[OpenSIPS-Users] OpenSIPS B2BUA Refer Scenario

[Bogdan-Andrei Iancu]

Hello Rus,

The XML scenario is correct, also the REFER b2b scenario is know to work
- for sure you have some routing issues in our opensips script.

Do you do any routing in local_routing ? Do you have a pcap I can look
over (send it off list) ?
