Thanks Lori, that's exactly what I was looking for.

We're looking into VoIP choice for a small office.  If we decide we 
don't need an auto-attendant, extensions and all that hoopla, would it 
be possible to each have a DID from an ITSP?  That is, can you have 
multiple SIP devices (softphones, probably) behind NAT, each of which 
have their own DID?
