[Serusers] Running multiple instances of rtpproxy? How to set up in SER?

[Frank Durda IV]

I have reached the point where a single instance of
rtpproxy is about maxed-out, showing that its single
process is comsuming 85% or so and climbing of the CPU
available.   That works out to about 600 standing
calls, the bulk of which are G.711.

This is a multi-processor/core system and I have several
other CPUs not really doing anything, so I would like to
start up multiple instances of rtpproxy, which rtpproxy
says it can do, controlling them via AF_INET sockets
instead of the default AF_UNIX.

How you set up rtpproxy for multiple instances seems
reasonably straightforward, but what you do on the SER
side to let it know that these additional copies of
rtpproxy exist and how you or SER divides call load
between them is less clear.

Is there any documentation or examples showing this
done, or better still, someone with a working ser.ctl
file who would be willing to show at least that part
of their configuration?

Ideally, I'm looking for a case where calls are
divided among rtpproxies regardless of where they
came from or where they are going, as I have one
particular call source/destination pair that is
absurdly large compared to all others, and that so
it in particular has to be distributed across
across multiple rtpproxies.

Thanks in advance!
