CAUTION
•
The software contained in the TRS/Barring and ARS features to allow user access to the network must be
upgraded to recognise newly established network area codes and exchange codes as they are placed into
service. Failure to upgrade the on-premise PBXs or peripheral equipment to recognise the new codes as
they are established will restrict the customer and users of the PBX from gaining access to the network
and to these codes.
KEEP THE SOFTWARE UP TO DATE WITH THE LATEST DATA.
•
There is a risk that fraudulent telephone calls will be made in the following cases:
–
A third party discovers a personal identification number (PIN) (verification code PIN or extension PIN)
of the PBX.
–
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.
Keeping PINs secret.
b.
Selecting complex, random PINs that cannot be easily guessed.
c.
Changing PINs regularly.
•
To the Administrator or Installer regarding account passwords
1.
Please provide all system passwords to the customer.
2.
To avoid unauthorised access and possible abuse of the PBX, keep the passwords secret, and inform
the customer of the importance of the passwords, and the possible dangers if they become known to
others.
3.
The PBX has no passwords set initially. For security, select an installer password as soon as the PBX
system is installed at the site.
4.
Change the passwords periodically.
5.
It is strongly recommended that passwords of 10 numbers or characters be used for maximum
protection against unauthorised access.
