Can do.

Correct, although you can frontend with SER.

> 2. The IP address of the MySQL server is hard coded into the Asterisk config files. In the event of a database failure, Asterisk fails as well. You need to build redundancy into MySQL with a primary and seconday server, and something that can monitor MySQL system, network, and application and then transparently (to Asterisk, because it can't do it itself) switch IP's in the event of failure.

If you use a MySQL cluster, the IP address will; be of the load balancer
which will forward those requests to the MySQL database machines.

Otherwise you can use http://linuxvirtualserver.org/

> 3. Other stuff I can't recollect right now because I am tired.

:) Aren't we all
