Call Restriction
Call restriction is an advanced feature that allows you to restrict your phone
from making certain types of calls. Trying to make a restricted call will
result in a rejection tone, followed by a dial tone.
On the NIU, you may choose a predefined call restriction level, or you may
customize the call restriction level. Nine different levels are available.
Call restriction levels
Call restriction levels 0–6 are subject to change and are currently defined as
follows for the U.S. market:
0 - All calls allowed (default setting)
1 - No 1(900)XXX-XXXX or 976-XXXX calls
2 - Level 1 plus no international long distance calls (011-XXX...)
3 - Level 2 plus no domestic long distance calls (1(XXX)XXX-XXXX
and 0(XXX)XXX-XXXX)
4 - Level 3 plus no special services (X11, except 911)
5 - Level 4 plus no special features (*XX...)
6 - No calls except emergency calls (911)
Call restriction levels 7, 8, and 9 can be customized to serve your needs.
These enable you to add or remove different types of restrictions, one at a
time.
