[VoiceOps] Automatic 911 location updates

[Matthew Crocker]

Location information should be pushed to the phone via DHCP.  The DHCP server can get option82 information from the PoE switch port.  The phone should then include the information in an INVITE for emergency calls based on its dial plan. The carrier can pass the information through to the NG911 PSAP.
