[SR-Users] High availability design with Kamailio

[SamyGo]

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.
