Call connection phases
To establish a call PrivateGSM completes three phases indicated by three icons:
 Image Removed | 1. Red light: the connection is starting. This step may take several seconds. |
|---|
 Image Removed | 3. Green light: secure call is established. You can now speak securely. |
| Info |
|---|
The Yellow light is not listed because the key exchange phase is so fast that it can't be displayed. |
