[OpenSIPS-Users] SIP Refer

Hi there,

 

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 ----> SIP_UA03

 

So then SIP_UA02 decides to transfer call from SIP_UA01 to SIP_UA03:

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.

 

Best regards,

 

Josip
