Product Enhancements
Trunk-to-Trunk Transfer on a per-station basis
This enhancement to the trunk-to-trunk feature enables the system manager to
allow or disallow trunk-to-trunk transfer on a per-station basis. Beginning with
Release 3.1, the default setting for all stations is restricted.
Programmable Second Dial Tone Timer
Beginning with Release 3.1, the system manager can assign a second dial tone
timer to lines and trunks to help prevent toll fraud (for example, when star codes
are used). After receiving certain digits dialed by a user, the CO may provide a
second dial tone, prompting the user to enter more digits. If this second dial tone
is delayed, and the user dials digits before the CO provides the second dial tone,
there is a risk of toll fraud or the call being misrouted. The second dial tone timer
enables the system manager to make sure that the CO is ready to receive more
digits from the caller.
A Disallowed List containing numbers frequently associated with toll
fraud
Beginning with Release 3.1, Disallowed List #7 now contains default entries,
which are numbers frequently associated with toll fraud. By default, Disallowed
List #7 is automatically assigned to both generic and integrated VMI ports used by
voice messaging systems. The system manager must manually assign this list to
other ports.
Pool Dial-Out Code restriction for all extensions by default
Beginning with Release 3.1, the default setting for the Pool Dial-Out Code
restriction has changed to restricted. No extension or remote access user with a
barrier code has access to pools until the restriction is removed by the system
manager.
Outward restrictions for VMI ports by default
Beginning with Release 3.1, ports assigned for use by voice messaging systems
(generic or integrated VMI ports) are now assigned outward restrictions by
default. If a voice messaging system should be allowed to call out (for example, to
send calls to a user's home office), the system manager must remove these
restrictions.
!
SecurityAlert:
Before removing restrictions, it is strongly recommended that you read
Appendix A, ''Customer Support
New default Facility Restriction Level (FRL) for VMI ports
Beginning with Release 3.1, the default FRL for VMI ports has changed to 0,
restricting all outcalling.
