--------------------------------------------------------------------

Asterisk isn't a SIP proxy and isn't simply moving around messages, so even without media there is a substantial cost to setting up and handling calls. If you need high capacity SIP routing then a SIP proxy would be a MUCH better fit as that is what they are designed for.

The code will predictably distribute calls to threads, depending on the contents of the SIP request it can cause the calls to end up over a few threads.

If you still want to use Asterisk you'd need to do profiling, understand the bottleneck, see if there are ways to improve it.

> Hi,
> Using sipp I run loadtests on Asterisk and I observe If I send 10 calls per second Monitor_thread and pjsip Threadpool(with 200 threads) can handles calls with 30second duration long. But say if I send 50 calls per second using sipp to Asterik I observe monitor_thread can handle it without problem but threadpool cant: I see as monitor_thread processed 1000 calls (new INVITE) while threadpool only processed around 300 calls(New INVITE) and rest are ignored
> I will appreciate if you can help
> Regards
