[SR-Users] Kamailio weighted dispatch problems

[Jasen Hall]

Thanks for the reply, Henning.

I have tried an embarrassing variety of weights thinking I was
misinterpreting the instructions. I've tried weight divisions of: 1/3,
10/30, 90/9, 90/10,100/0, 90/30, and more; all with the hopes of generating
any variance in a straight split of the traffic. In every case I get an
almost equal split of calls dispatched.
