Push-to-Talk (PTT) is a technology that has been used by two-way radios for decades. Modern-day PTT apps that use the same PTT technology are in trend, but PTT devices like walkie-talkie radios are turning obsolete. PTT solutions make use of cellular networks like 3G, 4G or WiFi networks to offer high audio quality and global coverage. Picking a PTT solution that offers an extensive feature set that aligns poorly with your business requirements is a formula for operational failure.
