Prior Releases Features and Enhancements
Release 3.1 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 now 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 dialtone, 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 misrouting of the call. 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 is 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.
