Hi.
Could you some explain about interaction between original INVITE transaction
and b2b top hiding's transaction?
They are different transactions. The first one is not forwarded and is
replied by the server. And the second one is created by the server and
replied by a client.
As I see that b2b transmits all sip packets to the original INVITE
transaction via loopback interface.
And in the failure situation in the B2B transaction my failure route was
calling. But failure route wasn't calling in the original transaction. Why?
Failure route is called when a negative reply is received. For the first
transaction no reply is received - OpenSIPS is the one generating the
replies.
To have this functionality you should either loop the request once
before calling b2b_init_request or have another openSIPS instance in front.
