Subject: [SR-Users] DMQ and DIALOG<br>
<br>
Hi List!<br>
<br>
I currently have 3 Kamailio's (Version 5.1) in an ACTIVE-ACTIVE-ACTIVE<br>
scenario behind a load balancer all 3 nodes are listening and advertising<br>
the same virtual ip of the load balancer. Im using dmq module together with<br>
dialogue module to sync the state of the dialog to all 3 nodes. Is there a<br>
way or module that i can use to also sync every transaction?<br>
<br>
Problem that im facing right now is that an INVITE will come to Kamailio1<br>
and the 100 TRYING or 183 RINGING or 200OK will go to Kamailio2 and since<br>
Kamailio1 hasn't received a response will retransmit the INVITE. Or is<br>
there a way with dmq to also update the other nodes for responses like 100<br>
,183 or 200 OK so that Kamailio1 knows not to retransmit?<br>
<br>
Maybe im going down the wrong path? :)<br>
<br>
Any assistance would be greatly appreciated<br>
<br>
My config for dmq and dialog:<br>
<br>
#=====================DIALOG====================================<br>
modparam("dialog", "enable_dmq", 1)<br>
<br>
#=====================DMQ=======================================<br>
modparam("dmq", "server_address", "sip:x.x.x.x:5080")<br>
modparam("dmq", "notification_address", "sip:y.y.y.y:5080")<br>
modparam("dmq", "multi_notify", 1)<br>
modparam("dmq", "num_workers", 4)<br>
modparam("dmq", "ping_interval", 30)<br>
<br>
request_route {<br>
<br>
# MANAGE ALL DIALOGS<br>
dlg_manage();<br>
<br>
if(is_method("KDMQ"))<br>
{<br>
dmq_handle_message();<br>
}<br>
<br>
Thanks!<br>
Phillip<br>
