Conditions
CAUTION
There is a risk that fraudulent telephone calls will be made using the Trunk-to-Trunk 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.
Keeping passwords (verification code PINs/extension PINs) secret.
c.
Selecting complex, random PINs that cannot be easily guessed.
d.
Changing PINs regularly.

Hardware Requirement:

programming selects whether pressing " " during a trunk-to-trunk conversation returns to the DISA top
menu or sends a DTMF tone.

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.
