[Asterisk-Users] chan_sip, nat, no media before 200 OK

[Michael Koehler]

My * box is behind NAT and works well. The only issue is that when i 
make a outbound call i get no media with "183 Session progress" w/sdp 
before the session is setted up with sipmsg "200 OK/ACK"

The pstn gateway is a AS5300 and it runs the newest image. Media address 
detection is enabled on the AS and when i'm passing the asterisk by and 
use the proxy instead of the asterisk then it works fine. I tinkered 
with the Dial() application flags already w/o positive results.

2 Questions:

Is there anything else i have to set up at sip.conf.

Are SIP call flowcharts available for chan_sip ?
