Service observing
 — Allows the user to monitor the conversations of those stations listed 
in the 
service observing list
 for his/her station. If this is enabled, you must enter a list of al-
lowed extensions. 
Note:
  A Department number can be entered as an extension in the Service Observing list and 
will then automatically include all members of the Department even if the members of 
the Department are later changed.

Toll restriction
 — “YES” allows the user to place toll calls. If “NO,” the user can only make non-
toll calls or calls to numbers listed in the allow exception table. 
9. 
System speed dial 
 — “YES” allows the user to access and place system speed dial calls. 
Example:
Here is a portion of a completed Programming Worksheet (Appendix II) 
for extension feature authorization. Note that: 
•  Extension 100 cannot record calls but 
can
 make toll calls (except those listed 
in the deny table) and can access the system speed dial numbers. 
•  In comparison, Extension 102 cannot make general toll calls but also can call 
any system speed dial number, 
even if it’s a toll call
. 
•  (Extension 110 doesn’t have DND, record or service observing  
capability because it’s an analog port.)
