Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 35 of 193 LDAP SERVER The UCM6510 has an embedded LDAP server for users to manage corporate phonebook in a centralized manner.  By default, the LDAP server has generated the first phonebook with PBX DN "ou=pbx,dc=pbx,dc=com" based on the UCM6510 user extensions already.  Users could add new phonebook with a different Phonebook DN for other external contacts. For example, "ou=people,dc=pbx,dc=com".  All the phonebooks in the UCM6510 LDAP server have the same Base DN "dc=pbx,dc=com". If users have the Grandstream phone provisioned by the UCM6510, the LDAP directory has been set up on the phone and can be used right away for users to access all phonebooks. Additionally, users could manually configure the LDAP client settings to manipulate the built-in LDAP server on the UCM6510. If the UCM6510 has multiple LDAP phonebooks created, in the LDAP client configuration, users could use "dc=pbx,dc=com" as Base DN to have access to all phonebooks on the UCM6510 LDAP server, or use a specific phonebook DN, for example "ou=people,dc=pbx,dc=com", to access to phonebook with Phonebook DN "ou=people,dc=pbx,dc=com " only. To access LDAP Server settings, go to web GUI->Settings->LDAP Server. LDAP SERVER CONFIGURATIONS The following figure shows the default LDAP server configurations on the UCM6510. Figure 7: LDAP Server Configurations

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 36 of 193 The UCM6510 LDAP server supports anonymous access (read-only) by default. Therefore the LDAP client doesn't have to configure username and password to access the phonebook directory. The "Root DN" and "Root Password" here are for LDAP management and configuration where users will need provide for authentication purpose before modifying the LDAP information. The default phonebook list in this LDAP server can be viewed and edited by clicking on for the first phonebook under LDAP Phonebook. Figure 8: Default LDAP Phonebook DN Figure 9: Default LDAP Phonebook Attributes LDAP PHONEBOOK Users could use the default phonebook, edit the default phonebook as well as add new phonebook on the LDAP server. The first phonebook with default phonebook dn "ou=pbx,dc=pbx,dc=com" displayed on the LDAP server page is for extensions in this PBX. Users cannot add or delete contacts directly. The contacts

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 37 of 193 information will need to be modified via web GUI->PBX->Basic/Call Routes->Extensions first. The default LDAP phonebook will then be updated automatically. A new sibling phonebook of the default PBX phonebook can be added by clicking on "Add" under "LDAP Phonebook" section. Figure 10: Add LDAP Phonebook Configure the "Phonebook Prefix" first. The "Phonebook DN" will be automatically filled in. For example, if configuring "Phonebook Prefix" as "people", the "Phonebook DN" will be filled with "ou=people,dc=pbx,dc=com". Once added, users can select to edit the phonebook attributes and contact list (see figure below), or select to delete the phonebook. Figure 11: Edit LDAP Phonebook

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 38 of 193 LDAP CLIENT CONFIGURATIONS The configuration on LDAP client is similar when you use other LDAP servers. Here we provide an example on how to configure the LDAP client on the SIP end points to use the default PBX phonebook. Assuming the server base dn is "dc=pbx,dc=com", configure the LDAP clients as follows (case insensitive): Base DN: dc=pbx,dc=com Login DN: Please leave this field empty Password: Please leave this field empty Anonymous: Please enable this option Filter: (|(CallerIDName=%)(AccountNumber=%)) Port: 389 To configure Grandstream IP phones as the LDAP client, please refer to the following example: Server Address: The IP address or domain name of the UCM6510 Base DN: dc=pbx,dc=com User Name: Please leave this field empty Password: Please leave this field empty LDAP Name Attribute: CallerIDName Email Department FirstName LastName LDAP Number Attribute: AccountNumber MobileNumber HomeNumber Fax LDAP Number Filter: (AccountNumber=%) LDAP Name Filter: (CallerIDName=%) LDAP Display Name: AccountNumber CallerIDName LDAP Version: If existed, please select LDAP Version 3 Port: 389 The following figure shows the configuration information on a Grandstream GXP2200 to successfully use the LDAP server as configured in Figure 7: LDAP Server Configurations.

