Cisco IP Phone Troubleshooting
Parameter
Feature Dial Services Codes
Description
These codes tell the 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, and so
forth. The maximum total length is 79 characters. 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 phone to call the target
number prepended by the *code. For example, after
user dials *72, the phone plays a prompt tone awaiting
the user to enter a valid target number. When a
complete number is entered, the 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
phone. You can empty the corresponding *code that
you do not want to the 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 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 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 phone sends INVITE *73@.....
as usual when user dials *73.
