There is also another service called WPS for cell phones where you get priority just by prefixing your number with *272, the only catch there is your specific phone needs to be enrolled.
Are you saying there's more than one 710 number? [Just Y/N]
In a nice bit of timing, HN Replies (my HN notifier) grabbed the comment before it was deleted! It was interesting, so I'm anonymously adding it below:

> I have seen first hand a large VoIP carrier reach out to an ITSP because one of their end subscribers was scanning the 710 number space either manually or not. And it was within a few minutes after the scan started. This type of activity (and others too) will set off all kinds of alarms at phone providers.
