By default the transmitted phone number is your default number.
To use a different phone number:

  • Select a different number in the CLIP internal and CLIP external fields.
  • You will be offered phone numbers which the administrator has entered as additional numbers for your user name.

Enable or disable Call waiting
Enabled: Calls that come in while you are on the phone are indicated by an audible signal.
Disabled: Incoming calls while you are on the phone are not indicated by an audible signal.


You can also enable and disable caller ID blocking and call waiting in the home screen of the user interface. The switch in the home screen enables/disables caller ID blocking for internal and external calls.

You can also set call waiting and caller ID blocking directly using the keys on the phone itself
