PTT APP

Push to Talk over Cellular is a Cloud based Communication Server Solution that enables instant and reliable voice communication over cellular networks. It allows users to push a button to speak and release it to listen, much like a two-way radio.
This Solution uses cellular data networks to transmit voice data, which eliminates the need for expensive radio infrastructure and provides broader coverage.
