Calls That Require a Billing Code or Authorization Code
Your administrator may require that you enter a billing code or authorization code (or both codes) after you
dial a phone number. The billing code, called a Client Matter Code, is used for accounting or billing purposes.
The authorization code, called a Forced Authorization Code, controls access to certain phone numbers.
When a billing code is required, the phone displays Enter Client Matter Code, the dialed number
changes to “********”, and you hear a
special tone.
When an authorization code is required, the phone displays Enter Authorization Code, the dialed
number changes to “********”, and you hear
a special tone. For security reasons, the phone displays a “*”
instead of the number entered.
When both a billing code and an authorization code are required, you are prompted for the authorization code
first. Then you are prompted for the billing code.

Secure Calls
Your administrator can take steps to protect your calls from tampering by people outside your company. When
a lock icon is displayed on your phone during a call, your phone call is secure. Depending upon how your
phone is configured, you may have to sign on before you make a call or before a security tone plays over your
handset.
