Using Star Codes
The SPA525G 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:
