[asterisk-users] Dealing with 2 SIP providers

[Mike]

Yeah ok.  That doesn't help.

What I mean is I want a call to go out on ProviderA, UNLESS it's down and
then go to ProviderB.

I want it to ring 30 seconds and then Hangup if nobody has answers.

I DON'T want to dial both, only one or the other.

Like put 15 seconds on each?  It's quite hard to understand what exactly the
requirements are.
