Persistent Microphone Mute

With this feature, you can enable the microphone mute to persist across all calls managed on a phone.

By default, users can mute the microphone during an active call, and the microphone is unmuted when the active call ends. With persistent microphone mute enabled, when a user mutes the microphone during an active call, the microphone remains muted for all following calls until the user unmutes the microphone or the phone restarts.

\When a user mutes the microphone when the phone is idle, the mute LED glows but no icon displays on the screen. When a user initiates a new active call with the microphone muted, the mute LED glows and a Mute icon displays on the phone screen.