If "Self-Defined Tome Zone" is selected, please specify the time zone parameters in "Self-Defined Time Zone" field as described in below option. Self-Defined Time Zone If "Self-Defined Time Zone" is selected in "Time Zone" option, users will need define their own time zone following the format below. The syntax is: std offset dst [offset], start [/time], end [/time] Default is set to: MTZ+6MDT+5,M4.1.0,M11.1.0 MTZ+6MDT+5 This indicates a time zone with 6 hours offset and 1 hour ahead for DST, which is U.S central time. If it is positive (+), the local time zone is west of the Prime Meridian (A.K.A: International or Greenwich Meridian); If it is negative (-), the local time zone is east. M4.1.0,M11.1.0 The 1st number indicates Month: 1, 2, 3..., 12 (for Jan, Feb, .., Dec). The 2nd number indicates the nth iteration of the weekday: (1st Sunday, 3rd Tuesday…). Normally 1, 2, 3, 4 are used. If 5 is used, it means the last iteration of the weekday. The 3rd number indicates weekday: 0,1,2,..,6 ( for Sun, Mon, Tues, ... ,Sat). Therefore, this example is the DST which starts from the First Sunday of April to the 1st Sunday of November. To manually set the time on the UCM6510, go to web GUI->Settings->Time Settings->Set Time Manually. The format is YYYY-MM-DD HH:MI:SS. Figure 15: Set Time Manually

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 45 of 193 PROVISIONING OVERVIEW Grandstream SIP Devices can be configured via web interface as well as via configuration file through TFTP/HTTP/HTTPS download. All Grandstream SIP devices support a proprietary binary format configuration file and XML format configuration file. The UCM6510 provides a Plug and Play mechanism to auto-provision the Grandstream SIP devices in a zero configuration manner by generating XML config file and having the phone to download it within LAN area. This allows users to finish the installation with ease and start using the SIP devices in a managed way. To provision a phone, three steps are involved, i.e., discovery, assignment and provisioning. The UCM6510 creates XML config file to the detected/assigned Grandstream device and accomplishes the following configurations on the device after the provisioning:  A UCM6510 extension will be assigned and registered on the phone.  SIP-related network settings such as "NAT traversal" and "Use Random Port" are configured on the phone.  Call feature settings such as "Public Mode", "Voicemail User ID", "Dial Plan" and "Auto Answer".  LDAP client configurations will be set up automatically on the phone to use the default LDAP directory generated in the UCM6510 LDAP server. This section explains how zero config works on the UCM6510. The settings for this feature can be accessed via web GUI->PBX->Basic/Call Routes->Zero Config. AUTO PROVISIONING By default, the Zero Config feature is enabled on the UCM6510 for auto provisioning. Three methods of auto provisioning are used.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 47 of 193 Figure 17: Auto Provision Settings Table 16: Auto Provision Settings Enable Zero Config Enable or disable the zero config feature on the PBX. The default setting is disabled. Automatically Assign Extension If enabled, when the device is discovered, the PBX will automatically assign an extension within the range defined in "Zero Config Extension Segment" to the device. The default setting is disabled. Zero Config Extension Segment Click on the link "Zero Config Extension Segment" to specify the extension range to be assigned if "Automatically Assign Extension" is enabled. The default range is 5000-6299. Enable Pick Extension If enabled, the extension list will be sent out to the device after receiving the device's request. This feature is for the GXP phones that support selecting extension to be provisioned via phone's LCD. The default setting is disabled. Pick Extension Segment Click on the link "Pick Extension Segment" to specify the extension list to be sent to the device. The default range is 4000 to 4999. Pick Extension Period (hour): Specify the number of minutes to allow the phones being provisioned to pick extensions.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 48 of 193 Please make sure an extension is manually assigned to the phone or "Automatically Assign Extension" is enabled during provisioning. After the configuration on the UCM6510 web GUI, click on "Save" and "Apply Changes". Once the phone boots up and picks up the config file from the UCM6510, it will take the configuration right away. MANUAL PROVISIONING DISCOVERY Users could manually discover the device by specifying the IP address or scanning the entire LAN network. Three methods are supported to scan the devices.  PING  ARP  SIP Message (NOTIFY) Click on "Auto Discover", fill in the "Scan Method" and "Scan IP". The IP address segment will be automatically filled in based on the network mask detected on the UCM6510. If users need scan the entire network segment, enter 255 (for example, 192.168.40.255) instead of a specific IP address. Then click on "Save" to start discovering the devices within the same network. To successfully discover the devices, "Zero Config" needs to be enabled on the UCM6510 web GUI->PBX->Basic/Call Routes->Zero Config->Auto Provisioning Settings. Figure 18: Auto Discover The following figure shows a list of discovered phones. The MAC address, IP Address, Extension (if assigned), Version, Vendor, Model, Connection Status, Create Config, Options (Edit/Delete/Update) are displayed in the list.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 49 of 193 Figure 19: Discovered Devices ASSIGNMENT In the discovered list, click on to open the edit dialog to assign an extension or multiple extensions to this device. Hot-Desking can also be enabled from this edit page. Figure 20: Assign Extension To Device After saving the edit dialog, the XML config file will be generated in the UCM6510. Reboot the phone or trigger the phone to download the config file by clicking on icon for the entry in the zero config device list.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 50 of 193 CREATE NEW DEVICE Users could also directly create a new device and assign the extension before the device is discovered by the UCM6510. Once the device is plugged in, it can then be discovered and provisioned by the UCM6510. Click on "Create New Device" and the following dialog will show. Enabled Hot-Desking (optional), fill in the MAC address (required), IP address (optional), Version (optional), Model (optional) and the extension (required) to assign to the device.

