Changing Settings to Support PBX or Centrex
Services
You may need to change some or all of the following features if you want your

PBX or Centrex system and local calls outside the PBX or Centrex system).
However, if users in your PBX or Centrex system use a dial-out code (9 on most
PBX or Centrex systems) before dialing numbers outside the PBX or Centrex
system, the PARTNER system cannot prevent toll calls for extensions restricted
to "inside and local calls only" (unless you use Disallowed Phone Number Lists
(#404) to prevent dialing to specific classes of numbers). The Star Code Dial (toll
fraud prevention) functionality may not behave properly behind a PBX due to

restrictions on a line and also program PARTNER system restrictions, both the
