Support for Software Media Termination Point
The Support for Software Media Termination Point (MTP) feature bridges the media streams between two connections allowing Cisco Unified Communications Manager (Cisco UCM) to relay calls that are routed through SIP or H.323 endpoints via Skinny Call Control Protocol (SCCP) commands. These commands allow Cisco UCM to establish an MTP for call signaling.
Information About Support for Software Media Termination Point
This feature extends the software MTP support to the Cisco Unified Border Element (Enterprise). Software MTP is an essential component of large-scale deployments of Cisco UCM. This feature enables new capabilities so that the Cisco UBE can function as an Enterprise Edge Cisco Session Border Controller for large-scale deployments that are moving to SIP trunking.
How to Configure Support for Software Media Termination Point
This section how to configure the Support for Software Media Termination Point feature.
Prerequisites
•
For the software MTP to function properly, codec and packetization must be configured the same way on both in call legs and out call legs.
Cisco Unified Border Element (Enterprise)
•
Cisco IOS XE Release 2.6 or a later release must be installed and running on your Cisco ASR 1000 Series Router.
Restrictions
•
RSVP Agent is not supported in software MTP.
•
Hardware MTP for repacketization is not supported.
•
Call Threshold is not supported for standalone software MTP.
•
Per-call debugging is not supported.

To verify and troubleshoot this feature, use the following show commands:
•
To verify information about SCCP, use the show sccp command:
Router# show sccpSCCP Admin State: UPGateway IP Address: 10.13.40.157, Port Number: 2000IP Precedence: 5User Masked Codec list: NoneCall Manager: 10.13.40.148, Port Number: 2000Priority: N/A, Version: 6.0, Identifier: 1Trustpoint: N/A•
To verify information about the DSPfarm profile, use the show dspfarm profile command:
Router# show dspfarm profile 6Dspfarm Profile ConfigurationProfile ID = 6, Service = MTP, Resource ID = 1Profile Description :Profile Service Mode : Non SecureProfile Admin State : UPProfile Operation State : ACTIVEApplication : SCCP Status : ASSOCIATEDResource Provider : NONE Status : NONENumber of Resource Configured : 100Number of Resource Available : 100Hardware Configured Resources : 0Hardware Available Resources : 0Software Resources : 100Codec ConfigurationCodec : g711ulaw, Maximum Packetization Period : 30•
To display statistics for the SCCP connections, use the show sccp connections command:
Router# show sccp connectionssess_id conn_id stype mode codec ripaddr rport sport16808048 16789079 mtp sendrecv g711u 10.13.40.20 17510 724216808048 16789078 mtp sendrecv g711u 10.13.40.157 6900 18050•
To display information about RTP connections, use the show rtpspi call command:
