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
Carel
