Customer support Information
To minimize the risk of unauthorized access to your communications system:
Use a nonpublished Remote Access number.
Assign authorization codes randomly to users on a need-to-have basis,
keeping a log of ALL authorized users and assigning one code to one person.
Use random sequence authorization codes, which are less likely to be easily
broken.
Deactivate all unassigned codes promptly.
Ensure that Remote Access users are aware of their responsibility to keep the
telephone number and any authorization codes secure.
When possible, restrict the off-network capability of off-premises callers, via
use of Call Restrictions and Disallowed List capabilities.
When possible, block out-of-hours calling.
Frequently monitor system call detail reports for quicker detection of any
unauthorized or abnormal calling patterns.
Limit Remote Call Forward to persons on a need-to-have basis.
