[OpenSIPS-Users] REFER erroneous retransmissions

[Damien Sandras]

Dear all,


We are using opensips TRUNK together with Asterisk. Some requests like 
PUBLISH, SUBSCRIBE, MESSAGE are directly routed between peers but normal 
calls are still routed through Asterisk (that is a temporary solution).

However, we noticed that even though a REFER sent by a phone has been 
accepted by Asterisk (202 Accepted) and a NOTIFY has been sent, OpenSIPs 
tries retransmitting the exact same REFER after T1_Timer like if it had 
not been accepted by the remote endpoint. This is the only request for 
which it happens and I don't understand why.

Is there something we are missing ? What can I check ?

The wireshark capture is here :

Can somebody help ?

Thank you,
