[Asterisk-Users] Cisco 7940 no audio

[Craig Waddington]

Yes MOH etc work fine for the receiving end, dialing from outside.

I have run X-lite and GS phones on the network on a test machine before
this one, and it worked great. Though I haven't had a chance to see if
they work or not.

I will definatley check my Firewall logs, that's a good point, but the
sipura works.

It seems codec to me, but I have tried many different confs in sip.

With SIP, missing audio is *usually* either a firewall or NAT issue.  
Check firewall logs and make sure that you aren't seeing packets being 
lost.  Do you have more then one 7940?  If so, can they call each 
other?

Also, when people call into your system, do they get audio from 
asterisk?  Does voicemail work?
