.. _how_to_configure_sip_trunks: .. rst-class:: chapter-with-expand Configure SIP Trunks ---------------------- This procedure adds new SIP trunks and edits existing SIP trunks. **Perform these steps**: 1. Log in as provider, reseller, or customer administrator. 2. Set the hierarchy path to the node where the Cisco Unified Communications Manager is configured. 3. How are you logged in? * Provider or reseller administrator? Go to **Apps Management > CUCM > SIP Trunks**. * Customer administrator? Go to **Apps Management > Advanced > SIP Trunks**. 4. Do you want to ... * Add a new SIP trunk? Click **Add**, then go to Step 5. * Edit an existing SIP trunk? Click on the relevant SIP trunk in the list of SIP trunks; then, go to step 6. 5. From the **CUCM** drop-down menu, select the hostname, domain name, or IP address of the Unified CM where you want to add the SIP trunk. .. note:: The **CUCM** drop-down displays only when you're adding a new SIP trunk (not when editing). This drop-down menu displays the Unified CM located at the node, and all the Unified CM nodes in the hierarchies above the node where you're adding the SIP trunk. To provision a Unified CM server, see the Installation Tasks section of Installing Cisco Unified Communications Manager. 6. In the **Device Name** field, enter a unique name for the new SIP trunk (or modify the existing device name, as applicable). 7. On the **Device Information** tab, complete at minimum, the mandatory :ref:`device_information_fields`. 8. On the **Call Routing General** tab, complete at minimum, the mandatory :ref:`call_routing_general_fields`. 9. On the **Call Routing Inbound** tab, complete the required :ref:`call_routing_inbound_fields`. 10. On the **Call Routing Outbound** tab, complete the required :ref:`call_routing_outbound_fields`. 11. On the **SP Info** tab, complete the required :ref:`sp_info_fields`. 12. On the **GeoLocation** tab, complete at minimum, the mandatory :ref:`geolocation_fields`. 13. Click **Save** to save a new or updated SIP trunk. The SIP trunk appears in the SIP trunk list. The SIP trunk is automatically reset on the Unified CM as soon as it's added. To reset the SIP trunk at any other time, see "Reset SIP Trunk". To view the SIP trunk and its properties, log in to the Unified CM where you added the SIP trunk, select Device Trunk, and perform the "Find" operation. Clicking on the SIP trunk name in the list displays its characteristics. .. _device_information_fields: Device Information Tab ......................... .. tabularcolumns:: |p{3.5cm}|p{12cm}| +------------------------+-----------------------------------------------+ | Option | Description | +========================+===============================================+ | | Enter a unique identifier for the trunk using | | Device Name \* | up to 50 alphanumeric characters: A-Z, a-z, | | | numbers, hyphens (-) and underscores (_) | | | only. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | Choose one of: | | | | | | * **None** - Choose this option if the trunk | | | is not used for call control discovery, | | | Extension Mobility Cross Cluster, or | | | Cisco Intercompany Media Engine | | | * **Call Control Discovery** - Choose this | | | option to enable the trunk to support | | | call control discovery. | | | * **Extension Mobility Cross Cluster** - | | | Choose this option to enable the trunk to | | | support the Extension Mobility Cross | | | Cluster (EMCC) feature. Choosing this | | | option causes the following settings to | | | remain blank or clear and become | | Trunk Service Type | unavailable for configuration, thus | | | retaining their default values: Media | | | Termination Point Required, Unattended | | | Port, Destination Address, Destination | | | Address IPv6, and Destination Address is | | | an SRV. | | | * **Cisco Intercompany Media Engine** - Ensure| | | that the Cisco IME server is installed and | | | available before you configure this field. | | | * **IP Multimedia Subsystem Service Control | | | (ISC)** - Choose this option to enable the | | | trunk to support IP multimedia subsystem | | | service control. | | | | | | Default value: None (Default) | +------------------------+-----------------------------------------------+ | | Enter a descriptive name for the trunk using | | | up to 114 characters in any language, but not | | | including double-quotes (\"), percentage sign | | Description (Optional) | (%), ampersand (&), backslash (\\), or angle | | | brackets (<>). | | | | | | Default value: