AT&T 3 manual Security Alert

Putting the System Unit Back Together

Security Alert:

Outcalling introduces the risk of toll fraud abuse. Outgoing Call Restriction, Allowed Lists, and Disallowed Lists can reduce the risk. Extensions connected to the mail system ports should be restricted as much as the needs of the business allow.

For the extensions connected to port 1 on a two-port system, ports 1, 2, and 3 on a four-port system, or ports 1 through 4 on a six-port system, Outgoing Call Restriction should be set to Inside Only.

For the extensions connected to the Outcalling ports (port 2 on a two- port system, port 4 on a four-port system or ports 5 and 6 on a six-port system), Outgoing Call Restriction should be set to the most restrictive value that the business allows; then Allowed and Disallowed Lists should be assigned as needed. For example, if Outgoing Call Restriction is set to Inside Only, an Allowed List containing all numbers to which Outcalls are allowed must be assigned to the extensions connected to port 2, port 4, or ports 5 and 6.
