/mcpInteractions Interaction Feature Calls made by PSAP CallBack will overwrite a Do Not Disturb (DND) configuration of a destination device. If DND Call Reject is enabled, when the emergency number is dialed using the translation pattern, an ELIN will be 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 the phone irrespective of the phone's DND settings. Do Not Disturb Call Reject Calls made by PSAP CallBack will overwrite Call Forward All (CFA) settings of the destination device. If a phone has CFA enabled and if the emergency number using the translation pattern is dialed, an ELIN will be 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 the phone irrespective of the phone's CFA settings. Call Forward All PSAP CallBack will ignore the Single Number Reach (SNR) configuration. When a phone has SNR enabled with the Remote Destination pointing to a mobile number. If the emergency number is dialed using the translation pattern, an ELIN will be associated for this outbound emergency call. If the call is disconnected, and the ELIN number is called back using PSAP CallBack, the call is routed to the phone and not to the remote destination.
