No Idea! This is not a programming forum.

However, MSDN does have Tapi related documentation, etc.

Never used that directly but I have used many calling macros with
parameter passing.
You have to make very sure that the params of the calling module match
those expected in the called one to a t.
Eg.
Called-module %A,%B,%C<%D,%E,%F,%G

If you want to use the default values apart from the last one, make sure
you have enough commas;
Call Called-module ,,,,,,123.
