Sir , I always do a thorough searching through the user's mailing list here., and I know I still find it difficult thinking about creating a cluster of Kamailio servers. If only there could be basic instructions and specially role of new version modules(may be *dmq*) to create a telco-grade implementation would be a great resource.
Thats just my suggestion, I am trying to setup a clustered service and still no luck. Only heartbeat works which is pretty basic, anything on top of heartbeat to make it application level redundant (active/passive OR active/active) like OCF resources and their documentation is never published or documented by anyone so far !
Thanks Sammy Go.

Hello,
the wiki is open for everyone to contribute:
You need to make yourself an account, the anonymous posting based on CAPTCHA was disabled due to spam bots easily breaking CAPTCHA system and posting spam.
If someone takes the time to search a bit through the archive, probably can find useful information to add to such page, then perhaps other people will come and contribute more.
The mailing list is full of useful information, the problem is that not many people are digesting it and write wiki pages ... most of the content is by core developers, but they have other tasks as well, so a hand from user community will be more useful.
Cheers, Daniel

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
