Using dual-tone multifrequency signalling
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 signalling (DTMF) process.
Depending on how your system is configured (automatic tone dialling on or off -
to be configured by the service engineer) you must first switch to DTMF dialling.
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.
