Did anyone managed to get SIP REFER to work in combination
with sippy b2bua? The scenario is like this:
SIP_UA01 ----> SER01 ----> sippy B2BUA01 ----> SER01
----> SIP_UA02 ----> SER01 ----> sippy B2BUA01 ----> SER01 ---->
So then SIP_UA02 decides to transfer call from SIP_UA01 to
SIP_UA02 ----> REFER SIP_UA01 ----> SER01 ---->
sippy B2BUA01 ----> SER01 ----> SIP_UA03
The problem is that sippy says 202 Accepted, and sends BYE
to SIP_UA02, which is good and then it sends REFER to SIP_UA01 which then does
INVITE, so I have two calls on SIP_UA03.
I think that sippy is broken here, but ain't sure, and I constantly
try to get on users or dev list on b2bua.org but I never receive confirmation
of any kind?
Sorry if this is sippy problem but didn't know where to turn
for help, and confirmation would be good to have.
