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.

Thanks!

I still don't know how to do it, but you've put me on the right track. I'm fairly new to Kamailio, so I'm trying to figure out all the syntaxing. I did an SQL query on my FS boxes, and I was able to see the number of dialogs per host.

Is it possible to do something similar with Kamailio - where I store the dialogs in a DB and query it in the dispatcher section of my routes?

If so, would you be able to give me an example syntax of how I'd go about doing so?

Thanks, Kareem

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: http://www.kamailio.net/docs/modules/1.5.x/dialog#id2532103

Hello:

I've been going through your lists and your documentation, and I'm unable to find how you set up load based load balancing.

To further illustrate:

For example, let's say we have the following live calls:1,2,3,4,5,6,7

Round Robin Works Well

+-----+ | SER | +-----+ | | +--------------+ |-------| FreeSWITCH 1 | [Calls 1,3,5,7] | +--------------+ | | +--------------+ |-------| FreeSWITCH 2 | [Calls 2,4,6] +--------------+

But let's say some of the calls end significantly quicker than the others, how can I send calls by their load (current calls, cpu, etc)

For example, let's say we have the following live calls:1,2,3,4,5,6,7 - Let's say calls 4 and 5 lasted about 30 seconds, while the others lasted about 5 minutes. 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.

Load Based Load Balancing

+-----+ | SER | +-----+ | | +--------------+ |-------| FreeSWITCH 1 | [Calls 1,3,7] | +--------------+ | | +--------------+ |-------| FreeSWITCH 2 | [Calls 2,6] +--------------+

Thanks, Kareem
