Call Waiting

Call Waiting provides cues to notify you that a new call is ringing on your phone when you are talking
on another call, including:
A call waiting tone (single beep)
An amber flashing line button

Respond to a Call Waiting Notification

(Your system administrator must set up multiple lines on your phone before you can use this feature.)
To answer the ringing call, press the flashing amber line button. Your phone puts the original call on
hold automatically and connects the ringing call.

cBarge

The cBarge feature allows you to create a standard (ad hoc) conference by adding yourself to a call on
a shared line.

Add Yourself to a Conference on a Shared Line

Press the line button of the shared line that is in use. If Privacy is enabled, you will not be able to add
yourself to the shared line.

Codes

Codes allow you to place a call using a billing or tracking code. Your phone supports two types of
codes (provided by your administrator):
Client Matter Codes (CMC) require you to enter a code to specify that the call relates to a specific
client matter. Your administrator can assign client matter codes to customers, students, or other
populations for call accounting and billing purposes.
Forced Authorization Codes (FAC) allow you to manage call access and accounting. The Forced
Authorization Codes feature requires that the user enter a valid authorization code before the call
connects.
