• "Default filters for the North America profile" on page 436

Default filters for the North America profile
Filter 00 permits unrestricted dialing and cannot be changed.
Filter 01 is pre-programmed with 10 restrictions and some associated overrides. In Filter 01,
Restriction 02 and Override 001 allow long distance toll free calls.
The dialing string 911, which is the number for emergency assistance in North America, is
included as both a restriction and an override in Filter 01. This arrangement prevents anyone from
blocking calls for emergency assistance on lines or sets using the default filter.
