[Asterisk-Users] ip2ip 302 response

[Jan Baggen]

I have 2610 XM with 1 Fastethernet and VIC2-2BRI. Dialin and dialout over 
pstn is ok. Also inbound pstn calls get redirected to Asterisk y.y.y.y  

But I want to setup VOIP sessions with local carrier. I added dial-peer 
40 for this and enabled ip2ip on this peer. Calls will get routed trough
this peer but the remote sip server is never contacted (no activity with
tcpdump) 

My situation:
PSTN -> CISCO -> ASTERISK  OK
ASTERISK -> CISCO -> PSTN  OK
ASTERISK -> CISCO -> VOIP  NOT OK (Got SIP response 302 "Moved Temporarily")
