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.

Security Alert:
Before removing restrictions, it is strongly recommended that you
read “Appendix A: Customer Support Information.”
New default Facility Restriction Level (FRL) for VMI ports
Beginning with Release 3.1, the default FRL for VMI ports has changed to 0,
restriction all outcalling.
New default FRL for the Default Local Route Table
Beginning with Release 3.1, the default FRL has changed to 2 for the Default
Local Route Table. Now, system managers can easily change an extension
default of 3 to 2 or lower in order to restrict calling. No adjustment to the route
FRL is required.
New maintenance procedure for testing outgoing trunk problems
A password is now required for technicians to perform trunk tests.
