+		I have absolutely *NO* clue as to why the following was a
+		conditional. It caused a bug in which the WRONG call would
+		get hung up on in certain situations after a 3-way call. It
+		took us over *3 YEARS* to find out the exact conditions to
+		make the problem appear (which are first leg of call, inbound
+		or outbound is answered, you go over to a 3-way dialtone and
+		make a second call, then flash again before the second call
+		has answered (the channel going into STATE_UP condition).
+		Then, when you flash again, then first (original) call would
+		get dropped instead of the second one like it should.
+
+
+	I left the following conditional here (commented out, of course) so
+	that if theres any further issues with this, its here.
