Using dual-tone multifrequency sig-nalling
Your handset operates on the basis of digital informa-
tion transmission. However, certain applications, e.g.
answering machines, can only be controlled using ana-
log technology. For this you must send signals using the
dual-tone multifrequency signalling (DTMF) process.
Depending on how your system is configured (automat-
ic 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 storage systems.
You will find further details in the operating instructions
for the relevant applications.
