PTT mode - IP Speakers

From Zenitel Wiki


To prevent acoustic echo during two-way communication with an IP speaker with microphone, the speaker must operate in "PTT-mode" (Simplex mode).

PTT-mode means that the operator needs to press the M-key or *-key to talk, and release the M-key (or press the #-key) to listen. This article describes how to configure "PTT-mode" when the IP Speaker is used in an ICX-AlphaCom or AlphaCom XE system.

We assume that the IP Speaker is already configured and registered to the ICX-AlphaCom server.

Start the configuration tool AlphaPro:

  1. Go to Users & Stations
  2. Select the IP Speaker from the list box
  3. Press the button Events
