Currently i'm investigating SIP using
resiprocate library.
And i'm stuck at such problem.
User A send INVITE to User B.
After that A sends CANCEL and , like
RFC sais i've no effect ,so call remains established on the User B side.
What is the way to "fix" this
problem?
Currently if A try to send CANCEL in
trying state I send BYE...Am I doing right?
I found couple of thougths about this
problem in resiprocate-devel mailing list ,but there os no specifically
decision.
Deeply appreciate for attention.
