Configuring Supplementary Services (Star Codes)
The Cisco IP phones provide 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.
Interdigit Long
Timer
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.
Interdigit Short
Timer
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.
