Yes it would tie you to ourselves as a customer, we offer a 99% SLA
that numbers we supply are reachable from the PSTN both domestic and
international networks at all times.

And of course your free to use any VoIP/ITSP you want, swap and change
as many times as you like, without losing the number, somewhat like
number porting, simply use our control panel and make the change, and
within a matter of seconds the number is updated to your new
destination.
