There is no real good way to have failover on your incoming lines.  The best 
I've been able to come up with is to use a DID provider which will allow a 
failure to dial another number, and have that number a DID for a different 
provider.  It's still not perfect, as I am almost positive that most failures 
of origination occur on the VOIP end (getting the call to you), not the TDM 
end (getting the call to the provider).

That's primarily why we use a PRI ourselves, but I have been experimenting 
with it.
