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:
Code Definition
03 Request media loopback for a call to monitor Voice over IP quality.
16 Activate Secure Call feature for all calls.* See Using Secure Call,
page 68.
17 Deactivate Secure Call feature for all calls.* See Using Secure Call,
page 68.

page 68.
