list-menuFeedback?
This Help article is for Cisco Wireless Phone 9821 registered to Cisco Unified Communications Manager (Unified CM).

You can configure the E911 location service on Cisco Wireless Phone 9821 to have an active location URI for emergency calls. The location of the phone can contain the street address, building number, floor number, room number, and other office location information. When you dial an emergency number, the emergency responder receives the phone location and a call-back number. If an emergency call disconnects, the emergency service uses the call-back number to reconnect to the caller.
