He's in the business of replacing existing phones and wire with new
equipment, and old key systems with PBX's and dial tone provided by a CLEC.

Suffice to say that experience has shown there are usually
interruptions to the dial tone during that kind of work, and in any
event he wants to have "his" number available for calls when in the
buildings out-of-hours. He's almost always able to find a data
connection, either by hooking up to an existing customer in the
building or by finding a wifi hot spot, using a Pringles antenna.

The benefit of having the VoIP line is that he can test a new PBX with
"live" dialtone when the company's numbers get fouled up during LNP
switching, and that happens a lot. He also likes to able to "transfer"
his calls to his house without having to go back to an office at the
end of the day (I don't know how Vonage does that, but he has two
Linksys boxes, one with him and one at home).

Anyway, the point is he makes it work somehow, and I'd like to be sure
that a 911 call via the Vonage box would show the correct address.
