A quick question,

What is the best way to limit the rate of the kamailio,

Say I want it to process only 200 INVITEs per second

I know this can be done using ratelimit module, but what if I want to change this rate dynamically? say, in an overload control scenario, I am getting a recommended rate piggybacked in my replies, and I read it, then how can I change the messge processing rate of kamailio in runtime inside my script?

Is there a way to change the rate using ratelimit but inside script as messages come? 

The RPC function (rl.set_pipe) does it, but can I call it inside my script?

Thanks,

Alireza
