[OpenSIPS-Users] B2B top hiding not processing BYE correctly

[Anca Vamanu]

Hi Henk,

The reason is that the RURI for the first BYE does not match the contact 
that OpenSIPS B2BUA put in 200Ok:

U 2011/01/02 03:23:25.592645 10.190.0.1:5061 ->  10.135.59.244:5060

Here is the section in RFC that says the RURI must match the contact:

12.2.1.1 Generating the Request

    "If the route set is empty, the UAC MUST place the remote target URI
    into the Request-URI."
