Using Star Codes
The Cisco SPA 525G supports 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 supported star codes:
