Hi Samira,

you could use a SIP library like pjlib to create your testing scenario. But if 
you simply want to determine the overhead, then you could also estimate or 
calculate this easily, at least for the traffic overhead. The run-time 
overhead could also be roughly estimated.

Simulation or a real implementation is of course more acurate, but also much 
more work..

cheers,
