The CyberData Singlewire-enabled Push-to-Talk speaker enables two-way conversations using the Singlewire Push-to-Talk application running on the phone. The Push-to-Talk Speaker easily connects into local area networks with a single CAT5/6 cable from your PoE switch. Its small footprint allows the speaker to be mounted almost anywhere with multiple mounting options available. By use of the optional remote call button, calls to a predetermined extension can be initiated from the room with the speaker. During the active calls, the LED light on the switch can be programmed to blink to show call activity.
