/mcpInteraction Feature PSAP CallBack rings only on the device which made the emergency call even if the line is shared by different devices. Phone A and Phone B share a Directory Number (DN). If the emergency number is dialed using the translation pattern, an ELIN is associated for this outbound emergency call. If the call is disconnected, and the ELIN is called back using PSAP CallBack, the call is routed to Phone A only, the device from which the call originated. Shared Lines Emergency Call Handler Troubleshooting About Emergency Call Handler Troubleshooting Scenarios This section provides information about some Emergency Call Handler troubleshooting scenarios in the following areas: • Configuration Scenarios • Outgoing Calls Scenarios • Incoming Calls Scenarios Configuration Scenarios Emergency Calls Get Busy Signals and Are Not Routed Problem: Emergency calls get busy signals and are not routed. Solution: If a user who is dialing the emergency call is running a reorder tone, perform the following checks: • Check whether the translation or route pattern for the emergency call has been used. This may require checking for the device or phone on CSS. • Check whether the Is an Emergency Services Number check box has been checked for the translation or route pattern of the emergency call, and that it is correctly routing to the gateway. If the user who is dialing the emergency call is not reaching the correct gateway or Public Service Answering Point (PSAP), check that the settings or device pool settings for the phone or device are configured with the correct Emergency Location (ELIN) Group.
