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
