Hi,

Figured this out. Seems I had made a mistake in the names of AVPs. Changed the AVP names as the exact names used in the example contained in dispatcher doc. Dispatcher started to work, I can see even distribution of loads to 2 Asterisk servers. Will verify if maxload is being enforced or not, not really an issue even if it is not enforced.

Thanks,

Hi, Daniel

I just tested the dispatcher in 4.3.1. It showed the same behavior as 4.2.3. All the calls are sent to one Asterisk (the last one in the dispatcher list), the maxload setting in dispatcher table is ignored.

We use db dispatcher table instead of dispatcher list file, and the kamailio.cfg is the same as included in the previous email in this thread.

Hope I didn't make any mistake in kamailio.cfg.

Thanks

Yes, 4.3 should have all fixes in 4.2.

OK, we’ll try to update and report back. Wonder if the latest 4.3 has all the fixes went into the latest 4.2.x. We already have plan to upgrade to 4.3.

Thanks.

It was a fix for maxload during 4.2.x, but don't recall exactly when was backported. Can you upgrade to latest 4.2.x and see the results? Your config file and database don't require any change, only deploy the binaries for latest 4.2.x and restart.

If the issue is still there with latest 4.2.x, report here and I will look at it with the first chance.

I'm trying to set up kamailio dispatcher to distribute calls to 2 asterisk servers. So far, the failover case seems ok, but I cannot get the dispatcher to distribute load. All calls are going to the last destination entry in the dispatcher table even if I have set the maxload attributes. I'm using algorithm 10 for load distribution. The number of calls sent to one asterisk is well above the maxload. Hope someone more experienced in dispatcher can review my config and give me some recommendations. Thanks in advance.

Here is the content of dispatcher table in postgresql db.

select * from dispatcher;
