With my VOIP provider, I didn’t quite have to lie.

I generally don’t need my VOIP number when I’m in the US (cell is free here),
so I simply told them “I do not intend to use this number or this service
within the US”.

The first time I sent them a marked-up contract, they contacted me with
questions. The following year, the new version of the contract reflected
my changes to their original wording.

Since then, I’ve been pretty much satisfied with my service from callcentric
and the price is right.
