Asterisk doesnt seem to send 180 ringing with SDP information. it does it with 200 OK.

How/What to configure to enable Asterisk to send the SDP that it send with 180 OK instead of 200 OK ?

TIA.

Yes, Asterisk doesn’t send SDP with 180 Ringing. And this is what Asterisk has to do 🙂  
The only one provisional response (1xx) which could contain SDP is 183 Session progress. And Asterisk sends it…

Hope this helps.
