11 Technical information
Switchboard external line
access code
When connected to an internal switchboard, you
may need to enter an access code (e.g. 9) to get
an outside line. So that the switchboard has time
to pick up an outside line, you may also need to
add a pause after the access code. A ‘pause’ lasts
3.6 seconds.
To insert a pause
1. Begin dialling a number and press where a
pause is required.
■ You may also need to insert a pause when dialling international
numbers, charge card numbers and with other tele-banking
facilities.
Recall
The button is used when connected to
certain switchboards, for example to transfer calls,
and for some BT Calling Features or those services
available via your network provider.
