Simplest thing to do would be to use 'dispatcher' with round-robin strategy and enter the servers in the table or list file in duplicate, in proportion to the weight allocation they have.

Also the carrierroute module has this capability.

Hello,

I have setup 3 SIP server. It should be Kamailio, Asterisk or Any SIP Server.

I have setup 3 server say Server A, Server B and Server C and each has weight like 50, 30, 20 in percentage.

And I taken 10 calls and try to forward call based on weight.

Is this possible in kamailio's module.. and if yes then which module will help me?

Any Idea..

just to note here that the devel version of dispatcher has dedicated weight-based load balancing algorithm - of course, will be available as stable with next major release - 3.1.0.

Good to know - thanks!

Hi

Thanks for reply.

I have look into carrierroute module, it seems that my requirement is fulfill.

But i have multiple carrier in my carrier_name table, say car1, car2, car3, default, and I want them load dynamically on INVITE of any user based on its probability. Above all carrier has 0.1 probability and each point to different asterisk machine.

How could it be possible..??

Any Idea..?

Hello,

I think you can do things much simpler . For example you don't event need a database, you could use carrierroute in file mode . Just have one sp-route.conf file containing the entries like in this example:

domain my_domain { prefix NULL { max_targets = 10 target asterisk_server1:5060 { prob = 0.1 hash_index = 1 status = 1 comment = "asterisk server 1" } target asterisk_server2:5060 { prob = 0.1 hash_index = 2 status = 1 comment = "aserisk server 2" } ..... } }

Then in the cfg file you could specify modparam("carrierroute", "config_file", "/path/to/sp-route.conf")

To balance INVITEs, in you cfg you call

if(method == "INVITE"){ cr_route("default", "my_domain", "$rU", "$rU", "call_id"); forward(); }

This will balance your invites based on the Call-id header.(it will be sent randomly to one of the hosts based on the weight). If you want you could balance them based on from_user(Call originating from one user will always go to the same asterisk machine). Note that in file mode you only have 1 carrier(called default), but you can have several domains.

Hope this helps Marius
