Re: [SR-Users] Issue with BYE and $du

14 Dec 2015

Hello,

which one is the IP of Kamailio. There seem to be two server applications.

Also, it is good to get the trace on kamailio server, on both sides of
the call: to caller and to callee.

Cheers,
Daniel

     $du is ordinarily only set when the network and transport-layer
     destination of the request is different to where consuming the
     domain part of the request URI ($ru) would normally take it.

     What's $ru say for the BYE, and is it reachable? Does it match the
     Contact of the dialog party to which it's going? Do other
     end-to-end sequential requests work, e.g. end-to-end ACK for 2xx
     INVITE reply?
