Enhanced PTT is currently supported on iPhone 5, 5s, 5c, 6, 6 Plus, 6S and 6S Plus, and requires AT&T wireless service plus monthly Enhanced PTT subscription.
AT&T Enhanced PTT is the premier enterprise-grade carrier push-to-talk solution for large or small organizations, with superior performance, features and reliability. Enhanced PTT uses next-generation Voice over IP technology to deliver one-to-one or group calls over the AT&T 3G or 4G networks or on compatible WiFi networks.
Key features of Enhanced PTT include:
* 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
Enhanced PTT is available for AT&T Wireless customers only and cannot be used with international roaming. Continued use of GPS running in the background can dramatically decrease battery life.
