If you look at the webpage of telecomsystems
(http://www.telecomsys.com) they state that their platform is GPS based.
I see no other way of doing this reliably than to put some kind of
GPS device into the VoIP unit.
While I agree that GPS is the likely answer, I wasn't expecting the
ability to work inside computer rooms and basements. Guess based on
the following article that it's possible. So, I guess we'll be seeing
Vonage replacing the Cisco ATA-186's with something that does GPS.
I suppose a downside is folks using the Vonage boxes outside the US
via VPN will be traceable by Vonage and could get shut down, if
Vonage wanted to enforce such.
Article regarding indoor GPS and other locator service.

If you can put a locator into a cellphone, I see no reason why you
cannot do the same in a VoIP unit.
VOIP units don't walk near windows or outdoors, but given the claims
made in the article, I guess it'll be possible.
Perhaps some nice inexpensive NTP sync hardware will come out of this
too. If the chips will work in the environments they list, perhaps
they'll also work in data centers, if all the tweaks discussed don't
affect clock sync accuracy too much.
