[OpenSIPS-Users] rtpengine sets - load balancing proxy weighting

Hey Mark,

The load balancing weights are set on a per node basis via their socket 
URL. If no weight is explicitly set, then the default is 1.

schema:
<proto>:<ip>:<port>(=<weight>)

ex:
udp:192.168.1.200:22222=25

There currently is no way to dynamically change the weight of a node, 
although there's an open PR [1] which would allow for weights to be 
changed via the "rtpengine_enable" MI command.

Thanks,
John Burke
