[Kamailio-Users] Load Based Load Balancing

[Ovidiu Sas]

Hello Kareem,

Use dialog profiling to track the number of calls per destination:
http://www.kamailio.net/docs/modules/1.5.x/dialog#id2531102
In your script, before sending the INVITE out, check if the selected
destination has enough capacity to accept the call:

How would I be able to route calls to the box that's least used - in this example, "FreeSWITCH 2" at any given time had the least number of calls, so calls 4,5, and 6 were dispatched to it.
