Macro Action Description
Example: 4411$Cwc$$Cp10$ defines dialing 4411 > > waitconnect > > con-
nected and lasts 10 seconds.
$T<type>$
The embedded action type. Multiple actions can be defined. Supported action
types include:
l invite
l dtmf
l refer
l intercom
Example: *338$Tdtmf$ defines sending the *338 by the type of DTMF.
Note: We recommend that you always define this field. If not, 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.
$S<softkey ID>$
It has the same effect as 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-defined softkey ID. If the softkey ID is not
defined on the phone or there is no matched soft key on the current screen,
the execution of the action string will be ignored. The softkey ID is case-insens-
itive.
Example: $Sanswer$ means pressing the Answer soft key.
Yealink phones support customizing soft keys. When the phone invokes a cus-
tom soft key, the prefix “#” must be added.
Example: If the custom softkey label is IVR1, the custom softkey ID is custom_
macro, then $S#custom_macro$ means pressing the IVR1 soft key.
Note: To view the softkey ID, you can set “features.enhanced_dss_key-
s.enable” and “edk.id_mode.enable” to 1 (Enabled) and then long press the
Volume Up key when the phone is idle.
$K<key name>$
The functionality of performing this action is the same as that of pressing the
desired hard key.
Supported key names include:
l LineKeyX (for T57W/T48U/T48S/T48G, X=29; for
T54W/T46U/T46S/T46G/T29G, X=27; for T42U/T42G/T42S/T41P/T41S,
