I noticed the exact same behaviour with my implementation, even though the priority and rweight are different.

until now, i'm ignoring the "issue". But if there is a fix, I would like to know too.

Hello all!

We are running Kamailio version 5.3.3 with 16 small Asterisk servers. Kamailio uses a dispatcher module to distribute calls. Algorithm #11 is selected. All destinations are configured with priority set to 50 and attribute to rweight=50.

We noticed that one server constantly receives more calls than others. I run a few tests. I was sending 1000 calls to the system. 4 per second. All servers except one were getting around 60 calls while the last one - around 100.

I then noticed that the server which receives most calls is always last in the "kamcmd dispatcher.list" command output. I then changed the order in the dispatcher DB table and repeat the test. The other server that now was last was getting the most calls.

Does anyone else use algorithm #11 and finds the same thing? Is there something additional that I can provide to help with the investigation?

Thanks!
