Source note · Webex Calling Site Survivability Gateway
E911 calling in Survivability mode requires a PSTN circuit or SIP trunk, outbound emergency calls use a specific registered Emergency Location Identification Number for a defined Emergency Response Location, and if the emergency operator returns a disconnected call the Survivability Gateway directs it to the last device that called the emergency number.
