Actually if you want to know how many concurrent calls any SIP server can handle then SIPp is a great tool. No matter how SIPp makes calls (parallel/sequentially) the calls have a duration defined in your script. and SIPp keeps on sending calls so they all are active for kamailio.

So increase the call rate from SIPp and SIPp will start delivering 100 CallsPerSecond or N-cps, thats exactly what you want to find out. If you've one good server then you can change SIPp command parameters and only one machine can have like 2 or more SIPp generating calls in parallel.

Hi,

I want to test kamailio or any other server for it's simultaneous call rates, form which I mean how much calls it can support simultaneously??
I know about SIPp, but that won't fulfill my purpose, because SIPp doesn't offer simultaneity; rather it issues calls serially.

BTW, is it possible to do multiple calls from same machine, since ports are consumed in the previous call?? I think the answer is negative....

I think, to do this kind of testing, we need multiple PCs..which call simultaneously...

Any light on this??
