Page 8-6 Difficulty Making Outside Calls

What to do: Use system programming to check the extension’s calling
restrictions, if any (see Chapter 3 in
System Programming). If the extension is toll-
or outward-restricted, change it to unrestricted, if appropriate. Try again to make
an outside call from the extension.
■ If outside calls can now be made from the extension, you have solved the
problem.
■ If there is still difficulty making outside calls, go to Possible Cause 2.
Possible Cause 2: If the system (Hybrid/PBX mode) uses pool dial-out codes,
the extension may be restricted from dialing the pool dial-out code.
What to do: Use system programming to find out whether the pool dial-out code
has been assigned for the extension (see Chapter 3 in
System Programming).
■ If the pool dial-out code is missing, assign it if appropriate and try again to
make an outside call. If you can, you have solved the problem. If you
Cannot, go to Possible Cause 3.
■ If the pool dial-out code is not missing, go to Possible Cause 3.
Possible Cause 3: If the system (Hybrid/PBX mode) is set up for Automatic
Route Selection (ARS), the extension’s Facility Restriction Level (FRL) may be
set too low (see Chapter 4 in System Programming). The extension’s FRL must
be greater than or equal to the route’s FRL.
What to do: Use system programming to check the extension’s FRL.
■ If the FRL is set to less than 6, increase the FRL to 6 and try again to make
an outside call. If the telephone can now make outside calls, adjust the
FRL as needed. You have solved the problem.
SECURITY l ALERT:
!
Changing the extension’s Facility Restriction Level may compromise the
security of your system. If you leave the FRL at 6, ensure that the person at
the extension is authorized to make toll calls. For more information, consult
the section entitled “Automatic Route Selection” in the Feature Reference
and “Security of Your System: Preventing Toll Fraud,” in Appendix A,
“Customer Support Information.”
■ If, after setting the FRL to 6, the problem still exists, change the FRL back
to the original setting and go to Possible Cause 4.
Possible Cause 4: A Disallowed List is assigned to the extension.
