UMD uses a product by RedSky called MyE911 in order to properly route emergency calls to the nearest PSAP (Public Safety Answering Point) operators while remotely using Cisco Jabber softphone.
This application is required for anyone using a Cisco softphone with UMD’s phone system for federal E911 compliance. If MyE911 is not installed, you will lose access to softphone features. Softphone access must be provisioned before attempting to install this application. Submit a Softphone request form to get access. After initial setup, MyE911 will run silently in the background, and request or verify your location whenever a network change is detected.
If you want more information, the official MyE911 User Guide PDF is available here.
