prting from 1 voip to another

At any given moment it is Not possible to port from ANY provider to ANY provider. It is possible to port form MOST providers to MOST providers at any time. Ask the one you are thinking of moving to what they can do, then check with 'usenet' to see what the experience has been. I could tell you my horror story - but I won't!-)

For one datapoint, I ported my Vonage number to Lingo last month with no trouble at all. It took about a week. The underlying carriers are Paetec for Vonage and ACC National for Lingo.

Perhaps if Vonage had noticed they would have objected, but since they've ignored all my attempts to communicate with them in the past three months (which is why I dumped them), I'm not surprised.

Some providers support number portability... but I heard it's a hassle at the moment - numbers can take months to get transferred.

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.
