DISA
SERVICE
The DISA (Direct Inward System Access) system allows an external user to
call an extension directly.
The service will send the external caller a customizable message according to
the DAY, NIGHT and CUSTOMIZED profiles, prompting to dial.
Hi-Pro is provided with an immediate DISA service and a delayed DISA
service. With the immediate DISA service, upon an incoming call, no extension
will ring and the caller will receive the message immediately. With the delayed
DISA service, the extensions enabled to receive calls will ring, and the caller
will receive the message only if there is no answer after 10 rings.
Once heard the message, the external user can dial the number of the desired
extension.
If Hi-Pro does not detect any dialling within 5 seconds, or if the selected
extension is not enabled to receive DISA calls, the call will be diverted to
telephones enabled to receive calls from that line (if the selected extension is
enabled to receive DISA or “DDI from phonebook” calls: VIP calls, otherwise
the call is cleared).
In the event the selected extension does not answer within a programmed time
(factory setting 25 seconds), or it is engaged, and if it is enabled to receive DISA
or “DDI from phonebook” calls (VIP calls), the call is diverted to all the
extensions enabled to receive calls from that line, otherwise the call is cleared.
Note: To set DISA service please refer to paragraphs: “Service
Activation”, “DISA Programming” and “Automatic Operator
(IVR)” of the Installation and Programming manual.
Note: DISA Service messages are user customizable (please see
“Choosing
DISA
Message”
and
“Message
recording/playback/deleting”
of
the
Installation
and
Programming manual).
Note: The activation of DISA service does not inhibit the display of
the caller identification (CLI) for the incoming calls over the
line.
Note: Moreover, DISA service allows the access to the Control Menu
(Menu 10) for relays activation or for Handsfree ambient
listening (see “Accessing Control Menu” page 47).
Initial situation:
An external user is making a call from a multifrequency dialling telephone.
