Can a different address somehow be bound to one of the devices, even if there is only 1 phone number shared amongst all of them?  If the E911 service cannot identify devices in their database on some basis other than by telephone number (MAC address, maybe? transmitted in a custom SIP field?), I don't see how that is possible given the nature of today's systems, as Mr. Blenke explained.

legacy TDM PBX with old-school OPX leased lines?  What, if any, are the
9-1-1 requirements there?
