Lingo uses Level3 Communications, and as far as porting goes, so long as
the number is a primary number on an account there shouldn't ever be an
issue. If a VoIP service really wanted to get technical then they would
bring up the fact that there are no TRUE phone numbers on a VoIP service
so nothing is ever portable. As far as the backend servers are
concerned, your SIP username is your phone number and the rest are
virtual numbers on your account.
Regardless, Lingo to Vonage works, Vonage to Lingo works, I've seen
porting take place all over the spectrum. Just remember that a
successful port can take over a month to complete successfully. If
you're not willing to wait that long, or to risk the possibility of the
port being turned down, then I wouldn't bother.
