The neighbor is directly across the street and also has a number that was a Sprint number before Vonage ported it. Others in my immediate neighborhood have been ported from Sprint (a.k.a. Carolina Telephone) to Time Warner's voip service.
[TELECOM Digest Editor's Note: Maybe you should bring this up again with the Lingo service rep. What, exactly, makes _your_ number different from theirs? A different (and perhaps less well equipped exchange) perhaps? PAT]
