There's PS/ALI (Private Switch Automatic Location Information) that's
quickly becoming state mandated for all PBX systems.  The problem with it
is if your customers are spread out across multiple PSAPs or RBOCs.  Then
you've got to interface with the PSAP or RBOC in every area where you've
got a customer.  Then you've also got to assign a DID to every customer
that can be transmitted  back to the PSAP over the PRI or CAMA trunks
(which are necessary to use E-911).

Its fine if you're limited to one or two PSAPs in your service area, but a
company like Vonage or NuFone has an almost unlimited number of PSAPs in
their coverage area.
