6.5 Suffix Dialing (Dialing During Speech)
When communicating with and controlling a voice mail system, or when
retrieving information about your bank account through your phone, you must
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 automatically converted by the exchange into DTMF
signals, which then are transmitted along the connected lines.