Note: If enabled, Fax Pass-through cannot be used. DIRECT OUTWARD DIALING (DOD) VIA VOIP TRUNKS The UCM6510 provides Direct Outward Dialing (DOD) which is a service of a local phone company (or local exchange carrier) that allows subscribers within a company's PBX system to connect to outside lines directly. Example of how DOD is used: Company ABC has a SIP trunk. This SIP trunk has 4 DIDs associated to it. The main number of the office is routed to an auto attendant. The other three numbers are direct lines to specific users of the company. At the moment when a user makes an outbound call their caller ID shows up as the main office number. This poses a problem as the CEO would like their calls to come from their direct line. This can be accomplished by configuring DOD for the CEO’s extension. Steps on how to configure DOD on the UCM: 1. To setup DOD go to UCM6510 web GUI->PBX->Basic/Call Routes->VoIP Trunks page. 2. Click to access the DOD options for the selected SIP Trunk. 3. Click "Create a new DOD" to begin your DOD setup 4. For "DOD Number" enter one of the numbers(DIDs) from your SIP trunk provider. In the example above Company ABC received 4 DIDs from their provider. ABC will enter in the number for the CEO's direct line. 5. Select an extension from the "Available Extensions" list. Users have the option of selecting more than one extension. In this case, Company ABC would select the CEO's extension. After making the selection, click on the button to move the extension(s) to the "Selected Extensions" list.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 91 of 193 CALL ROUTES OUTBOUND ROUTES In the UCM6510, an outgoing calling rule pairs an extension pattern with a trunk used to dial the pattern. This allows different patterns to be dialed through different trunks (e.g., "Local" 7-digit dials through a FXO while "Long distance" 10-digit dials through a low-cost SIP trunk). Users can also set up a failover trunk to be used when the primary trunk fails. Go to web GUI->PBX->Basic/Call Routes->Outbound Routes to add and edit outbound rules.  Click on "Create New Outbound Rule" to add a new outbound route.  Click on to edit the outbound route.  Click on to delete the outbound route.  Click on to move the outbound route up/down to arrange the priority of the outbound rule. The outbound rule listed on the top has higher priority. When the dialing pattern matches two or more outbound rules (for example, the same pattern is configured for 2 different trunks; or dialing out 1000 matches pattern 1xxx for trunk 1 and pattern 100x for trunk 2), the one listed on the top will be used. Table 29: Outbound Route Configuration Parameters Calling Rule Name Configure the name of the calling rule (e.g., local, long_distance, and etc). Letters, digits, _ and - are allowed. Pattern  All patterns are prefixed with the "_".  Special characters: X: Any Digit from 0-9. Z: Any Digit from 1-9. N: Any Digit from 2-9. ".": Wildcard. Match one or more characters. "!": Wildcard. Match zero or more characters immediately. Example: [12345-9] - Any digit from 1 to 9. Password Configure the password for users to use this rule when making outbound calls. Privilege Level Select privilege level for the outbound rule.  Internal: The lowest level required. All users can use this rule.  Local: Users with Local, National, or International level are allowed

