Push-to-Talk (a.k.a PTT or Press-to-Talk/Transmit) is a method of communicating that involves pushing a button and speaking into a receiver in order to transmit a message. Think Walkie-Talkies or CB radios. The overall goal of Push-to-Talk communication is to separate voice transmission and reception.
