If you mean something like

	void foo(int);

	main()
	{
	    foo(int i = 12);	 // valid?

that has never been allowed as a function call. (The example is
a valid construct, but it re-declares 'foo' to have a default
argument of value 12. It is not a function call.)
This example shows one reason why it isn't allowed: ambiguity.

A function call contains a list of expressions, and an expression
cannot contain a variable definition. (The "condition" part of a
selection statement or loop may now contain a variable definition,
but those are not expressions.)
