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

Example: *981135.

hold (h)
waitconnect (wc)
pause <number of seconds> (p <num

Example: 4411$Cwc$$Cp10$ defines dialing
4411>>waitconnect>>connected and lasts 10 seconds.
$T<type>$
The embedded action type. Multiple actions can be

refer
Example: *338$Tdtmf$ defines sending the *338 by the
