DISA Security Mode
Security can be enabled for the PBX to control the types of calls that can be made by callers using DISA.
(→ DISA Security Mode [732]) However, note that the security setting does not effect DISA AA calls (AA
calls can only be made to preprogrammed destinations and security is not an issue) or Operator Calls (→
2.2.5 Operator Features).

Walking COS/Verified Code Entry through DISA
While the OGM is playing, DISA callers can use Walking COS (→ 1.8.4 Walking COS) and Verified Code
Entry (→ 1.8.5 Verified Code Entry) to:
a)
Make calls via DISA which are prohibited by the DISA Security Mode
b)
Gain access to certain features, such as FWD, Extension Dial Lock, etc. (Walking COS only)
This feature is particularly useful when a PBX user needs to make a business call while at home, or when
an extension user forgets to set FWD on his or her extension before leaving the office.
All privileges and restrictions on making calls that apply when the user is using an extension telephone are
also applied when using Walking COS or Verified Code Entry through DISA.
Additionally, setting features by using Walking COS through DISA can be enabled or disabled through
system programming for each Class of Service (COS). (→ 1.23.5 Remote Extension Control by User)
CO-to-CO Line Calls through DISA
DISA callers can use DISA to make CO line calls in either of the following situations:
a)
When the DISA Security Mode allows CO line calls
b)
When the caller uses Walking COS or Verified Code Entry through DISA, and his or her COS
allows CO line calls.
If a call between two outside parties is established via DISA, the length of the call can be limited to a
preprogrammed duration. (→ 1.10.8 CO Line Call Limitation) A timer will activate when the call is connected,
and a tone will be heard 15 seconds before the timer expires at five-second intervals.
At this point the call can be extended for a preprogrammed amount of time (→ DISA CO-to-CO Line Call
Prolong Time [210]) by pressing any dialing button excluding " ". 15 seconds before the extended time runs
out, the tone will be heard again.
The number of times a CO-to-CO line call can be extended is also programmable; if set to "0", calls can be
extended as many times as needed.
If the caller wishes to end the CO-to-CO line call but remain connected to the PBX in order to make other
calls or access other DISA features, the caller can press " " at any time to return to the original DISA OGM
(Call Retry).
