Note
Configuring the Call Waiting
You can enable or disable call waiting on the phone. If call waiting is enabled, you can receive
another call when there is already an active call on the phone. Otherwise, another incoming call
is automatically rejected by the phone with a busy message when there is an active call on the
phone. You can also enable or disable the phone to play a warning tone when receiving another
call.
Procedure:
1. Navigate to Menu->Features->Call Waiting.
2. Select Enabled from the Call Waiting field.
Auto answer only takes effect when there is no other call in progress on the phone. If there is a
call in progress, the second incoming call cannot be automatically answered after ending the
current call by default. If you want to make the phone automatically answer the incoming call
after ending all calls, contact your system administrator for more information.
