View source for PTT mode - IP Speakers

{{AI}}
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]]:
# Go to '''Users & Stations'''
# Select the IP Speaker from the list box
# Press the button '''Events'''
