AT&T announced today that its Enhanced Push-to-Talk is now available to business customers through a new app for iPhone 5 and iPhone 4S. AT&T is the first U.S. carrier to offer this push-to-talk, or walkie-talkie style of communication, on the iPhone.

With Enhanced Push-to-Talk capability, iPhone business customers won’t have to dial a number to call someone, and instead can push a button on the iPhone to broadcast a voice message to a group of people. The feature can be used over Wi-Fi, which gives U.S. customers more in-building coverage and access to the service through compatible networks and the company said it operates using the U.S.’s largest Wi-Fi network, which includes more than 32,000 AT&T Wi-Fi Hot Spots.

AT&T promises that its push-to-talk service supports up to 250 people, but it’s only available to business customers using the iPhone right now.

Key features of AT&T’s Enhanced Push-to-Talk for iPhone include:

  • Larger contact lists and talk groups than competitive push-to-talk solutions
  • Ability to combine push-to-talk services and mobile applications, with help available from AT&T’s team of mobility consulting and integration experts
  • Supervisory override that allows supervisors to communicate important time sensitive messages to their team
  • Call setup in less than one second

If you’re an iPhone business customer on AT&T’s network, the AT&T Enhanced Push-To-Talk app is now available to download on the App Store for free.
