I just finished up porting from Voice Wing. I expect VZ will, in my case it did, disable your logon ability as soon as number is ported. It took 10 days to complete the port after I sent my required documents. Sending these documents is not made clear when signing up for the service initially. I happened to stumble across the requirement while reading the FAQs and then called support to verify.

With the exception of a few network adminstration adjustments, my service is up and running. I got one of the LinkSys PAP2T and it PnP behind a LinkSys router. So far, so good. There is so much more versatility managing your calls with Voipo. I think you'll like it over what VW offered.

You can call/email support and get an estimated date on the port.