empty | +------------------------+-----------------------------------------------+ | | Choose the appropriate device pool for the | | | trunk. For trunks, device pools specify a | | | list of Cisco Unified Communications Managers | | | (Unified CMs) that the trunk uses to | | | distribute the call load dynamically. | | | | | | Note: | | | | | | Calls that are initiated from a phone that is | | | registered to a Unified CM that does not | | Device Pool \* | belong to the device pool of the trunk use | | | different Unified CMs of this device pool for | | | different outgoing calls. Selection of | | | Unified CM nodes occurs in a random order. A | | | call that is initiated from a phone that is | | | registered to a Unified CM that does belong | | | to the device pool of the trunk uses the same | | | Unified CM node for outgoing calls if the | | | Unified CM is up and running. | | | | | | Default value: Default | +------------------------+-----------------------------------------------+ | | Choose the common device configuration to | | Common Device | which you want this trunk assigned. The | | Configuration | common device configuration includes the | | | attributes (services or features) that are | | | associated with a particular user. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | This parameter determines whether an incoming | | | call through this trunk is considered off the | | | network (OffNet) or on the network (OnNet). | | | When the Call Classification field is | | | configured as Use System Default, the setting | | Call Classification | of the Unified CM clusterwide service | | | parameter, Call Classification, determines | | | whether the trunk is OnNet or OffNet.

An application chooses | | Media Resource Group | the required media resource, such as a Music | | List | On Hold server, from among the available | | | media resources according to the priority | | | order that a Media Resource Group List | | | defines. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | Use locations to implement call admission | | | control (CAC) in a centralized | | | call-processing system. CAC enables you to | | | regulate audio quality and video availability | | | by limiting the amount of bandwidth that is | | | available for audio and video calls over | | | links between locations. The location | | | specifies the total bandwidth that is | | | available for calls to and from this | | | location. | | | | | | Choose the appropriate location for this | | Location \* | trunk: | | | | | | * Hub_None - Specifies that the locations | | | feature does not keep track of the | | | bandwidth that this trunk consumes. | | | * Phantom - Specifies a location that | | | enables successful CAC across | | | intercluster trunks that use H.323 | | | protocol or SIP. | | | * Shadow - Specifies a location for | | | intercluster enhanced location CAC. Valid | | | for SIP intercluster trunks (ICT) only. | | | | | | Default value: Hub_None | +------------------------+-----------------------------------------------+ | | Choose the automated alternate routing (AAR) | | | group for this device. The AAR group provides | | | the prefix digits that are used to route | | AAR Group | calls that are otherwise blocked due to | | | insufficient bandwidth. An AAR group setting | | | of None specifies that no rerouting of | | | blocked calls is attempted. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | Choose the QSIG option if you want to use SIP | | | trunks or SIP gateways to transport (tunnel) | | | QSI messages from Unified CM to other PINXs. | | | QSIG tunneling supports the following | | Tunneled Protocol | features: Call Back, Call Completion, Call | | | Diversion, Call Transfer, Identification | | | Services, Path Replacement, and Message | | | Waiting Indication (MWI). | | | | | | Note: Remote-Party-ID (RPID) headers coming | | | in from the SIP gateway can interfere with | | | QSIG content and cause unexpected behavior | | | with Call Back capabilities. To prevent | | | interference with the QSIG content, turn off | | | the RPID headers on the SIP gateway. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | To display the options in the **QSIG Variant**| | | drop-down list, choose QSIG from the | | | **Tunneled Protocol** drop-down menu. This | | | parameter specifies the protocol profile that | | | is sent in outbound QSIG facility information | | | elements. | | | | | | From the drop-down menu, select one of: | | | | | | * No Changes - Default.

