A best-in-class user experience.

QChat enables simultaneous access to 3G or 4G PTT, data, and voice on the same device, which allows users to receive alerts, PTT calls, voice calls, and text messages even while on another PTT call or voice call, or while navigating the web. In addition, QChat is the only solution that provides guaranteed talk permit, ensuring that when a user hears the PTT “chirp,” their voice can be transmitted and heard by the recipient.
