I've looked at one or two manuals & can't find anyway of modifying that delay - the one thing I haven't been able to find so far is a detailed description of the Sportsters S registers.

If what he wants is some noise recording, how about the following :

ATDT1234567;A+chr(13)

That will dial the number, drop back to command mode & then return immediately in Answer mode & go through the negotiation tones.
He could then delay as long as he wanted & then hang up.