After you | | | complete packet capturing, configure this | | | setting. | | | * Batch Processing Mode - Unified CM writes | | | the decrypted or nonencrypted messages to | | | a file, and the system encrypts each | | | file. On a daily basis, the system | | | creates a new file with a new encryption | | | key. Unified CM, which stores the file | | Packet Capture Mode | for seven days, also stores the keys that | | | encrypt the file in a secure location. | | | Unified CM stores the file in the PktCap | | | virtual directory. A single file contains | | | the time stamp, source IP address, source | | | IP port, destination IP address, packet | | | protocol, message length, and the | | | message. The TAC debugging tool uses | | | HTTPS, administrator username and | | | password, and the specified day to | | | request a single encrypted file that | | | contains the captured packets. Likewise, | | | the tool requests the key information to | | | decrypt the encrypted file. Before you | | | contact TAC, you must capture the SRTP | | | packets by using a sniffer trace between | | | the affected devices. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | This setting exists for troubleshooting | | | encryption only; packet capturing may cause | | | high CPU usage or call-processing | | | interruptions. This field specifies the | | Packet Capture | maximum number of minutes that is allotted | | Duration | for one session of packet capturing. | | | | | | To initiate packet capturing, enter a value | | | other than 0 in the field. After packet | | | capturing completes, the value, 0, displays. | | | | | | Default value: 0 (zero), Range is from 0 to | | | 300 minutes | +------------------------+-----------------------------------------------+ .. tabularcolumns:: |p{3.5cm}|p{12cm}| +------------------------+-----------------------------------------------+ | Option | Description | +========================+===============================================+ | | You can configure Unified CM SIP trunks to | | | always use an Media Termination Point (MTP). | | | Select this box to provide media channel | | | information in the outgoing INVITE request. | | | When this check box is selected, all media | | | channels must terminate and reoriginate on | | | the MTP device. If you clear the check box, | | | the Unified CM can decide whether calls are | | | to go through the MTP device or be connected | | | directly between the endpoints. | | | | | | Note: | | | | | Media Termination | If the check box remains clear, Unified CM | | Point Required | attempts to dynamically allocate an MTP if | | | the DTMF methods for the call legs are not | | | compatible. For example, existing phones that | | | run SCCP support only out-of-band DTMF, and | | | existing phones that run SIP support RFC2833. | | | Because the DTMF methods are not identical, | | | the Unified CM dynamically allocates an MTP. | | | If, however, a new phone that runs SCCP, | | | which supports RFC2833 and out-of band, calls | | | an existing phone that runs SIP, Unified CM | | | does not allocate an MTP because both phones | | | support RFC2833. So, by having the same type | | | of DTMF method supported on each phone, there | | | is no need for MTP. | | | | | | Default value: False (Cleared) | +------------------------+-----------------------------------------------+ | | This check box pertains to outgoing SIP trunk | | | calls and does not impact incoming calls. By | | | default, the system selects this check box to | | | specify that this device should immediately | | | retry a video call as an audio call (if it | | | cannot connect as a video call) prior to | | Retry Video Call as | sending the call to call control for | | Audio | rerouting. If you clear this check box, a | | | video call that fails to connect as video | | | does not try to establish as an audio call. | | | The call then fails to call control, and call | | | control routes the call using Automatic | | | Alternate Routing (AAR) and route list or | | | hunt list. | | | | | | Default value: True (Selected) | +------------------------+-----------------------------------------------+ | | This check box is relevant when you select | | | QSIG from the **Tunneled Protocol** drop-down | | Path Replacement | menu. This setting works with QSIG tunneling | | Support | to ensure that non-SIP information gets sent | | | on the leg of the call that uses path | | | replacement. | | | | | | Default value: False (Clear) | +------------------------+-----------------------------------------------+ | | This device uses the user locale setting of | | | the device pool to determine whether to send | | | unicode and whether to translate