So, in order to have it working i need 2 realtime asterisk that are in a master-slave setup and have users created in both. Am i correct?

Try to install SNGREP command line application. It greatly helped me to understand what was going on in kamailio. 

Install it in your Kamailio server, and run it. You will then be able to see and understand all SIP requests and responses.

Also, as Daniel said, the SIP requests between client->kamailio->asterisk must be kept the same at all times when trying to register. Additionally, install Asterisk with Realtime module, and share the same SIP users across your asterisk boxes, by the means of a DB. This is the best approach.

Hope this helps,

I experience something really strange when i change the dispatcher list to have the same priority both of the servers. I am getting 401 (unauthorised) to the extensions trying to register. Even though they in asterisk they seem to be registered, the debug shows 401. Not able to call from one extension to the other.

here is the console error:

<--- Transmitting (NAT) to 192.168.0.99:5060 --->

On the other hand if i change the priority to 0 & 1 the servers respectively, then no errors in asterisk console and they can call between each other.

This is really odd.

Ah,

I see the problem, just change list file in following way:

1 sip:192.168.0.100:5080 0 0 maxload=20
1 sip:192.168.0.101:5080 0 0 maxload=20

Hi Aristedis,

Sorry, indeed you have module parameters.

When one asterisk is down what you see when you run:

kamcmd dispatcher.list

i know that there is something wrong, but i can not figure it out. Especially for the modparam settings that Mr Jurijs Ivolga is proposing, I already had them. it is the kamailio.cfg that I originally attached.

Unfortunately I did not manage to find anything in the parameters that will solve the problem as proposed by Villasmil and Semenov. I have given a try on changes but nothing good came up.

Hi Aristeidis,

David is right, first would be good to check the status of the destinations.

In your configuration there are couple of things to have in mind: need to set correct flag param
https://kamailio.org/docs/modules/5.5.x/modules/dispatcher.html#dispatcher.p.flags
select the algorithm used to select the destination (ds_select_dst) and have a faulure_route where the next destination will be tried in case first is down. 

You can find the examples in the module doc.

Cheers,

I have a Kamailio and 2 asterisk servers. All users are created in both of the asterisk servers. I am forwarding the registration to asterisk. The problem is that it is always used on only one server from the list. Even if one goes to shutdown, then there is not any registration sent to the available server. Even if some of the extensions can be seen registered in both of the asterisk's, if the secondary goes down, then there are no services for the phones.

I am attaching the kamailio.cfg. My dispatch list is:

1 sip:192.168.0.100:5080 0 0 maxload=20
2 sip:192.168.0.101:5080 0 0 maxload=20

In both of the asterisk servers i am using sip.conf to create users and s sip trunk for the Kamailio. Nothing special about it.

I am looking to find what is wrong with my config and i cannot loadbalance/failover to the asterisk servers.
