Some features require different types of functionality such as additional dialed digits,
establishment of another call, and control of the feature key LED. Additional characters can
be added to the code string to enable this functionality. Following are some typical feature
“star codes” with additional characters:
CALL FORWARD activate *72#DIL (prompts for additional digits, then an
auto-originated INVITE is sent with *72 +
dialed digits; the feature key LED is turned
on)
CALL FORWARD deactivate *73#-IL (does not prompt for additional digits; an
auto-originated INVITE is sent with *73;
the feature key LED is turned off)
CALL PARK *98#DR- (prompts for additional digits, then
transfers the call to *98 + dialed digits)
CALL UNPARK *99#DC- (prompts for additional digits, then an
auto-originated call is placed to *99 +
dialed digits)
DIRECTED CALL PICKUP *53#DC - (prompts for additional digits, then an
auto-originated call is placed to *53 +
dialed digits)
GROUP CALL PICKUP *54#-C- (does not prompt for additional digits; an
auto-originated call is placed to *54)
The star code must be followed by a # character.
The three characters following the # are defined as follows:
Character 1 – capital letter D to prompt the user to dial additional digits
- (hyphen) if no additional digits are required
Character 2 – capital letter C to initiate an auto-originated two-way audio call
capital letter I to send an auto-originated INVITE without audio
capital letter R to transfer an existing call
- (hyphen) if none of the above is required
Character 3 – capital letter L to turn on the feature key LED when an 'activate' feature
code is sent, or turn off the feature key LED when a 'deactivate' feature
code is sent
- (hyphen) indicates no action
Note: If the LED is off when the feature key is pressed, the activate code
will be sent; if the LED is on, the deactivate code will be sent. Server
feature activation/deactivation may not be synchronized with the phone
feature key state (e.g. if the phone restarts due to a power loss). The
feature key LED only indicates the phone feature key state; it is not
guaranteed to indicate the server feature state.
