Thanks for this advice. I didn't see any clear instructions on the web about 
how to do this.

My intent is to use multiple rtpproxies on the same IPs, so I will partition 
the RTP port range as suggested.

Hello William,

In 2.0 there are indeed multiple threads, but as worker (doing the RTP relay) 
is still one. The rest of the treads are light processing ones. So I would keep 
a one to one mapping, IMHO.

If multiple rtpproxies are using the IP for RTP relay, then you have to 
partition the port rage to avoid overlapping between them. If there are 
different IPs, you do not need to do this.

I am using multi-core processors (who isn't) and want to get the most out of 
opensips + rtpproxy running on the same server.

According to opensips docs I can tell opensips to load balance between two 
instances of rtpproxy on the same machine, controlled through different UDP 
sockets:

(From http://www.opensips.org/html/docs/modules/2.2.x/rtpproxy.html)

# multiple rtproxies for LB
modparam("rtpproxy", "rtpproxy_sock",
"udp:localhost:12221 udp:localhost:12222")


Using rtpproxy 2.0 it looks like I should have two cores per rtpproxy. Is it 
enough then to set up (CORES / 2) instances of rtpproxy, each with the same 
parameters on the server but different control sockets, and then tell opensips 
about them using the rtpproxy load balance syntax shown above?

Do they need to be assigned different RTP ranges, IP addresses or anything like 
that? I have set up a test box as I just described but cannot tell whether I 
will have resource conflicts under load.
