I am trying to switch my Cisco CME from Pots lines to a SIP Trunk from Broadvox. After some trial and error I am able to make and receive calls with excellent two way audio. Broadvox is saying that they are receiving register messages from the phones themselves and not just the CME.
CSeq: 2371 REGISTER
I had previously had trouble with one way audio, inside phones could hear outside phone audio but not the other direction. I was able to acheive two way audio by removing:
bind control source-interface GigabitEthernet0/0.10
bind media source-interface GigabitEthernet0/0.10
I am also having a problem now that I can no longer reach my Exchange 2010 UM on extensions 800 or 801 ip 10.10.10.10.
Am I binding SIP incorrectly? Do I need to configure a loopback and bind to that?
