Funny... as you copied me on the email...

Correct, as DADHI assumes that the call has been answered just as soon
as the last digit has been sent, so the length of time the phone rang
before being answered would determine how much of the message was
missing.

Correct, because cell phones often have a longer call setup time than
pots lines.

Correct, because the SIP channel driver knows when the call has actually
been answered.  Please go back and re-read my previous message... it
explains why you're seeing the behavior that you've explained here.

The only reason I can think of that this would be happening is if you
happen to have "callprogress=yes" in chan_dahdi.conf on your live
system.  Please note that the callprogress setting is *highly*
experimental, and in my experience causes more problems than it's worth.
