Feature Dial Services Codes These codes tell the IP phone what to do when the 
user is listening to the first or second dial tone. 
One or more *code can be configured into this 
parameter, such as *72, or *72|*74|*67|*82, etc. Max 
total length is 79 chars. This parameter applies when 
the user has a dial tone (first or second dial tone). Enter 
*code (and the following target number according to 
current dial plan) entered at the dial tone triggers the IP 
phone to call the target number prepended by the 
*code. For example, after user dials *72, the IP phone 
plays a prompt tone awaiting the user to enter a valid 
target number. When a complete number is entered, 
the IP phone sends a INVITE to *72<target_number> as 
in a normal call. This feature allows the proxy to 
process features like call forward (*72) or BLock Caller 
ID (*67).
The *codes should not conflict with any of the other 
vertical service codes internally processed by the IP 
phone. You can empty the corresponding *code that 
you do not want to IP phone to process. 
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‘. Below are a 
list of allowed tone parameters (note the use of back 
quotes surrounding the parameter w/o 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 IP phone plays 
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, simple add that *code in 
the dial plan and the IP phone send INVITE *73@..... as 
usual when user dials *73.
