Conditions

WARNING

When you enable the Trunk-to-Trunk Call feature of DISA, and a third party discovers the personal identification number (PIN) (verified code PIN/extension PIN) of the PBX, there will be a risk that they will make fraudulent phone calls using the telephone line, and the cost will be charged to your own account. In order to avoid this problem, we strongly recommend the following points:

a)Carefully maintain the secrecy of the PIN.

b)Specify a complicated PIN as long and random as you can make it.

c)Change the PIN frequently.

•Hardware Requirement:

KX-TDA100/KX-TDA200: The OPB card and MSG card

KX-TDA15/KX-TDA30: The MSG card

•DISA Delayed Answer Time

It is possible to set the Delayed Answer time ( DISA Delayed Answer Time [209]) so that the caller will hear a ringback tone within a preprogrammed time period first before hearing an outgoing message (OGM).

•DISA Mute Time

It is possible to set the Mute time until the outgoing message (OGM) plays and the PBX starts to receive the DTMF signalling after the caller reaches the DISA line.

•Trunk-to-Trunk Call Duration

If a call between two outside parties is established, the call duration can be restricted by a system timer. ( 1.10.8 Trunk Call Limitation) If the timer expires, the line will be disconnected unless the originating caller retries by pressing "" or extends the time by sending any DTMF signalling. The caller can prolong the call duration within the preprogrammed time period ( DISA Trunk-to-Trunk Call Prolong Time [210]) and preprogramming number of times.

•Tone Detection

The following three types of tone detection can be enabled for each trunk group to disconnect a trunk-to-trunk call via DISA.

–Silence Detection ( DISA Silence Detection [475])

–Continuous Signal Detection ( DISA Continuous Signal Detection [476])

–Cyclic Signal Detection ( DISA Cyclic Signal Detection [477])

•Call Retry

While hearing a ringback, reorder, or busy tone, retrying the call is possible by pressing "". During a trunk-to-trunk conversation, the result of pressing "" is programmable: retry mode or DTMF mode.

•DISA Reorder Tone Duration

It is possible to set the DISA Reorder Tone Duration time. Reorder tone will be sent to the caller for a preprogrammed time period. When the timer expires the call will be disconnected. Retrying the call is possible by pressing "" during the DISA Reorder Tone Duration time.

•Call Deny

Extensions can deny DISA calls on a COS basis.

•Verified Code PIN Lock/Extension PIN Lock

If the wrong PIN is entered incorrectly three times, the line will be disconnected. If the incorrect PIN is entered a preprogrammed number of times successively, the PIN against
