[OpenSIPS-Users] Transfer issue

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.

Thanks,

Jeff

Hello flavio, thank you for your response.

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
