Thanks everyone for the reply,

But my problem is i dont want my REGISTER request to be handled
statefully....it increases CPU and memory utilization....and i am suppsoe
to handle lot of users on this server.

Then it seems theres no solution via configuration parameters..... i think
i need to add some codes somewhere to solve the problem.

the States are as below:

# registration is handled in stateless manner
# every REGISTER request...even if it is retransmission is been seen as
new transaction and as nonce_reuse is not allowed...it creates new
credentials and sends back 401 to phone.
# here i want something to stop.... i want to detect that this register
request is mere retransmission and not a new REGISTER request... and drop
it within some time frame...say cseq_delay time frame.....

Where should i starts roaming in code? can you guide me a bit about it.
