I think that's yet another issue (which then reinstatiates itself in some other issue)

you must have a loop in your script which you have to fix first. Just ngrep loopback
interface
to verify this is the cause of the problem.

I think ser should remember canceled transactions
and send CANCEL in
case of delayed provisional replies.
At present I don't think its working like this, As soon as CANCEL hit SER an immediate
too many hops is returned to sender and call continues....resulting in ghost call, where A
party has dropped after sending cancel and B still carries on as no cancel was sent to B.

Hi ,
I tried to call from one nokia sip (E61 and other models )phone to another nokia sip
phone. The call works fine. The problem comes only when I call from Phone A to Phone B and
then immediately cancel the call(from Phone A). The Phone A will hangup the call as it
sent CANCEL but the SER will ignore this CANCEL and still send INVITE to Phone B resulting
in a ghost call situation.

I tried to capture a log of message and found
that Phone A "CANCEL" message is received on SER even before any provisional
response from Phone B. Therefor SER doesnot relay this CANCEL request to Phone B. I even
checked RFC which clearly says that UAC should not send CANCEL untill it receives any
provisional response. I talked to Nokia expert and they said the 100 Trying message from
your server is considered as provisional response, therefor behaviour of client is
absolutely correct.
Is there any way I can stop 100 Trying message and still run statefull SER, so that I can
verify what nokia said. Any ideas suggestions are welcome.
Thanking you all in advance.
