You can add a parameter to each * code in 
Features Dial Services Codes
 to 
indicate what tone to play after the * code is entered, such as *72‘c‘|*67‘p‘. 
Following is a list of allowed dial tone parameters (note the use of back 
quotes surrounding the parameter without spaces).
-  ‘c‘ = Cfwd dial tone
-  ‘d‘ = Dial tone
-  ‘m‘ = MWI dial tone
-  ‘o‘ = Outside dial tone
-  ‘p‘ = Prompt dial tone
-  ‘s‘ = Second dial tone
-  ‘x‘ = No tones are place, x is any digit not used above
If no tone parameter is specified, the Cisco IP phone plays the prompt tone 
by default.
If the * code is not to be followed by a phone number, such as *73 to cancel 
call forwarding, do not include it in this parameter. In that case, add that * 
code in the dial plan.
Activating or Deactivating Supplementary Services
You can disable services handled locally by the phone in one of two ways: 
• Delete the star code in the
 Vertical Service Activation 
section in the Regional 
tab.
• Disable the service in the 
Phone
 tab. See Configuring Supplementary 
Services (Star Codes), page 180.
If a service is enabled in the Phone tab but cleared in the Regional tab, the service 
can still be enabled/disabled from the IP phone screen or the phone web user 
interface. If a service is disabled, the soft button associated with that service is 
hidden on the IP phone screen. Also, any menu item associated with a disabled 
service is preceded with an exclamation mark (!). 
A supplementary service should be disabled if 
• the user has not subscribed to it 
• the service provider intends to support similar service by using means 
other than relying on the Cisco IP phone.
