DTMF
If the numeric keys on the telephone are pressed during an existing connection, so-called Dual Tone Multifrequencies (DTMF) are generated. This allows specific information to be transmitted to the PBX, provider or destination. To automate this, you can assign a function key with a phone number to be dialled and a DTMF sequence to be transmitted afterwards.
For correct execution, the method of DTMF transmission must be set separately for identities.
