Configuring Regional Parameters and Supplementary Services Configuring Supplementary Services (Star Codes) 8 Field Interdigit Long Timer Interdigit Short Timer Description Long timeout between entering digits when dialing. The interdigit timer values are used as defaults when dialing. The Interdigit Long Timer is used after any one digit, if all valid matching sequences in the dial plan are incomplete as dialed. Range: 0-64 seconds. Setting this value high can result in a longer post dialing delay (PDD), which is the time between the start of a call and the time the phone starts ringing. A value that is too low can result in dialed digits not being correctly recognized. Defaults to 10. Short timeout between entering digits when dialing. The Interdigit Short Timer is used after any one digit, if at least one matching sequence is complete as dialed, but more dialed digits would match other as yet incomplete sequences. Range: 0-64 seconds. Defaults to 3. Configuring Supplementary Services (Star Codes) The Cisco IP phones provides native support of a large set of enhanced or supplementary services (also known as star codes). A user can enter star codes (such as *21 for call forward, followed by the target number) to perform call features such as call return, blind call transfers, call pickup, and so on. These codes can be handled locally by the phone or to be sent to the network as an INVITE to the service provider. NOTE: Some service providers choose to disable star codes. See "Configuring Supplementary Services (Star Codes)" section on page 153. Entering Star Code Values The phone provides default values for star codes. You can change the default star code values for your area or region. Cisco SPA and Wireless IP Administration Phone Guide 153
