Regional Tab Media Loopback Code Referral Services Codes Chapter 5 SPA900 Series Phone Field Reference The star code used for enabling media loopback on the phone. The default is *03. These codes tell the 900 Series phone what to do when the user places the current call on hold and is listening to the second dial tone. One or more *code can be configured into this parameter, such as *98, or *97|*98|*123, and so forth. Max total length is 79 chars. This parameter applies when the user places the current call on hold (by Hook Flash) and is listening to second dial tone. Each *code (and the following valid target number according to current dial plan) entered on the second dial-tone triggers the 900 Series phone to perform a blind transfer to a target number that is prepended by the service *code. For example, after the user dials *98, the 900 Series phone plays a special dial tone called the Prompt Tone while waiting for the user the enter a target number (which is checked according to dial plan as in normal dialing). When a complete number is entered, the 900 Series phone sends a blind REFER to the holding party with the Refer-To target equals to *98. This feature allows the 900 Series phone to hand off a call to an application server to perform further processing, such as call park. The *codes should not conflict with any of the other vertical service codes internally processed by the 900 Series phone. You can empty the corresponding *code that you do not want to 900 Series phone to process. 5-26 Linksys 900 Series IP Phone Administrator Guide Document Version 3.0
