[Kamailio-Users] Load Based Load Balancing

[Ovidiu Sas]

Please keep the list in your replies.
Check the dialog documentation carefully.  It is all explained there:
how to add dialogs into a profile and retrieve the them.
The dialog profiles are stored into memory for fast access.

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.
