Operation Modes

Mode	Command	Description

How does an incoming call work?

A call arrives at the device
The Caller ID is verified against the configured number list (CID00-CID09)
If the number is in the list:
- The CIDxx+ trigger is generated (where xx is the position 00-09)
- An automatic action can be executed via rules
- Optionally the call is answered to start audio session
If the number is NOT in the list: the call is ignored

The CIDxx+ trigger allows executing any action: activate outputs, send reports, start remote listening, etc.

Usage Examples

Remote control by call


// Configure authorized number in CID00
>SCID00 +5491112345678<
 
// When receiving call from that number, activate output
>SRL50E;TRG=CID00+;ACC={SSSXP0011}<

Remote listening on event


// Configure control center number in DS00
>SDS00 +5491198765432<
 
// When panic detected (IN01), call and activate listening
>SRL51E;TRG=IN01+;ACC={VCC001}<

Manual bidirectional call


// Start full duplex call to destination 00
>VCC002<    // 00 = destination, 2 = bidirectional mode
 
// Hang up call
>VCH<
