Hi Daniel,

Just a query regarding the same. I will be building 2 live kamailio servers based in 2 different countries which will be a backend to a mobile app. I already have a test server running fine. I need to know how to have 2 kamailio servers relay calls to each other, could you specify the below if applicable in my case. What is the specific config I need to do which will be different from hosting just one Kamailio server. Please note I am not using domains or dns but IP addresses, for example user01@111.111.111.111. I have also suppress reverse lookups in config file.

Regards,

Neville

Hello,

if the domains are in DNS, then simply relay (e.g., using t_relay()) from each instance. Kamailio does dns query and will send it to the other one.

Hi Kelvin,

Thanks for your valuable response. I hope you don't mind me asking the specifics here I am pretty much a newbie. Do you mean the below code in kamailio.cfg file or is it something else.

route[RELAY] {

# enable additional event routes for forwarded requests

# - serial forking, RTP relaying handling, a.s.o.

if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) {

if(!t_is_set("branch_route")) t_on_branch("MANAGE_BRANCH");

}

if (is_method("INVITE|SUBSCRIBE|UPDATE")) {

if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY");

}

if (is_method("INVITE")) {

if(!t_is_set("failure_route")) t_on_failure("MANAGE_FAILURE");

}

if (!t_relay()) {

sl_reply_error();

}

exit;

}

Also do I need to specify my 2 IP addresses on the both kamailio servers ? and how do I edit this, I mean the syntax. It would be great if you could give me a an example.

Regards

Neville

it is still the same t_relay() for both IP address or domain name.

I think you need to play with the base configuration. If you place a call to "user01@111.111.111.111" with the default configuration it will just work (TM).

Just change the domain part of the URI if needed, then relay. Kamailio will take care of the rest. If you don't want to change the domain part of the URI, you can change the $du pseudo-variable before you relay.

Relaying can be done statelessly with the forward* family of functions and statefully with functions in the t_relay* family in the TM module.

Have fun!
