[Serusers] Record Routing

[KUMAR]

I am using SER 0.9.6 along with MS RTC Client API for the client
application. When I used the line:
if(method!=REGISTER){
   record_route();
}

It caused in a one way communication only in case of audio as well as
in case of in case of instant messaging, a new communication session
had to be established for each message. But when i removed the
record_route() and used sth like:
if(method==ACK){
    t_relay();
}

When my code included both the above code snippets, it never reached
the later: if (method==ACK)...  part.

Can anyone please tell me why when record_route() was switched on, the
control never reached the later part.
Thank you
