I'd like to be certain I understand from these last few posts regarding this topic-
The suggestion is to use Asterisk 'behind' Opensips, transferring calls to it only when a B2BUA is necessary? I certainly understand not wanting to post a config, but can anyone share a general idea of how this is accomplished? I'm having a hard time picturing how to send Asterisk an out-of-context REFER, while Opensips 'held' the call up to that point. Perhaps I'm over-thinking it.

It makes sence to me, so i have to use asterisk as a gateway infront of opensips, and let it handle outside domains to do stuff like invites/refers.. The parameter your talking about is a Asterisk parameter right? I will look in to this. Thank you for the information, it's a tricky journey into opensips, but i'm getting there :D Flavio Goncalves wrote: > > Hi Peter, > > You need to have support for REFER in all the SIP components, UACs > and Gateways.
