My experience with porting from Vonage has been somewhat of a pain. The port was successful, so calls from all other telcos were fine... but Vonage screwed up twice: 1) First time the reassigned the number internally to another customer. So all calls originating from Vonage ended up at that customers phone, instead of our line. This took a few weeks to get resolved and supposedly they took it out of their inventory. 2) Then, several months later I started getting reports that Vonage customers were getting "line unavailable" messages when trying to call the number. All of a sudden they had it back in their inventory again. And I need to call again to get them to get it out of their system. Half the techs I talked to there had no idea what to do, the other half escalated it to the group that could handle removing it from inventory. So if you port, be sure to have someone test calls originating from Vonage to be sure they didn't screw it up like I experienced. Regards, Charles Uchu
