Push-to-talk (PTT) is a new approach to voice communication which emulates walkie-talkie system. The main purpose of this project is to implement PTT on a cellular mobile phone (PoC). PoC is an instant messaging service like a voice sms. instead of dialing, you "push" a button and speak. When you release the button the message is sent. Communication is bidirectional but not simultaneous (half-duplex).
