Conditions
WARNING
There is a risk that fraudulent telephone calls will be made using the Outside-to-Outside (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 (Trunk Security or All Security).
b)
Maintaining the secrecy of passwords.
c)
Selecting passwords that are complex and random, so that they cannot be easily guessed.
d)
Changing passwords regularly.
• The maximum recording time of each message is 3 minutes.
• The preinstalled DISA/UCD OGM card can play only one message at a time and the total recording
time of the PBX for DISA/UCD OGMs is 3 minutes.
• To use this feature, "DISA" must be selected as the distribution method for the desired outside (CO) line
port ( CO Line Mode—Day/Night/Lunch [414-416]).
• DISA Delayed Answer Time
It is possible to set the DISA Delayed Answer time (
caller will hear a ringback tone for a preprogrammed length of time before hearing a DISA OGM or a
short beep.
• Call Forwarding (FWD) to Outside (CO) Line
When a DISA call is forwarded to an outside party, the caller is not required to enter a DISA security
code regardless of the security mode.
• DISA OGM 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 (
connected. After the DISA OGM Mute Time passes, DTMF signals are recognised by the PBX and the
DISA OGM begins playing or a short beep is sent.
• SMDR
The following are logged by SMDR for DISA calls (
(SMDR)):
– The destination of the DISA call
– DISA security code status
• Call Deny
System programming determines which extensions can receive DISA calls (
Assignment [516]). If a DISA call is received at an extension that has Call Deny set, the caller will hear
a reorder tone and the call will be disconnected automatically. If a DISA call is received by a DISA ring
group, this programme does not function for extensions in that DISA ring group and these extensions
will still ring.
• Cyclic Tone Detection
It is possible to select the number of times a cyclic tone must be detected while the DISA OGM is sent
( Cyclic Tone Detection [513]). Cyclic Tone Detection can be used to disconnect an outside-to-
outside (CO-to-CO) line call via DISA.
• Fax Connection
System programming determines the extensions that are able to receive fax data when the PBX
receives a fax (CNG) tone via the DISA feature (
extension will automatically have the Data Line Security feature set.
• Fax Tone Detection
It is possible to select the number of times the fax (CNG) tone must be detected while the DISA OGM
