Using the lf>ice Module
Dialling through to an extension
(external callers)
Lines must be programmed for the DISA
feature by your BT engineer.
There is a feature called Direct Inward
System Access (DISA ) which allows callers
to ring directly through to an extension
provided that they know the extension
number of the person they wish to contact.
When the caller phones in on a line
programmed for D ISA the call will be
answered by the system. When the system is
in day service, the caller will hear the
following pre-recorded greeting:
'Thank you
for calling. If you know the extension number
you wish to contact, please dial the number. If
you require assistance, please wait or dial zero'.
This feature may be used without a Voice
Module but the caller will hear a tone instead of
an announcement.
The caller then dials the extension number
required.
(The caller's phone must be in tone
mode.)
The system will wait ten seconds for
the caller to dial the first digit, and a further
four seconds for the second digit. If the digits
are not received within that time, the call will
ring in as a normal incoming call.
When the caller enters the extension number
correctly, the extension will ring. If it is not
answered within
30
seconds, the call will be
presented as an incoming call. If the
extension is busy or an incorrect extension
number is dialled, the call will be presented
as an incoming call.
