Telephoning
DTMF Post-dialling
DTMF post-dialling is only possible during external calls when, for example, an auto-
matic announcement prompts you to post-dial digits and symbols (1 to 0,
*
and #),
during fax polling, during a remote answerphone enquiry, or when communicating
with a voice mailbox or other application.
There is an external call. You hear e.g. the answerphone signal or an automatic
announcement.
You can now post-dial.
The external call remains connected.
Using this ISDN service, you can have the data of a malicious call recorded in your
telephone network provider’s exchange. The service must have been requested prior
to use and is charged for. For further details, please contact your network provider.
You receive a call from an undesirable caller.
Press the R-key, then the hash key, and dial 0.
Malicious Call Identification (MCID)
If you have a T-NetBox from Deutsche Telekom, saved messages or incoming faxes
are signalled by the "Message" LED (see the note on p. 53). Please refer to the T-Net-
Box User Guide for instructions on how to retrieve information.
In order to call the T-NetBox and retrieve your messages, you must always use a
telephone to which you have assigned the first MSN, because the LED signalling
is always transmitted to this number (cf. the section entitled "Call Assignment" on
p. 37).
Example: if you have configured your communications system so that calls to the
MSN with the code digit 1 are signalled on telephones 11 and 12, you can then use
both these telephones for T-NetBox enquiries.
