[VoiceOps] Automatic 911 location updates

[Carlos Alvarez]

Now there's an idea that is both easy to implement, and should be
reliable.  Of course, for home routers then you'd have no 911 location
though.  But at least at a company level they'd auto-provision.  On the
other hand we can do that one by IP too.