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 92 of 193 to use this rule.  National: Users with National or International level are allowed to use this rule.  International: The highest level required. Only users with international level can use this rule. The default setting is "International". Please be aware of the potential security risks when using "Internal" level, which means all users can use this outbound rule to dial out from the trunk. Enable Filter on Source Caller ID When enabled, users could specify extensions allowed to use this outbound route. "Privilege Level" is automatically disabled if using "Enable Filter on Source Caller ID". The following two methods can be used at the same time to define the extensions as the source caller ID. 1. Select available extensions from the left to the right. This allows users to specify arbitrary single extensions. 2. Custom Dynamic Route: define the pattern for the source caller ID. This allows users to define extension range instead of selecting them one by one.  All patterns are prefixed with the "_".  Special characters: X: Any Digit from 0-9. Z: Any Digit from 1-9. N: Any Digit from 2-9. ".": Wildcard. Match one or more characters. "!": Wildcard. Match zero or more characters immediately. Example: [12345-9] - Any digit from 1 to 9. Send This Call Through Trunk Use Trunk Select the trunk for this outbound rule. Strip Allows the user to specify the number of digits that will be stripped from the beginning of the dialed string before the call is placed via the selected trunk. Example: The users will dial 9 as the first digit of a long distance calls. However, 9 should not be sent out via analog lines and the PSTN line. In this case, 1 digit should be stripped before the call is placed.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 93 of 193 Prepend Specify the digits to be prepended before the call is placed via the trunk. Those digits will be prepended after the dialing number is stripped. Use Failover Trunk Failover Trunk Failover trunks can be used to make sure that a call goes through an alternate route, when the primary trunk is busy or down. If "Use Failover Trunk" is enabled and "Failover trunk" is defined, the calls that cannot be placed via the regular trunk may have a secondary trunk to go through. Example: The user's primary trunk is a VoIP trunk and the user would like to use the PSTN when the VoIP trunk is not available. The PSTN trunk can be configured as the failover trunk of the VoIP trunk. Strip Allows the user to specify the number of digits that will be stripped from the beginning of the dialed string before the call is placed via the selected trunk. Example: The users will dial 9 as the first digit of a long distance calls. However, 9 should not be sent out via analog lines and the PSTN line. In this case, 1 digit should be stripped before the call is placed. Prepend Specify the digits to be prepended before the call is placed via the trunk. Those digits will be prepended after the dialing number is stripped. INBOUND ROUTES Inbound routes can be configured via web GUI->PBX->Basic/Call Routes->Inbound Routes.  Click on "Create New Inbound Rule" button to add a new inbound route.  Click on "Blacklist" button to configure blacklist for all inbound routes.  Click on to edit the inbound route.  Click on to delete the inbound route.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 94 of 193 INBOUND RULE CONFIGURATIONS Table 30: Inbound Rule Configuration Parameters Trunks Select the trunk to configure the inbound rule. DID Pattern  All patterns are prefixed with the "_".  Special characters: X: Any Digit from 0-9. Z: Any Digit from 1-9. N: Any Digit from 2-9. ".": Wildcard. Match one or more characters. "!": Wildcard. Match zero or more characters immediately. Example: [12345-9] - Any digit from 1 to 9.  The pattern can be composed of two parts, divided by a ‘/’ character. The first part is used to specify the dialed number the second part is used to specify the caller ID and it is optional, if set it means only the extension with the specific caller ID is allowed to call in or call out. For example, patter '_2XXX/1234' means the only extension with the caller ID '1234' is allowed to use this rule. Privilege Level Select privilege level for the inbound rule when a VoIP trunk is selected in "Trunks" field.  Internal: The lowest level required. All users can use this rule.  Local: Users with Local, National or International level are allowed to use this rule.  National: Users with National or International level are allowed to use this rule.  International: The highest level required. Only users with international level can use this rule. This setting is used to compared with the outbound trunk's permission level when the inbound call dials out via a trunk on the UCM6510. Therefore, it's usually used only when the "Default Destination" is set to "By DID". Default Destination Select the default destination for the inbound call.  Extension  Voicemail  Conference Room  Call Queue  Ring Group  Paging/Intercom  Voicemail Group

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 169 of 193 CDR A Call Detail Record (CDR) is a data record produced by telephone exchange activities or other telecommunications equipment documenting the details of a phone call that passed through the PBX. The CDR is composed of the following data fields on the UCM6510.  Start Time. Format: 2013-03-27 16:47:03.  Call From. Format: "John Doe"<6012>.  Call To. Format: 6005.  Call Time. Format: 0:00:10.  Talk Time. Format: 0:00:10  Status. Format: NO ANSWER, BUSY, ANSWERED, or FAILED.  Options. Voice record playing/downloading/deleting. Users could filter the call report by specifying the date range and criteria, depending on how the users would like to include the logs to the report. Then click on "View Report" button to display the generated report. Figure 83: CDR Filter Table 64: CDR Filter Criteria Inbound calls Inbound calls are calls originated from a non-internal source (like a VoIP trunk) and sent to an internal extension. Outbound calls Outbound calls are calls sent to a non-internal source (like a VoIP trunk) from an internal extension. Internal calls Internal calls are calls from one internal extension to another extension, which are not sent over a trunk. External calls External calls are calls sent from one trunk to another trunk, which are not sent to

