CUCM-> VCS->VCS Express

Hello,

 

I want to understand the call flow from CUCM to VCS to VCS-express and vice versa.  Like to make a video call from Cisco IP Phone to endpoint out of the organization, the call flow will be as the following:

From the IP Phone dial: abc@external.com

The address will match SIP Route Pattern *@external.com  to SIP trunk to VCS. In VCS search rule to traversal zone … etc.

 

 

Please help me to complete the call flow and correct me if I am wrong.

 

Thanks,

That is the correct call flow

That is the correct call flow. You will have a SIP trunk from CUCM to VCS IP and also zones and search rules on the VCS to call back.
