C
Resets the Call Detail Record for the call. Since the CDR time is set to when you
Answer() the call, you may wish to reset the CDR so the end user is not billed for
the time prior to the Dial() application being invoked.

d
Allows the user to dial a one-digit extension while waiting for a call to be answered.
The call will then exit to that extension (either in the current context, if it exists,
or in the context specified by the EXITCONTEXT variable).
D([ called ][: calling ])
Sends DTMF digits after the call has been answered, but before the call is bridged.
The called parameter is passed to the called party, and the calling parameter is
passed to the calling party. Either parameter may be used individually.
f
Forces the Caller ID of the calling party to be set as the extension associated with
the channel using a dialplan hint. This is often used when a provider doesn’t allow
the Caller ID to be set to anything other than a number that is assigned to you. For
example, if you had a PRI, you would use the f flag to override any Caller ID set
locally on a SIP phone.
g
Execution of the dialplan goes on in the current context if the destination channel
hangs up.
G( context ^ extension ^ priority )
When the call is answered, the calling party is transferred to the specified priority
and the called party to the specified priority+1. You cannot use any additional
action post-answer options in conjunction with this option.

h
Allows the called user to hang up the channel by pressing the * key.
H
Allows the calling user to hang up the channel by pressing the * key.
i
Causes Asterisk to ignore any forwarding requests it may receive on this dial
attempt.
j
Causes Asterisk to jump to priority n+101 if all the requested channels were busy
(where n is the current priority).
L( x [: y ][: z ])
Limits the call to x milliseconds, warning when y milliseconds are left and repeating
every z milliseconds until the limit is reached. The x parameter is required; the y
and z parameters are optional. The following special variables may also be set to
provide additional control:
