  bind control source-interface GigabitEthernet0/0/0
  bind media source-interface GigabitEthernet0/0/0


  *   Tried to bind it to the dial-peer as well

No response from carrier

IP is for outbound Invite is my public IP configured on gi0/0/0

What does your SIP bind config look like?  What IP addresses do you see in the 1XX response from the carrier?  What is the IP in the Contact header for the outbound invite?

Hey guys,

Ran out of options. I have a new CUBE deployment to Bandwidth.com<http://Bandwidth.com> SIP provider and I see the SDP invites going out the egress interface and running a monitor capture on the CUBE, I see the return 1xx responses but still not seeing them on the debug messages. So, CUCM sends a CANCEL after not receiving any reply’s from the CUBE. The kicker is the call still connects. Any help at this point will be great.


Thanks,
Ben
