That would require transaction replication, which Kamailio doesn't have.
Most messages can be processed statelessly, so this isn't a huge obstacle. However,
CANCELs won't work.

Hi all!
I am having some difficulties/doubts on what would be the best approach to let multiple
Kamailio servers share their SIP sessions between each other.
The goal is to have HA on Kamailio cluster such that if a call is received and initiated
on Kamailio #1, and during any moment of the call (before or while established) if the
server #1 goes down or Kamailio stops working for any reason, the call can be processed by
Kamailio server #n available in the cluster.
I do not want to mess with Virtual IPs or DNS, that is not the point, but instead need to
get a proper way to share SIP sessions between Kamailio servers such that any server could
continue the call without issue.
I have checked the Dialog and DMQ module, but I am not sure if that is the way to go....
Could any one share a solution for this?
Greatly appreciated.
Cheers,
