RTP flow through MRA

[himanshu87]

I have a Jabber that is registering via Expressway to CUCM. It is calling a Internal and PSTN phone.

Can someone share some knowledge on:

1. SIP signalling messages and Direction between Jabber and Internal /PSTN phone.

2. RTP flow between Jabber and Endpoint.(in Internal and PSTN call)

I am trying to understand how the signalling and Media will work and how ICE framework will come in picture.

Thanks

The first two images from the MRA configuration guide cover what you're asking.

Call signaling and RTP for non-MRA endpoints or GWs do not change, it's just as in any regular internal call.
