Enhanced 911 (E.911)

This E.911 feature allows you to configure one of three sources the phone obtains location information from:

  • DHCP via option 99
  • LIS compliant with RFC 5985

Configuring the source of location information allows the phone to share its location details in the invite sent when a 911 call is made to ensure the 911 operator dispatches emergency services to the correct address.
