[VoiceOps] Number Portability Within a Carrier

Well, the easy (?) way is to make a test call, or open a ticket with your tier 1.

But yes, I was stating directly that if your tier 1 doesn't provide you notification of line loss, they're incompetent.

In order to take your numbers away, the tier 1 would have to be involved (obviously) so if they don't notify you of a loss of customer, then that's just ridiculous. Generally, you can't tell otherwise, as the only difference between you and someone else is a route index in their switch, and a change to their billing system to account for usage. If you don't have access to one of those two items, you can't tell directly.
