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