Hi Bansal,

Jan Janak just published some research about the performance of
the version 3.0 - it contains some numbers:

With regards to an exact BHCA number, this depends a lot on your configuration
complexity, your database setup, logging and DNS speed etc..

In my experience usually Kamailio/ SER is not the bottleneck, normally you've
bigger issues (in certain overload situations) getting the calls to the PSTN network
through your gateways.

Best regards,

Henning
