This is a way of communicating on the half-duplex communication line, includes receiving and transmitting devices (walkie-talkie) by the way of pressing the button for switching to the voice mode or transition to the listening mode. It works as a radio speaker; one can talk by pressing the button and can listen to a voice message by releasing the button.
TeleCable Services is primarily an Internet based company and while we do have customer service representatives on hand, emails are generally handled much faster than direct phone calls.
