CME to CUCM SIP Trunk. Incoming Calls

Hi All,

I am currently working on a new CME integration (my first one) and want to ensure I am on the right path.

I have a SIP Trunk running from CME to CUCM and OUTGOING calls are working fine. I have not added any INCOMING dial-peers (or any other configuration). Was looking for some help getting the basics going for this part of the config.

This is a very basic configuration and will not use any PSTN connections (only 4 digit through SIP to CUCM.

Here is what I have so far.

CME to CUCM SIP Trunk. Incoming Calls

Yup, that would be next thing to check. You can add the IPs there, disable it completely or add dial-peer with destination pattern of CUCM server.

For troubleshotting use "debug ccsip messages".

If you don't add any dial-peers default dial peer 0 will be used for incoming calls, the only thing to keep in mind about default dial peer is that it will use G711 codec. You can modify your existing dial peer as following to use it for inbound as well:

dial-peer voice 101 voip

incoming caller-number .
