[Asterisk-Users] How to use multiple VOIP provider trunks

[Chris Mason]

I have been able to setup three different providers successfully, but only
one at a time. I would like to have all active in a fail over configuration
so that one failing would not be noticed by the users. I know it's probably
easy to configure but I have not been able to find out how. Can anyone give
me an example?
