External Calls
Calling an Outside Number
To call outside your CBX system, you must first dial
your trunk (outside line) access code before dialing
the number you want to reach.
If all trunks are busy when you make your call, you
will hear a fast busy tone. If your system has queuing,
you will receive the queuing tone and can then use
Trunk Callback Queuing or Trunk Standby Queuing
to wait for the next available trunk. See “Trunk Call-
back Queuing” on page 3–40 and “Trunk Standby
Queuing” on page 3–41.
In this guide, 9 is used as the access code for a trunk.
Your CBX system administrator can tell you your
trunk access code.

Your system may also prompt you to enter a personal
identification number (PIN) to make an external call.
See “Personal Identification Number (PIN)” on page
1–14 and “Forced Authorization” on page 7–18.
