Using dual-tone multifrequency signaling

Your handset operates on the basis of digital information transmission. However,
certain applications, for example answering machines, can only be operated
using 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
storage systems.
You will find further details in the operating instructions for the relevant
applications.
