Conditions
WARNING
There is a risk that fraudulent telephone calls will be made using the CO-to-CO Line Call feature of
DISA.
The cost of such calls will be billed to the owner/renter of the PBX.
To protect the PBX from this kind of fraudulent use, we strongly recommend:
a)
Enabling DISA security (CO Line Security or All Security).
b)
Keeping passwords (verified code PINs/extension PINs) secret.
c)
Selecting complex, random PINs that cannot be easily guessed.
d)
Changing PINs regularly.
•
Hardware Requirement:
An MSG card.
•
DISA Delayed Answer Time
It is possible to set the DISA Delayed Answer time (
→
DISA Delayed Answer Time [209]) so that the
caller will hear a ringback tone for a preprogrammed length of time before hearing an OGM.
•
DISA Mute Time
Certain DTMF signals, such as Caller ID information, may be sent from the telephone company when
a call is first connected. Because these signals may interfere with DISA, the PBX can be programmed
to ignore DTMF signals for a specified amount of time (DISA Mute & OGM Start Time after Answering)
after a call is connected. After the DISA Mute time passes, DTMF signals are recognized by the PBX
and the OGM begins playing.
•
SMDR
The following are logged by Station Message Detail Recording (SMDR) (
→
Detail Recording (SMDR)) for DISA calls:
a)
The floating extension number of the DISA OGM.
b)
The destination of the DISA call. (Extension number for internal calls, telephone number for CO-
to-CO line calls.)
c)
The extension number used for Walking COS through DISA, or the verified code used for Verified
Code Entry through DISA.
•
Tone Detection
Three different types of tone detection can be used to disconnect a CO-to-CO line call via DISA. Each
tone detection type can be enabled or disabled for each CO line group.
–
Silence Detection (
→
–
Continuous Signal Detection (
→
DISA Continuous Signal Detection [476])
–
Cyclic Signal Detection (
→
DISA Cyclic Signal Detection [477])
•
DISA Reorder Tone Time
If a caller makes an invalid selection, a reorder tone will be sent to the caller. The caller can retry the
call by pressing " ", otherwise the call will be disconnected after a preprogrammed length of time
(DISA Reorder Tone time).
•
Call Deny
Each COS can be programmed to accept or deny incoming DISA calls. A DISA call will be accepted or
denied by an extension based on the COS of the extension.
•
When using Walking COS or Verified Code Entry, a PIN must be entered. If the PIN is entered
incorrectly three times when using DISA, the line will be disconnected. If an incorrect PIN is entered a
preprogrammed number of times, the PIN will be locked. Only an extension assigned as a manager can
unlock a PIN, after which it will be reset.
