[asterisk-users] Multiple servers using realtime

[Mindaugas Kezys]

Users register to (Open)SER which uses same DB as all Asterisk nodes.
Asterisk Realtime engine lets change data in only one database to make
changes global. (Open)SER does load-balancing and fail-over.

You can even put second (Open)SER server in case first dies and use DNS SRV
to make it active.

Database (DB) can be on same machine, but it better should be dedicated to
only DB to serve only queries from all nodes.

Possible to use MySQL Replication and have same DB on all nodes, which will
save some processing power. But it's harder to manage.

There're tools, choice is yours how you use them.

I think the user registers with the SER box. With loadbalancing an
outgoing call can go through different Asterisk boxes:

call #1 --> SER box #1 --> Asterisk box #1 --> destination
call #2 --> SER box #1 --> Asterisk box #2 --> destination
