[OpenSIPS-Users] Transfer issue

[Bogdan-Andrei Iancu]

Hi Iñaki,

Actually this is why the B2BUA module was designed in opensips - in most 
of the cases you need to control/change the dialog(s) but without any 
media dependencies/penalties (like you have now in most of the IP-PBXs).

So you actually can have a highly scalable signalling B2BUA - the 
opensips module could be used to locally (on opensips) interpret the 
REFER and do the call transfer, totally transparent to the other party.

Regards,
Bogdan
