Hi Stefan & Juha,
I did some research and found that response codes 180 until 183 may
include an SDP for early media. Although it's rare in the case of 181
and 182.
I think it's safe to check if there's a body in the reply and the
response code is between 180 and 183 to relay the invite.
Forget my question regarding SDP's in 4xx/5xx/6xx responses. I thought
of that myself the second I pressed the send button... too late...
Best regards,
Tom

i'm not stefan, but i have seen many pstn gws especially that include
sdp in 180 and/or 183. regarding error responses, i don't see a point
why someone would include sdp in them (because the call gets cleared
anyway).
