During a secure call the following information is displayed by PrivateGSM:
- key exchange status at the beginning of the call;
- connection quality.
To establish a call PrivateGSM completes three phases shown by three icons:
Call status icons
Starting the connection
Connection not yet established. This step may take several seconds
Connection established but encryption keys are being exchanged.
Secure call established
Connection established and secure. You can now speak securely
Call quality level
Some factors of the mobile network (i.e.: GPRS use, poor signal, frequent radio cell changes, roaming) could decrease the audio quality of the call, increasing voice delay. Three variants of the call status icon shows the current call quality level.
Call quality level icons
Poor connection quality
Average connection quality
Good connection quality
If the connection quality remains poor we suggest you to seek for better network coverage or connect to broadband Wi-Fi access point.
