Number portability: myths vs. reality
Tom Keating has a great post on the nightmare reality vs. the myth of number portability. For the full details, read his post, it’s a gem. In a nutshell:
Summary of Porting:
- Carrier/cable to VoIP – Good
- VoIP to VoIP – Good (if the number was originally owned by a phone company & ported. If the number was owned by the VoIP service provider when you signed up, most likely you will not be able to port.)
- VoIP to Carrier/cable – Bad
In short, Tom concludes:
It would appear that you can port from a phone carrier to a VoIP provider, AND you can port from one VoIP provider to another VoIP provider, BUT you cannot port your number BACK to a traditional phone carrier or a cable company.
