Hi YinLin,

Well, for opensips, the cps (calls per second) is the most relevant 
param. And the value is higly depending on the complexity of the 
configuration/routing script.

You can do a simple SBC for NAT, but also you can do (as have recently 
implemented) and SBC with TLS, NAT traversal, disaptching and failover 
between servers, topology hiding, redirect handling, etc....

So, it is hard to give a number without having the script itself.
