You can do the tuning according to your requirement.

But i think there is a better way to increase the calls to the sip server.

To increase the calls to sip server means to maximize the run-time of sip
server process.

This can be done by increasing the nice value of that process, with the
"renice"  command. Only root user can specify the negative values. I think
this should do the job.
