Personally I "run" the PRI my company has.  Incoming is over the PRI, and I do 
have a few VOIP-sourced DIDs that haven't given me any trouble, but they are 
still single-provider (Unlimitel).  

Offhand, the only thing I can think of would be to have your main VOIP DID 
"fail over" to another VOIP DID from another provider.  It's till too 
"disconnected" for me to trust fully though.

That is correct.  Origination providers take a call originated by the PSTN and 
send that call to you.  Termination providers take your calls and terminate 
them to the PSTN.
