Restrict Code Tips
1. Do not use restrict codes without first requiring a password for access.
Password protection is far more effective in preventing abuse than restrict
codes.
2. Test your system to determine whether dial tone is returned when a called
party hangs up, as follows. Connect a telephone to the line intended for use as
a the M-106E outgoing line. Test for dial tone under several conditions. Dial a
local extension, voice mail, and a local Central Office exchange number ( a
telephone number with the same prefix as yours) and wait for the called party
to hang up. Dial several incomplete and nonexistent numbers and wait for the
recorded announcements or intercept operators. If dial tone is returned in any
of these cases, the M-106E will not be able to restrict calls. Unauthorized
numbers (1+, 0+, 9+ and so on) may be restricted by the Central Office or the
PBX, however.
3. Use outgoing line toll restrictions supplied by the Central Office or the PBX
whenever possible, whether or not the M-106E restrict codes can also be used.
