Call Manager 5.x - SIP Trunk

Unanswered Question

Hi

I have a remote user who has been registered in the callmanager as SIP Trunk. SIP Trunks registers with CallManager and able to internal calls with SIP trunk and the IP Phones. Call classification specified as On Trunk.


Now for any PSTN breakout, I need SIP trunk to use the callmanager and MGCP Gateway. Is this achieved by creating another route pattern (9.@) with call classification as onnet and pointing to MGCP gateway?


thanks in advance


regards

Sundara

SIP Trunk

Using a SIP trunk to connect to Cisco Unified MeetingPlace Express has some conditions and version dependencies. The following current combinations are supported between Cisco Unified CallManager and Cisco Unified MeetingPlace Express.


Cisco Unified MeetingPlace Express 1.1.1 and Cisco Unified CallManager 5.x


With this combination, a SIP trunk can be defined directly from Cisco Unified CallManager to Cisco Unified MeetingPlace Express. The following design rules apply to this integration:


A separate SIP Security Profile must be created and associated with the SIP trunk to Cisco Unified MeetingPlace Express. This security profile must have the transport set to UDP. The default setting is TCP, which will not work with Cisco Unified MeetingPlace Express.


The SIP trunk configuration must have MTP Required checked and must have MTP resources available. MTPs will be invoked for each call to Cisco Unified MeetingPlace Express for the entire duration of the call. This requirement does not apply to Cisco Unified MeetingPlace Express 1.1.2 and higher.
