tectops module with search is the only way to get the User-Agent in SER version 0.9.x
If you're using newer versions you can use select framework to get the value of any (?) header of the incoming SIP request.

Hi,
Thanx for the tip, I found the file and will try this way.Is there any way we can get user agent value inside the script, so that i can put some check for it and decide whether to send 100 or not.
Thanks Abdul Qadir

After that, you should send back from your config file the 100 Trying response in the convenient places to stop retransmissions.

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.
Best Regards, Abdul Qadir
