[OpenSIPS-Users] Limit the number of ongoing sessions at an RTP proxy

[Bogdan-Andrei Iancu]

Hi Chen-Che,

The rtpproxy cannot help you with such an algorithm. It knows which rtpp 
are alive, but has no clue on the load.

What you could try is to use rtpproxy in combination with dialog. Put 
each rtpp in a different rtpp set and make each set to correspond to a 
dialog profile - use dialog profiles to keep the load and select the 
rtpp set from script.
