Hi,
I personally think that there needs to be an official wiki page giving
details about a basic redundant/HA server setup. A lot of people need this
on regular basis. So I request forum members and contributors to share
their guidelines on this.
Thanks,
Sammy Go.

Hi Carel,
this is a rather complex question with no simple yes or no answer.
You can use the dialog module with no "in-memory" storage of dialog
data and leave it to the database to do the replication. I think
postgres has Multi-Master Replication, i am not sure about MySQL.
At a major german telco operator, we did something similar: We had two
servers, both with different addresses and an Alias for the other
server. In that case, we had two loadbalancers (logically one in a HA
setup) in front, who would do the failover in case. Worked fine.

Dear all, hope to get some information from you
guys!
For a redundant service we have to build up SIP proxy/registrar server
in a
high available scenario. Therefore, we will have
2 SIP proxy/registrar on
two completely independent servers. They should be SIP dialog stateful
and
replicate all the session/call states between
each other. If one server
fails, the other should have all the SIP dialog information for call
handling and accounting. How can this done in a stable and reliable way?
Is
this feature mature enough to support enterprise
requirements?
The only information I have is to build it up with the DISPATCHER module,
but it seems more to be a stateless load-balancer instead of a HA module.
Who has experience with HA failover designs with Kamailio and can give me
some hints?
Thank you very much in advance
Kind regards
