# Mass Audio Notification

## Description

The Mass Audio Notification feature allows audio notifications to be sent to multiple telephone sets within a network zone. Audio notifications generated through a mass notification application (for example, Mitel Revolution) are played over the handsfree speaker of a set.

The MiVoice Business system connects the sets in a network zone with a mass notification application through the Mass Audio Notification form.

## Conditions and Feature Interactions

- If a set's handsfree speaker is in use, then the Mass Audio Notification stream is held back from being played over the handsfree speaker. For example, if a set receives a Mass Audio Notification while you are on a handsfree call, then the audio notification is not played over the handsfree speaker.

- If a set belongs to a network zone configured for Mass Audio Notification, then Off-hook Voice Announce (OHVA) does not function for that set.

- If a Hot Desk user is logged in to a Mass Audio Notification compatible MiNET set, then the set will receive audio notifications only for the Zone ID assigned to the registration telephone DN and not the Zone ID assigned to the Hot Desk user's DN.

- Mass Audio Notifications are not reported by the following features: Call History (system and device side), Station Message Detail Recording (SMDR), MiTAI, and Real Time Events (RTE) for Automatic Call Distribution (ACD).

- If a failover occurs when a Mass Audio Notification is playing over the handsfree speaker of some sets, then the audio notification stops playing and resumes (if still active) after the affected sets connect to the secondary MiVoice Business server. Similar behavior occurs during failback to the primary server.

- Maintenance logs are not recorded for the Mass Audio Notification feature.
