Frequently Asked Questions About Push-To-Talk

What is Push-to-Talk?
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. Today’s Push-to-Talk technology operates in much the same way using modern phones and apps like Zello.
How does Push-to-Talk Work?
Push-to-Talk technology revolves around that old two-way form of communication. Those transmitting cannot hear communications and those receiving cannot speak. This helps to eliminate background noise and streamline communications. Previously, PTT communication was only available on radio frequencies, but now you can use Push-to-Talk over Cellular or Wireless connections on private channels.
Why use a Push-to-Talk App?
Because of its simplicity, Push-to-Talk is the easiest method of communication for teams encountering many different kinds of situations, from drivers out on delivery routes to hospitality workers communicating across a big hotel to ambulance drivers headed to the scene of an accident. PTT apps like Zello are more advanced and modern forms of the more traditional Push-to-Talk devices or Push to Talk phones. Zello can be used directly on a regular smartphone, eliminating the need to carry around bulky additional equipment. Once downloaded, the Zello Push-to-Talk service transforms your regular phone into a PTT walkie-talkie-like device, complete with its own “Push-to-Talk” button. Other benefits of the Zello app include a comprehensive location tracking.
