6.5 Suffix Dialing (DTMF)
When communicating with and controlling a voice mail system, or when
retrieving information about your bank account through your phone, you
need to use Dual Tone Multi-Frequency (DTMF) signals, also known as
suffix dialing.
The suffix dialing function is always active for all calls in speech.
All digits entered are converted automatically by the exchange into
DTMF signals, which then are transmitted along the connected lines.
