WARNING
When 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.
•Manager Password
One manager password can be assigned per PBX (
