Using Star Codes
Your IP phone can support numerous “star codes” to access phone
supplementary services. These codes, which start with *, are entered before
dialing a telephone number and provide services. For example, to block caller ID
(star code 67), you would dial *67, followed by the telephone number you are
calling.
Following is a list of commonly-used star codes. Some star codes may not be
available to you; consult your system administrator for more information.