Caller Name Enter the caller name to be filtered in the CDR report. From Date Specify "From" date and time to be filtered for the CDR report. Click on the field and the calendar will show for users to select the exact date and time. To Date Specify "To" date and time to be filtered for the CDR report. Click on the field and the calendar will show for users to select the exact date and time. The call report will display as the following figure shows. Figure 84: Call Report Users could perform the following operations on the call report.  Sort Click on the header of the column to sort by this category. For example, clicking on "Start Time" will sort the report according to start time. Clicking on "Start Time" again will reverse the order.  Download Records On the bottom of the page, click on "Download Records" button to export the report in .csv format.  Delete All On the bottom of the page, click on "Delete All" button to remove all the call report information.  Play/Download/Delete Recording File (per entry) If the entry has audio recording file for the call, the three icons on the most right column will be activated for users to select. In the following picture, the second entry has audio recording file for the call.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 171 of 193 Click on to play the recording file; click on to download the recording file in .wav format; click on to delete the recording file (the call record entry will not be deleted). Figure 85: Call Report Entry With Audio Recording File DOWNLOADED CDR FILE The downloaded CDR (.csv file) has different format from the web UI CDR. Here are some descriptions.  Call From, Call To "Call From": the caller ID. "Call To": the callee ID. If "Call From" shows empty, "Call To" shows "s" (see highlight part in the picture below) and the "Source Channel" contains "DAHDI", this means the call is from FXO/PSTN line. For FXO/PSTN line, we only know there is an incoming request when there is incoming call but we don't know the number being called. So we are using "s" to match it where "s" means "start". Figure 86: Downloaded CDR File Sample - Call To Shows "s"  Context There are different context values that might show up in the downloaded CDR file. The actual value can vary case by case. Here are some sample values and their descriptions. from-internal: internal extension makes outbound calls. ext-did-XXXXX: inbound calls. It starts with "ext-did", and "XXXXX" content varies case by case, which also relate to the order when the trunk is created. ext-local: internal calls between local extensions.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 172 of 193  Source Channel, Dest Channel Sample 1: Figure 87: Downloaded CDR File Sample - Source Channel and Dest Channel 1 DAHDI means it is an analog call, FXO or FXS. For UCM6510, DAHDI/(1-2) are FXO ports, and DAHDI(3-4) are FXS ports. For UCM6510, DAHDI/(1-4) are FXO ports, and DAHDI(5-6) are FXS ports. For UCM6510, DAHDI/(1-8) are FXO ports, and DAHDI(9-10) are FXS ports. For UCM6510, DAHDI/(1-16) are FXO ports, and DAHDI/(17-18) are FXS ports. Sample 2: Figure 88: Downloaded CDR File Sample - Source Channel and Dest Channel 2 "SIP" means it's a SIP call. There are three possible format: (a) SIP/NUM-XXXXXX, where NUM is the local SIP extension number. The last XXXXX is a random string and can be ignored. (c) SIP/trunk_X/NUM, where trunk_X is the internal trunk name, and NUM is the number to dial out through the trunk. (c) SIP/trunk_X-XXXXXX, where trunk_X is the internal trunk name and it is an inbound call from this trunk. The last XXXXX is a random string and can be ignored. Sample 3: Figure 89: Downloaded CDR File Sample - Source Channel and Dest Channel 3 This is a very special channel name. If it shows up, most likely it means a conference call. There are some other possible values, but these values are almost the application name which are used by the dialplan. IAX2/NUM-XXXXXXX: it means this is an IAX call. Local/@from-internal-XXXXX: it is used internally to do some special feature procedure. We can simply ignore it. Hangup: the call is hung up from the dialplan. This indicates there are some errors or it has run into

