Best is to use external gateways and configure SER to send calls to an
available server.  You can use multiple instances of SER so you don't have
any single point of failure. 

If you are using T1/E1 boards, configure two identical servers with T1s.
Have your service provider fail over one T1 to the other (one active and one
backup board in a server is a useful configuration). Finally, use phones
with backup registrars.

The problem is then that you have no redundancy in the T1/E1 handling.
In this scenario it's actually not that hard, and you could even use the
redbox pri machine to send the calls to the correct machine.

Let us know if you need some help with this.
