no audio

[Anonymous]

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

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

-Mark

I have the same problem, did you solve it ?

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.
