Look in rtp.conf. You
must have the same udp-ports open as the settings in rtp.conf

Okay so it seems like it
was the firewall, someone just suggested that we disable it (On Redhat server)
and it's working fine... so does anyone know clearly what ports (other than
5060) SIP uses for these calls?

SIP sadness
Wow, after getting the O'Reilly book delivered last
week along with two Digium TDM400P's,I'm really getting the hang of this. But
the SIP to SIP issue is still a problem... and it seems silly because
everything else (should have been?) so much harder but is working pretty
flawlessly. Basically I get no audio either way, and it tries to do a
"native bridge" (handoff?)
So when I dial another SIP extension, I get:
