no audio
new 3140 SBC router. I have no audio in or out on SIP calls. You can complete calls in and out, but just no audio. How can I troubleshoot to see what I have missed in programming

Re: no audio
can you post your config? Make sure to remove passwords
also if you can post your debug from these commands:
debug sip stack messages
debug voice verbose
debug sip cldu

Re: no audio
Do you have "media-gateway ip primary" in interface config mode on both the interface where your phones are connected and the one to which the SIP server is connected? If not, do that.
