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.

Maximum number of simultaneous OGM channels
If no DSP card is installed, the maximum number of simultaneous OGM channels is 2. If a DSP card is
installed, the maximum number of simultaneous OGM channels is 64. However, in this case DSP resources
will be used.
•
DSP Resource Usage
A DISA call requires a certain number of DSP resources. If all DSP resources are in use, this operation
cannot be performed. To ensure a minimum level of performance, DSP resources can be reserved for
conference calls. (

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