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.

!SECURITYlALERT:

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.

What to do: Use system programming to check whether a Disallowed List is assigned to the extension (see Chapter 3 in System Programming).

■If a Disallowed List is assigned to the extension, remove it if appropriate. Try again to make an outside call. If you can, you have solved the problem. If you cannot, go to Possible Cause 5.

■If a Disallowed List is not assigned to the extension, go to Possible Cause 5.
