Telephoning with the system while away
You can call up your TC system from anywhere and, for example, conduct ex-
pensive foreign calls using the system. The charges are then accrued by the
system. This is possible using any telephone with DTMF post-dialing.
“Telephoning via the system” must be released by service.
Service will also notify you of the tie line circuit discrimination code and of
whether a PIN code is necessary.
Call the number of your TC system from an external telephone, e.g.
0
6
9
7
5
05
.
Enter the tie line circuit discrimination code, e.g.
8
9
. You will hear a dialing
tone as confirmation.
If necessary, enter the PIN, e.g.
1
2
3
4
.
Enter the external line code of the system and the call number which you want
to call using the TC system, e.g.
0
0

. This number will be called
right away.
NOTE
In some cases you will only be able to telephone via the system from
certain, previously defined telephones. Service will notify you of this.
