[Asterisk-Users] No audio when calling between internal phones

[Tom Hayden]

I encountered a similar problem with CVS-HEAD and sip2sip calls
between our Polycom IP500s.  I attempted to diagnose the problem and
there are a few patches on mantis, but none of them worked for me.  I
flipped back to stable and have had no problems since.

Anyone got any ideas?
