If the application does not open or if at the time of the call you see the plane moving for a long time (staying in a "Connected" state), your firewall may be activated and prevent the application from working.
Check if you have security systems enabled on your internet connection, this happens mainly when you make a phone call while connected to the internet at work or in public places. (contact a responsible person in your company if you are not sure).
Also check if you have downloaded a virus-fighting application to your phone, these applications also block the operation of the application, set to allow Rogervoice to run.
If you're on Android and your phone has anti-virus software, here are the steps to reset the network :
After making these settings, you should be able to make correct calls with Rogervoice.
If you are still experiencing the same problem, contact us from the application. 😊
