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’s 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.
