Microphone Mute

Talk to a co-worker in your office without your caller hearing the conversation.
User Operation
Microphone Mute


Microphone Mute lets a keyset user turn off their phone’s handset or Handsfree microphone at any time. While the extension is on-hook, Microphone Mute mutes the Handsfree microphone. While off-hook, Microphone Mute mutes the handset microphone. Once activated, Microphone Mute prevents the caller from hearing conversations in the user’s work area. The user can turn off the Handsfree or handset microphone while their telephone is idle, busy on a call, in DND or while an outside call is ringing. Answering a call automatically cancels Microphone Mute.

While an extension has their microphone muted, an incoming voice-announced Intercom call announces with a single beep (splash tone).
