One of the solutions is:

DECLARE LONG tapiRequestMakeCall IN "TAPI32.DLL" ;
		STRING cTel, ;
		STRING cApp, ;
		STRING cUser, ;
		STRING cComment

lcTel = Phone_number
lcApp = "Application NAme"
lcUser = "Calling to "+lcTel 
lcComment = "Comments go here"

= tapiRequestMakeCall(lcTel, lcApp, lcUser,lcComment)
