[asterisk-users] "remote" SIP, no audio, or one way audio.

[dave cantera]

joe,
when I have problems with audio and other connections seem to work, I 
always look for a codec incompatibility...  use  'sip set debug peer 
<extension>'  and look for the codec handshaking... make sure both 
extensions have a compatible codec choice...
