Vocalis is the most complete Push-to-Talk system over cellular.

Vocalis is a Push-to-Talk (PTT) over cellular system that is easy to use, gives you complete control, and covers more of the nation because of our unique partnership with NextM2M. This means you get the best PoC (PTT over Cellular) solution for whatever your needs are at the best prices.


Restriction App

Our specially developed Vocalis Lock application can be installed along with the Vocalis app allowing you to block unauthorized usage by employees which can increase data costs. You choose the apps that are allowed to access cellular data.


Connect to WebGate

Only Vocalis connects your PoC devices to Datalink’s WebGate service. WebGate provides you with the tools to track everything in your fleet. WebGate merges different networks and a wide range of remote assets on a common screen allowing for easy asset monitoring.
