[SR-Users] RTPProxy with kamailio : How to get calls count?

[Mino Haluz]

CPU E5504 Xeon 4MB cache 2GHz
800 concurrent calls with 92% CPU usage
So 400-450 calls for 1GHz (with 99% CPU usage, in fact I cannot get it
to 100% dunno why)

They had 325 calls per 1GHz, so yes, there must be some improvement ;)