received | | | Unicode information. For the sending device, | | | if you select this check box and the user | | | locale setting in the device pool matches the | | | terminating phone user locale, the device | | | sends unicode. If the user locale settings do | | | not match, the device sends ASCII. The | | | receiving device translates incoming unicode | | Transmit UTF-8 for | characters based on the user locale setting | | Calling Party Name | of the sending device pool. If the user | | | locale setting matches the terminating phone | | | user locale, the phone displays the | | | characters. | | | | | | Note: | | | | | | The phone may display malformed characters if | | | the two ends of the trunk are configured with | | | user locales that do not belong to the same | | | language group. | | | | | | Default value: False (Cleared) | +------------------------+-----------------------------------------------+ .. tabularcolumns:: |p{3.5cm}|p{12cm}| +------------------------+-----------------------------------------------+ | Option | Description | +========================+===============================================+ | | This device uses the user locale setting of | | | the device pool to determine whether to send | | | unicode and whether to translate received | | | Unicode information. For the sending device, | | | if you select this check box and the user | | | locale setting in the device pool matches the | | | terminating phone user locale, the device | | Transmit UTF-8 Names | sends unicode and encodes in UTF-8 format. If | | for QSIG APDU | the user locale settings do not match, the | | | device sends ASCII and encodes in UTF-8 | | | format. If the configuration parameter is not | | | set and the user locale setting in the device | | | pool matches the terminating phone user | | | locale, the device sends unicode (if the name | | | uses 8 bit format) and encodes in ISO8859-1 | | | format. | | | | | | Default value: False (Cleared) | +------------------------+-----------------------------------------------+ | | Select this check box if calls can be | | Unattended Port | redirected and transferred to an unattended | | | port, such as a voice mail port. | | | | | | Default value: False (Cleared) | +------------------------+-----------------------------------------------+ | | Select this check box if you want Unified CM | | | to allow secure and nonsecure media calls | | | over the trunk. Selecting this check box | | | enables Secure Real-Time Protocol (SRTP) SIP | | | Trunk connections and also allows the SIP | | | trunk to fall back to Real-Time Protocol | | | (RTP) if the endpoints do not support SRTP. | | | If you do not select this check box, Unified | | | CM prevents SRTP negotiation with the trunk | | | and uses RTP negotiation instead. | | | | | SRTP Allowed | Caution: | | | | | | If you select this check box, we strongly | | | recommend that you use an encrypted TLS | | | profile, so that keys and other security | | | related information do not get exposed during | | | call negotiations. If you use a non-secure | | | profile, SRTP still works but the keys get | | | exposed in signaling and traces. In that | | | case, you must ensure the security of the | | | network between Unified CM and the | | | destination side of the trunk. | | | | | | Default value: False (Cleared) | +------------------------+-----------------------------------------------+ | | This field provides an extension to the | | | existing security configuration on the SIP | | | trunk, which enables a SIP trunk call leg to | | | be considered secure if SRTP is negotiated, | | | independent of the signaling transport. | | Consider Traffic on | | | This Trunk Secure | From the drop-down menu, select one of: | | | | | | * When using both sRTP and TLS | | | * When using sRTP Only - Displays when you | | | select the **SRTP Allowed** check box. | | | | | | Default value: When using both sRTP and TLS | +------------------------+-----------------------------------------------+ .. tabularcolumns:: |p{3.5cm}|p{12cm}| +------------------------+-----------------------------------------------+ | Option | Description | +========================+===============================================+ | | From the drop-down menu, enable or disable | | | route class signaling for the port. Route | | | class signaling communicates special routing | | | or termination requirements to receiving | | | devices. It must be enabled for the port to | | | support the Hotline feature. | | | | | | From the drop-down menu, select one of: | | | | | | * Default - The device uses the setting | | Route Class Signaling | from the Route Class Signaling service | | Enabled | parameter | | | * Off - Enables route class signaling. This | | | setting overrides the Route Class | | | Signaling service parameter | | | * On - Disables route class signaling. This | | | setting overrides the Route Class | | | Signaling service parameter. | | | | | | Default value: Default | +------------------------+-----------------------------------------------+ | | From the drop-down menu, enable or disable | | | whether Unified CM inserts a trusted relay | | | point (TRP) device with this media endpoint. | | | A Trusted Relay Point (TRP) device designates | | | an MTP or transcoder device that is labeled | | | as Trusted Relay Point. Unified CM places the | | | TRP closest to the associated endpoint device | | | if more than one resource is needed for the | | | endpoint (for example, a transcoder or | | | RSVPAgent). If both TRP and MTP are required | | | for the endpoint, TRP gets used as the | | | required MTP. If both TRP and RSVPAgent are | | | needed for the endpoint, Unified CM first | | | tries to find an RSVPAgent that can also be | | | used as a TRP. If both TRP and transcoder are | | | needed for the endpoint, Unified CM first | | | tries to find a transcoder that is also | | Use Trusted Relay | designated as a TRP. | | Point | | | | Select one of: | | | | | | * Default - The device uses the Use Trusted | | | Relay Point setting from the common | | | device configuration with which this | | | device associates | | | * Off - Disables the use of a TRP with this | | | device. This setting overrides the Use | | | Trusted Relay Point setting in the common | | | device configuration with which this | | | device associates. | | | * On - Enables the use of a TRP with this | | | device. This setting overrides the Use | | | Trusted Relay Point setting in the common | | | device configuration with which this | | | device associates. | | | | | | Default value: Default | +------------------------+-----------------------------------------------+ | | If you use the Cisco Intercompany Media | | | Engine feature, select this check box to | | | indicate that calls made through this trunk | | | might reach the PSTN. Select this check box | | | even if all calls through this trunk device | | PSTN Access | do not reach the PSTN. For example, select | | | this check box for tandem trunks or an H.323 | | | gatekeeper routed trunk if calls might go to | | | the PSTN.

In | | Search Space | this case, the rerouting calling search space | | | that is used is that of the initial SIP user | | | (A). | | | | | | Calling Search Space also applies to 3xx | | | redirection and INVITE with Replaces | | | features. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | Calling search spaces determine the | | | partitions that calling devices can search | | | when they attempt to complete a call. The | | Out-Of-Dialog Refer | out-of-dialog calling search space gets used | | Calling Search Space | when a Unified CM refers a call (B) that is | | | coming into SIP user (A) to a third party (C) | | | when no involvement of SIP user (A) exists. | | | In this case, the system uses the out-of | | | dialog calling search space of SIP user (A). | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | Supported with the Presence feature, the | | | SUBSCRIBE calling search space determines how | | | Unified CM routes presence requests from the | | | device/server/application that connects to | | | the SIP trunk. This setting allows you to | | | apply a calling search space separate from | | | the call-processing search space for presence | | | (SUBSCRIBE) requests for the SIP trunk. | | | | | | From the drop-down menu, choose the SUBSCRIBE | | | calling search space to use for presence | | SUBSCRIBE Calling | requests for the SIP trunk. All calling | | Search Space | search spaces that you configure in Unified | | | CM Administration display in the SUBSCRIBE | | | Calling Search Space drop-down menu. | | | | | | If you do not select a different calling | | | search space for the SIP trunk from the | | | drop-down menu, the SUBSCRIBE calling search | | | space defaults to None. | | | | | | To configure a SUBSCRIBE calling search space | | | specifically for this purpose, configure a | | | calling search space as you do all calling | | | search spaces. