Dynamic Emergency Calling

Emergency calling that determines a user's current location from the network so emergency services receive accurate location.

Definition

In Teams, clients identify their network location by subnet, Wi-Fi access point BSSID, switch chassis ID or port (via LLDP), and the Location Information Service maps these to civic addresses. Emergency calling and call routing policies notify security desks and route calls appropriately. Webex Calling and Cisco Emergency Responder offer comparable capabilities for Cisco environments.

Example

A remote worker's laptop on the Building 2 Wi-Fi BSSID passes Building 2's address to the PSAP.

Exam tip

Know that network identifiers (subnet, BSSID, switch, port) map to emergency locations in the LIS.
