Hey List I sometimes use our asterisk server to do some debugging or other PBX and SBC.
Now we have a case where a PBX is replying an incomming invite with 180 ringing immediately. It looks like the SBC does not accept this. According to my understanding of the RFC 3261 any provisional (aka 1XX) reply should be good enough to make the sender stop re-sending invites and accept this as a reply from the destination. So 100 trying would be option and a reply could also be directly 180 ringing. So maybe some RFC specialist could tell me how this is exactly supposed to work of if I maybe missed some other RFC more clear about that topic. To try to reproduce the problem with our SBC, is there a way to tell the asterisk, preferably PJSIP, to directly answer with 180 ringing without prior 100 trying?
