[Advanced e911 - granular based on room or building]

I'm answering an RFP with a request for advanced e911 location based on the port the phone is plugged into. I imagine this can be done crudely with a unique e911 number for each building, floor, room (depending on granularity) and then updating the devices using LLDP and the Kazoo API.

Has anyone tackled granular e911 locations for larger buildings?

I've noticed in Bandwidth newsletters that they are working on this, https://www.bandwidth.com/9-1-1/

We'd like to get started on some simple Monster-UI apps. Maybe a talk/training on creating an App start to finish with some advanced things such as storing app specific data in the database?
