Understanding Macro Action Strings
Before using EDK, you must be familiar with macro language shown in this section.
The following table shows the basic macro action string syntax when creating EDK macros:
Macro Action
Description
Digits
The digits to be sent. You can use only *, #, +, 0-9. The
appearance of this parameter depends on the action
string.
Example: *981135.
$C<command>$
This is the command. It can appear anywhere in the
action string. Supported commands (or shortcuts)
include:
 hang up (hu)
 hold (h)
 waitconnect (wc)
 pause <number of seconds> (p <num
sec>) where the maximum value is 10
Example: 4411$Cwc$$Cp10$ defines dialing
4411>>waitconnect>>connected and lasts 10 seconds.
$T<type>$
The embedded action type. Multiple actions can be
defined. Supported action types include:
 invite
 dtmf
 refer
Example: *338$Tdtmf$ defines sending the *338 by the
type of dtmf.
Note: We recommend that you always define this field. If
it is not defined, the supplied digits are dialed using
INVITE.
$M<macro>$
The embedded macro. The <macro> string must begin
with a letter. If the macro name is not defined, the
execution of the action string will be ignored.
Example: $MAA$ means invoking the EDK macro AA.
$S<softkey ID>$
The functionality of performing this action is the same as
that of pressing the desired soft key.
Each soft key has a unique identifier on the IP phone, you
can configure this parameter according to the system-
