[OpenSIPS-Users] 180 w/ SDP -> 183

[Jeff Pyle]

Hello,

A small number of my PSTN carriers send 180 Ringing with SDP when inband
ringback is available.  This causes fits in some versions of Asterisk,
sending an SDPless 180 and immediately later a 183 with SDP.  Some UACs
render that very strangely.

How would one go about detecting a 180 with SDP in a reply_route of Opensips
and, in effect, flip it to a 183 with the same SDP?


Thanks,
Jeff
