Though Sprint is the carrier most often associated with push-to-talk because of its dying iDEN network, AT&T today announced that it will launch its own PTT service for Apple iPhone customers to let up to 250 people turn their phones into high-powered walkie-talkies. AT&T says it has expanded its push-to-talk options through a new Apple iOS app. The app allows customers to tap a button and instantly speak to a person or group of people that also use the service. This marks the first time that a carrier has support the function on an iPhone in the U.S.
AT&T already offers Enhanced PTT on select Android smartphones, and iOS availability extends the reach of its service to the Apple iPhone 5 and iPhone 4S. The feature works on 3G, 4G HSPA+, 4G LTE, or Wi-Fi using VoIP technology. The App Store description promises that the phone also supports:
- Fast call setup times and low latency
- Advanced push-to-talk features including real-time presence, Instant Personal Alerts, free/busy status and Supervisory Override
- Scalable to support large contact lists and talk groups
- Organizations can use a Corporate Admin Tool for easy management of users and groups
