It is a challenge these days to get number portability sorted out. In fact in this case it was easier to go back to the PSTN than to use VoIP and try to port your number. See Tom's blog for details.
Number portability seems to still be a major problem in the world of VoIP and one of the first stories about the topic was by yours truly. In this article I mentioned I am switching from Vonage to AT&T CallVantage because I couldn't port my number.
Now it seems that AT&T CallVantage is the poor stepchild of AT&T -- who knows if this service will even last. There is little or no branding or messaging for this service. It will be interesting to see how CallVantage does in the next few years.

Interestingly enough, I recently switched from AT&T CallVantage (I did not have good experiences with them) to Vonage, and had no trouble porting my CallVantage-assigned number to Vonage. It took about 10 days, though. My frustration with CallVantage was this...every time I tried to pick up my messages online, I was assaulted with a barrage of junk, offers to download pop music, demands that I upgrade my software, ads, movie previews, etc. I told them about three times that I was considering switching...you'd think they would have addressed my concerns? Apparently they don't have a lot of interest in keeping customers. I am happier with Vonage.
