Push-to-talk over cellular

Our instant voice solution, also known as push-to-talk over cellular or PTToC or PTT is a secure two-way VoIP (Voice over IP) radio service for businesses. It enables users to communicate one-on-one and in groups with a single push of a button, anywhere in the world. Users can also share written messages, images, videos and files.

Unlike traditional two-way radio systems, PTToC uses national cellular networks and provides the stability of mobile phones.
