between the device and the server. As a SIP trunk device, the EGW1520 supports the SIP trunk in registration mode. Intra-office calls are processed by the EGW1520. When there are outer-office calls, the EGW1520 cooperates with the softswitch (IMS/NGN) through the SIP trunk to process the SIP signaling interaction. Figure 7-57 shows the networking where the EGW1520 functions as a SIP trunk device.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 147 Figure 7-57 Connecting to the IMS/NGN through a SIP trunk EGW1520's registration and calling process is as follows: 1. The EGW1520 uses SIP Trunk to send a registration request to the softswitch (NGN/IMS). the softswitch (NGN/IMS) processes the registration request. If the authentication is successful, the softswitch (NGN/IMS) sends the success notification to the EGW1520. If the authentication fails, the softswitch (NGN/IMS) sends the failure notification to the EGW1520. When the registration is successful, EGW1520's SIP users can make or receive calls. 2. When an intra-office user makes a call, the EGW1520 analyzes the called number. If the called user is an intra-office user, the EGW1520 enables the called user's Analog phone to ring or sends a SIP message to the called user's SIP phone. The softswitch (NGN/IMS) does not process SIP messages for intra-office calls. If the called user is an outer-office user, the EGW1520 sends SIP requests to the softswitch (NGN/IMS). The EGW1520 cooperates with the softswitch to process the SIP signaling interaction. The called and calling users of a intra-office call are connected to the same the EGW1520. The called and calling users of an inter-office call are connected to different EGW1520s. 3. When receiving a call, the EGW1520 analyzes the called number. If the called user belongs to the EGW1520, the EGW1520 enables the called user's Analog phone to ring or sends a SIP message to the called user's SIP phone. If the called user is using a SIP phone, the EGW1520 also sends a SIP response to the peer device. If the called user does not belong to the EGW1520, the call fails and the EGW1520 sends a SIP response to the peer device. Working Principle (IP-PBX) When the EGW1520 connects to the PSTN as an IP-PBX, it implements call control, protocol processing, and voice functions on its own. Outgoing calls are made through FXO ports of the EGW1520. Figure 7-58 shows the network diagram when the EGW1520 functions as an IP-PBX.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 148 Figure 7-58 IP-PBX network diagram The EGW1520 allocates numbers to POTS and SIP users. Each number is unique. The EGW1520 can accept SIP users' registration. When receiving a registration request from a SIP user, the EGW1520 authenticates the SIP user. If the authentication is successful, the EGW1520 sends the success notification to the SIP user. If the authentication fails, the EGW1520 sends the failure notification to the SIP user. When the registration is successful, EGW1520's SIP users can make or receive calls. POTS users who are allocated numbers by the EGW1520 do not require registration. The registration is successful after pots users allocate numbers.  The EGW1520 analyzes the called number when an intra-office user initiates a call. If the call is an inter-office call call and the prefix of the called number matches the outgoing call prefix range configured on the EGW1520, the call is made through an FXO port. If the call is an intra-office call, the EGW1520 enables the user's POTS phone to ring or sends an SIP message to the user's SIP phone or soft terminal. The EGW1520 process calls made between intra-office users.  When the EGW1520 receives a call from an outer-office user, it analyzes the called number. If the called user connects to the EGW1520, the EGW1520 enables the called user's POTS phone to ring or sends a SIP message to the called user's SIP phone or soft terminal. If the called user is not connected to the EGW1520, the call fails and EGW1520 sends a response to the calling user through the SIP server. Specification  A maximum of 20 SIP users.  One FXS port, connecting to one POTS user.  A maximum of 8-channel users (SIP users and POTS users) can simultaneously initiate calls.

This topic describes the conflicts between services. Figure 7-69 shows the conflicts between services. Figure 7-69 Service conflicts
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 163  Glossary shows complete service names.  You cannot set conflicting services at the same time on the web management system. ?.2.Call Hold If a user configures the call holding service, the user can suspend a call and resume it as required. The call holding duration is not limited. Configuring the Service After enabling the call holding service, users can directly use it without configuration. Using the Service Assume that user A is an EGW1520's voice user. During a call with user B, user A can: 1. Press Hold or the hook flash button (for example, the R/Recall key) to suspend the call. User B hears the music-on-hold. 2. Press Hold or the hook flash button (for example, the R/Recall key) to resume the call. The operations may differ on IP phones of different models. For details, see the related IP phone user guide. ?.3.Call Transfer The call transfer service allows a user to quit a call in progress and transfer it to a third party. Configuring the Service After enabling the call transfer service, users can directly use it without configuration. Using the Service Assume that user A, an EGW1520 voice user who has enabled the call transfer service, is in a call with user B. User A wants to transfer the call to user C.  When using an analog phone, user A can: 1. Press the hook flash button and dial user C's number after hearing a dialing tone. User B hears a waiting tone. 2. Select an operation from the following: − Hang up the phone directly. − If user C is connected, user C's phone rings and user B hears the Ring Back Tone (RBT). After picking up the phone, user C talks with user B. − If user C cannot be connected, user B hears a busy tone. − Hang up the phone after user C is connected.
eSpace EGW1520 Enterprise Gateway Product Documentation 7 Feature Description and Implementation Issue 01 (2012-05-15) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 164 User C's phone rings and user B hears the RBT. After picking up the phone, user C talks with user B. − Hang up the phone after user C answers the call. User B talks with user C. − Talk with user B again. If user C is busy or does not respond, user A can press the hook flash button or wait 20 seconds to talk with user B again.  When using an IP phone, user A can use one of the following modes: − Unattend mode 1. User A presses the transfer key, dials the user C's number, and presses the send key. − User A's phone hangs up automatically, user B hears the RBT, and user C's phone rings. The process goes to step 2. − If user C is disconnected, the conversation between user A and user B resumes. 2. User C picks up the phone and talks with user B. − Attend mode In this mode, user A must use a SIP phone that supports multiple lines, for example, Polycom. 1. User A presses another idle line key (the indicator is off), for example, line 2. The conversation between user A and user B is held, and user B hears a waiting tone. 2. User A dials the user C's number and presses the send key. − User A hears the RBT and user C's phone rings. The process goes to step 3. − If user C is busy, user A hears a busy tone. After pressing the line key that connects to user B (line 1), user A resumes the conversation with user B. 3. User C picks up the phone and talks with user B. The conversation between user A and user C occupies another line (line 2 in the preceding example). 4. User A presses the transfer key, dials the user C's number, and presses the send key. User A's phone hangs up automatically, and user B talks with user C. − Semi-attend mode In this mode, user A must use a SIP phone that supports multiple lines, for example, Polycom. The procedure for user A to transfer a call in semi-attend mode is similar to that of attend mode. The only difference lies in that step 4 does not exist. In semi-attend mode, when user A hears the RBT (indicating that user C is connected), the call is transferred to user C. ?.4.Call Forwarding Unconditional After a user enables and configures the Call Forwarding Unconditional (CFU) service, all calls to the user will be forwarded to a preset number. Precautions The CFU service conflicts with some other services. For details, see Service Conflicts.
