Cisco Unified Communications Manager (Unified CM) can serve users on the customer premises and also users not on the customer premises (off-premises), using remote Virtual Private Network (VPN) connections. When users are on-premises, their location can be discovered automatically, by Unified CM Device Mobility or by Cisco Emergency Responder (ER), for the purpose of determining how to route emergency calls to the appropriate Public Safety Answering Point (PSAP) and to indicate the caller’s location to the PSAP. Without correct location information, emergency calls may reach a PSAP that is unable to dispatch emergency services to the caller’s location, or emergency services may be dispatched to the wrong location.
The Remote Worker Emergency Calling feature supported by Unified CM and ER enables customers to extend reliable emergency calling support to remote workers, by requiring remote workers to confirm or update their location whenever their device registration is interrupted. Users of devices designated for off-premises (connected remotely to the customer network) use are first presented with a (customizable) disclaimer notice, which assures that users are aware of the need to provide correct location information. Then the off-premises location currently associated with the designated device is presented. Users may confirm their current location or select another previously stored location from their device display; if their location is new, then they are directed to the ER Off-Premises User web page to create a new location.
Prior to completion of this process, the user’s device may be restricted by the customer to calling a single configured destination. This assures that the user has acknowledged the disclaimer and provided their current location information before the user’s device is enabled for normal use.
Intrado V9-1-1 service validates and stores the location the user provides, and emergency calls from off-premises users are forwarded by ER and Unified CM to Intrado. Intrado routes emergency calls to the PSAP with jurisdiction for the caller’s location and delivers the user-provided location information together with each call.
