Walking COS Through DISA
If the caller performs Walking COS (extension number and PIN entry) while hearing a DISA message, the
security mode can be temporarily changed to No Security mode (→ 2.7.5 Walking COS). After performing
Walking COS, the following features are available, using the settings of the specified extension:
•
Intercom call
•
TIE line call
•
Trunk call
•
Call Forwarding (FWD)/Do Not Disturb (DND) setting (→ 2.3 Call Forwarding (FWD)/Do Not Disturb
(DND) Features)
•
Incoming Call Distribution Group Log-in/Log-out (→ 2.2.2.7 Log-in/Log-out)
•
Absent Message setting (→ 2.20.2 Absent Message)
•
Extension Dial Lock (→ 2.7.3 Extension Dial Lock)
•
Time Service Switching Mode (→ 5.1.4 Time Service)
Note
When making a trunk call using Walking COS through DISA, the CLIP number for that call will be that of
the extension seized by Walking COS. (→ 4.1.2.2 Calling/Connected Line Identification Presentation
(CLIP/COLP))
DISA Automatic Walking COS
Registered outside destinations such as cellular phones can be automatically recognised as PBX
extensions when calling through DISA. When the Caller ID of a received trunk call matches an entry in the
System Speed Dialling Table, the calling telephone is given Walking COS authorisation as assigned to the
corresponding CLI destination extension. Therefore, the "CLI destination" setting in the System Speed
Dialling Table is used here to specify the target extension that the calling telephone will be recognised as for
Walking COS.