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 173 of 193 abnormal cases. Playback: play some prompts to you, such as 183 response or run into an IVR. ReadExten: collect numbers from user. It may occur when you input PIN codes or run into DISA STATISTICS CDR Statistics is an additional feature on the UCM6510 which provides users a visual overview of the call report across the time frame. Users can filter with different criteria to generate the statistics chart. Figure 90: CDR Statistics Table 65: CDR Statistics Filter Criteria Trunk Type Select one of the following trunk type.  All  SIP Calls  PSTN Calls Call Type Select one or more in the following checkboxes.  Inbound calls  Outbound calls  Internal calls  External calls  All calls Time Range  By month (of the selected year).  By week (of the selected year).  By day (of the specified month for the year).  By hour (of the specified date).  By range. For example, 2013-01 To 2013-03.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 174 of 193 RECORDING FILES The recording files recorded by "Auto Record" per extension/per trunk, or via feature code "Audio Mix Record" are listed here. Users could click on to play the recording file; click on to download the recording file in .wav format; or click on to delete the recording file. To sort the recording file, click on the title "Caller", "Callee" or "Call Time" for the corresponding column. Click on the title again can switch the sorting mode between ascending order or descending order. CDR API CONFIGURATION FILES The UCM6510 supports third party billing interface API for external billing software to access CDR on the PBX. The API uses HTTPS to request the CDR data matching given parameters as configured on the third party application. Before accessing the API, the administrators need enable API and configure the access/authentication information on the UCM6510 first. Table 66: CDR API Configuration Files Enable Enable/Disable CDR API. The default setting is disabled. TLS Bind Address Configure the IP address for TLS server to bind to. "0.0.0.0" means binding to all interfaces. The port number is optional and the default port number is 8443. The IP address must match the common name (host name) in the certificate so that the TLS socket won't bind to multiple IP addresses. The default setting is 0.0.0.0:8443. TLS Private Key Upload TLS private key. The size of the key file must be under 2MB. This file will be renamed as 'private.pem' automatically. TLS Cert Upload TLS cert. The size of the certificate must be under 2MB. This is the certificate file (*.pem format only) for TLS connection. This file will be renamed as "certificate.pem" automatically. It contains private key for the client and signed certificate for the server. TLS Authentication Name Configure the user name for TLS authentication. If not configured, authentication will be skipped. TLS Authentication Password Configure the password for TLS authentication. This is optional. Permitted Specify a list of IP addresses permitted by CDR API. This creates an AIP-specific access control list. Multiple entries are allowed. For example, "192.168.40.3/255.255.255.255" denies access from all IP addresses except 192.168.40.3.

Firmware Version 1.0.0.5 UCM6510 IP PBX User Manual Page 175 of 193 The format of the HTTPS request for the CDR API is as below. https://[UCM IP]:[Port]/cdrapi?[option1]=[value]&[option2]=[value]&... By default, the port number for the API is 8443. The options included in the request URI control the record matching and output format. For CDR matching parameters, all non-empty parameters must have a match to return a record. Parameters can appear in the URI in any order. Multiple values given for caller or callee will be concatenated. The following table shows the parameter list used in the CDR API. Table 67: CDR API URI Parameters Field Value Details format csv, xml, json Define the format for output of matching CDR rows. Default is csv (comma separated values). numRecords Number: 0-1000 Number of records to return. Default is 1000, which is also the maximum allowed value. offset Number Number of matching records to skip. This will be combined with numRecords to receive all matches over multiple responses. Default is 0. caller Comma separated extensions, ranges of extensions, or regular expressions. Example: caller=5300,5302-5304,_4@ -OR- caller=5300&caller=5302-5304&caller=_4@ (Matches extensions 5300, 5302, 5303, 5304, and any extension containing 4 as the second digit/character). Filters based on src (caller) or dst (callee) value, matching any extension contained in the parameter input string. Patterns containing one or more wildcards ('@' or '_') will match as a regular expression, and treat '-' as a literal hyphen rather than a range signifier. The '@' wildcard matches any number of characters (including zero), while '_' matches any single character. Otherwise, patterns containing a single hyphen will be matching a range of numerical extensions, with non-numerical characters ignored, while patterns containing multiple hyphens will be ignored. (The pattern "0-0" will match all non-numerical and empty strings). callee

Calls which start within this period (inclusive of boundaries) will match, regardless of the call answer or end time. An empty value for either field will be interpreted as range with no minimum or maximum respectively. Strings without a date have a default value of 2000-01-01. Strings without a time of day have a default value of of 00:00 UTC, while strings with a time of day specified may also optionally specify a time zone offset - replace '+' in time zone offset with '%2B' (see http://www.w3.org/TR/NOTE-datetime). endTime minDur Number (duration in seconds) Filters based on the billsec value, the duration between call answer and call end. maxDur Example Queries: The following illustrates the format of queries to accomplish certain requests. In most cases, multiple different queries will accomplish the same goal, and these examples are not intended to be exhaustive, but rather to bring attention to particular features of the CDR API connector.
