The crowded or loose grains cause the electric current to become stronger or weaker. The current copies the pattern of the sound waves and travels over a telephone wire to the receiver of another telephone. For more modern phones that have a telephone answering service, the sound wave is captured on a recording device which allows for the operator of the phone to playback at a later time.
(Push-To-Talk) PTT is a two-way communication service that works like a walkie talkie. A normal cell phone call is full-duplex, meaning both parties can hear each other at the same time. PTT is half-duplex, meaning communication can only travel in one direction at any given moment; only one person can be heard at a time. To control which person can speak and be heard, PTT requires the person speaking to push a button while talking and then release it when they are done (hence the term Push To Talk.)
