Using dual-tone multifrequency sig-
nalling
Your handset operates on the basis of digital informa-
tion transmission. However, certain applications,
for example, answering machines, can only be operated
using analog technology. For this you must send signals
using the dual-tone multifrequency signalling (DTMF)
process.
Depending on how your system is configured (auto-
matic tone dialling on or off - to be configured by the
service engineer) you must first switch to DTMF dial-
ling. This means, for example, that you can communi-
cate with a variety of voice storage systems.
You will find further details in the operating instructions
for the relevant applications.
