Do you mean VOIP lines as in "numbers my customers can call to get to me" or 
VOIP lines as in "multiple providers I can call out through" ?

If it's the former, you have to work with the origination provider(s) to see 
if they can provide a "rollover" or "hunt" or "equivalence" or "ringdown" 
across the numbers.  All of those terms are roughly equivalent, it just 
depends on who you talk to as to what term they understand.  However, I doubt 
very much you'll have much luck getting them to provide such service unless 
they're from the same provider.

If it's the latter, you can use plain old extension logic to Dial out one and, 
if it can't complete, fail over to the next.

Sounds like the former.  Good luck.  :-)
