Not easy; you're talking circuit IDs now, not portable numbers. You'd
have to have the telco come out and add new circuits, then remove the
old ones. That's going to be a lot of work in labor, and expensive as
hell.

What will follow from there will be reminiscent of the phreaker days.
Mostly, bad actors dialing into PBXs with unsecured outdials, and
making their calls from there.
