I agree - It sounds like a data exchange. I might be incorrect, but I do not believe so.
The sound kind of reminds me of the old 1990's "dial up" modems.
The sound is not constant like a digital or encrypted voice transmission.
The sound is interrupted in intervals......and there is no specific timing, or regular timing in the intervals.
My bet is on a data transmission.
