AT&T announced that its Enhanced Push-to-Talk (EPTT) is now available to AT&T business customers through a new app available for iPhone 5 and iPhone 4S. AT&T says this is the first time a U.S. carrier is offering push-to-talk capabilities on iPhone.

In addition, EPTT can now be used over Wi-Fi giving U.S.-based customers improved in-building coverage and access to the service via compatible Wi-Fi networks. AT&T says it operates the U.S.’s largest Wi-Fi network with more than 32,000 AT&T Wi-Fi Hot Spots.

IDC analyst John Weber recently wrote that “the performance of AT&T’s EPTT service was comparable to traditional mobile voice services,” and that, “With many mobile workers working within the four walls of the enterprise, building in Wi-Fi functionality is an important element to consider.”

AT&T says the key features of its 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
