[Asterisk-Dev] SIP rx issues

[Ben Kramer]

Hiya,

I have been working on the chan_vpb.c channel driver and was testing the
SIP functionality. What I discovered was that I was not able to get in
audio from the SIP phone, but I could hear the other party. Just to
confuse matters this didnt happen all the time.
To confirm it was a SIP issue, I made a SIP->SIP call via asterisk. I
had no audio path what so ever. I then tested the two phones, directly,
and it worked fine.
I am basicly new to SIP to any ideas/pointers would be appreciated. I
have looked through the last couple of months of the mailing list
archives and cant find any mention of my issues. I am using the latest
development branch of Asterisk CVS.

Cheers,

Ben.
