Using DTMF dialing
Your handset operates on the basis of digital information transmission. However,
certain applications, for example answering machines, can only be operated us-
ing analogue technology. For this you have to send signals using the dual-tone
multifrequency signaling (DTMF) process.
Depending on how your system is configured (automatic tone dialing on or off -
to be configured by the service engineer) you must first switch to DTMF dialing.
This means, for example, that you can communicate with a variety of voice stor-
age systems.
You will find further details in the operating instructions for the relevant applica-
tions.
