AT&T Brings PTT to iPhone for Its Business Customers
AT&T today announced a new application that delivers push-to-talk walkie-talkie functionality to the Apple iPhone 5 and iPhone 4S. According to AT&T, the application supports large contact lists and talk groups, allows businesses to combine PTT services with enterprise mobile applications, and provides businesses with supervisory override so they can communicate with all PTT-enabled devices at the same time. AT&T claims that calls can be setup in less than one second. In addition to the new iPhone app, AT&T announced that its Enhanced Push-to-Talk service can now be used over Wi-Fi networks as well as its cellular network. This is the first time that PTT has been available on the iPhone from a U.S. carrier.
