Hello,

I am beginning to front my Asterisk cluster with Kamailio and so far my biggest issue is the complete lack of quick-start-like documentation for this. Is there any place I can get a very simple HA configuration (telling me where the config files are, for starters, is a good thing) for Kamailio with the following features:

(a) Support an arbitrarily large number of Asterisk servers (say, upto 10).
(b) Offload SIP registration to a realtime/mysql DB used by the PBXs.

Please also let me know if I should have to change my Asterisk PBX config in any way for this to happen.

On a very related note, while I appreciate the fact that you need to _really_ understand SIP to configure Kamailio, it should be possible to get this setup by just running a script or GUI. It is difficult to find information on how to load balance multiple PBXs behind Kamailio.

While I haven’t got full configurations - I do have some notes published on things you need to consider
when doing this - especially the offloading of registrations.

An old but still valid presentation (from 2010):

You have a lot of examples in the dispatcher module README that will help you.
