Sounds like you did well with your reply. I'm sure he didn't pick up because he didn't like the fact that you didn't answer when HE called.
Now you have to decide whether to keep playing phone tag or answer the phone next time he calls.
One thing to be wary of. He may have sensed (or heard--or read??) that you are thinking of filing for D. Calling and mentioning papers that aren't quite right sounds like a good way to stall. You were ready to file, and now you are back to waiting for him to fuss with these papers.
