Customer Support Information
Other Security Hints
Keep the system console and supporting documentation in an office that
is secured with a changeable combination lock. Provide the combination
only to those individuals having a real need to enter the office.
Keep telephone wiring closets and equipment rooms locked.
Keep telephone logs and printed reports in locations that only authorized
personnel can enter.
Design distributed reports so they do not reveal password or trunk
access code information.
Keep the voice messaging system Remote Maintenance Device turned
off.
Limiting Outcalling
When Outcalling is used to contact subscribers who are off-site, use the MERLIN
LEGEND Communications System Allowed Lists and Disallowed Lists or Automatic
Route Selection features to minimize toll fraud.
If the Outcalling feature will not be used, outward restrict all voice messaging
system ports. If Outcalling will be used, ports not used for Outcalling should be
Outward Restricted (for Merlin Mail Voice Messaging Systems, port 2 on a two-port
system, port 4 on a four-port system, ports 5 and 6 on a six-port system). Use
Outward Restriction, Toll Restrictions, Allowed Lists, Disallowed Lists and Facility
Restrictions Levels, as appropriate to minimize the possibility of toll fraud.
