I tried listening at work and I finally got to hear it. It sounds like Patsy in the background -- maybe a gasping sound one would make while crying. I don't know about the clicking noise. I think Ladybug's suggestion was the best I've heard so far.

One thing that I noticed, though, is that Patsy had OBVIOUSLY been running throughout the house -- up and down stairs -- because she was not just upset, but she was somewhat winded.

I would think that if they had planned the whole thing (coverup, or whatever, which is crazy) then she wouldn't have been running around before making the call.
