Drop-call support

Some GSM devices support drop-calls. This comes in handy for basic control, e.g. for switch a GSM relay on/off or open/close entrance gate, because drop-calling is free of charge.

How to make a drop-call:

1. In the list, tap the device button to open device-specific page.
2. Click on icon to make a call, your default telephone app will pop-up
3. Make a call

Note: Some GSM devices drop the call automatically, for some the call has to be dropped by user.