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | From the drop-down list box, select the SIP | | SIP Profile \* | profile that is to be used for this SIP | | | trunk. | | | | | | Default value: Standard SIP Profile | +------------------------+-----------------------------------------------+ .. tabularcolumns:: |p{3.5cm}|p{12cm}| +------------------------+-----------------------------------------------+ | Option | Description | +========================+===============================================+ | | Select one of: | | | | | | * No Preference - Unified CM picks the DTMF | | | method to negotiate DTMF, so the call | | | does not require an MTP. If Cisco Unified | | | Communications Manager has no choice but | | | to allocate an MTP (if the **Media | | | Termination Point Required** check box is | | | selected on the **Device Information** tab),| | | SIP trunk negotiates DTMF to RFC2833. | | | * RFC 2833 - Choose this configuration if | | | the preferred DTMF method to be used | | | across the trunk is RFC2833. Unified CM | | | makes every effort to negotiate RFC2833, | | DTMF Signaling Method | regardless of MTP usage. Out of band | | | (OOB) provides the fallback method if the | | | peer endpoint supports it. | | | * OOB and RFC 2833 - Choose this | | | configuration if both out of band and | | | RFC2833 should be used for DTMF. | | | | | | Note: | | | | | | If the peer endpoint supports both out of | | | band and RFC2833, Unified CM negotiates both | | | out-of-band and RFC2833 DTMF methods. As a | | | result, two DTMF events are sent for the same | | | DTMF keypress (one out of band and the other, | | | RFC2833). | | | | | | Default value: No Preference | +------------------------+-----------------------------------------------+ | | From the drop-down menu, choose the script | | | that you want to apply to this trunk. | | | | | Normalization Script | To import another script, on Unified CM go to | | | the SIP Normalization Script Configuration | | | window (Device > Device Settings > SIP | | | Normalization Script), and import a new | | | script file. | | | | | | Default value: None | +------------------------+-----------------------------------------------+ | | Select this check box to enable tracing within| | | the script or clear the check box to disable | | | tracing. When selected, the trace.output API | | | provided to the Lua scripter produces SDI | | | trace. | | Normalization Script - | | | Enable Trace | Note: | | | | | | We recommend that you only enable tracing | | | while debugging a script. Tracing impacts | | | performance and should not be enabled under | | | normal operating conditions. | | | | | | Default value: False (Cleared) | +------------------------+-----------------------------------------------+ | | Enter parameter names and values in the | | | format Param1Name=Param1Value; | | | Param2Name=Param2Value where Param1Name is | | | the name of the first script parameter and | | Script Parameters | Param1Value is the value of the first script | | | parameter. Multiple parameters can be | | | specified by putting semicolon after each | | | name and value pair . Valid values include | | | all characters except equal signs (=), | | | semi-colons (;); and non-printable | | | characters, such as tabs. You can enter a | | | parameter name with no value. | +------------------------+-----------------------------------------------+ | | Enter one of | | | | | | * 0 - None (default) | | Recording Information | | | | * 1 - This trunk connects to a | | | recording-enabled gateway | | | * 2 - This trunk connects to other | | | clusters with recording-enabled gateways | +------------------------+-----------------------------------------------+ .. _geolocation_fields: GeoLocation Tab .................. .. tabularcolumns:: |p{3.5cm}|p{12cm}| +--------------------+--------------------------------------------------+ | Option | Description | +====================+==================================================+ | | From the drop-down list box, choose a | | | geolocation. | | | | | | You can choose the Unspecified geolocation, | | Geolocation | which designates that this device does not | | | associate with a geolocation. | | | | | | On Unified CM, you can also choose a geolocation | | | that has been configured with the System > | | | Geolocation Configuration menu option. | | | | | | Default value: None | +--------------------+--------------------------------------------------+ | | From the drop-down menu, choose a geolocation | | | filter. | | | | | | If you leave the setting, no geolocation | | Geolocation Filter | filter gets applied for this device. | | | | | | On Unified CM, you can also choose a geolocation | | | filter that has been configured with the System | | | > Geolocation Filter menu option. | | | | | | Default value: None | +--------------------+--------------------------------------------------+ | Send Geolocation | Select this check box to send geolocation | | Information | information for this device. | | | | | | Default value: False (Cleared) | +--------------------+--------------------------------------------------+
