I've been running a TDM04b since they first came out. Had to RMA one due
to its 'early' version about a year ago, but the Rev I card now installed
is stable (as in no dropped calls). I've been running various Head versions
over the last two years in purely stock source code form with no call-
drop problems.

I'd suggest running ethereal on the LAN side with a mac address filter of
your loud talker's phone. The next time it drops the call, stop the trace
and look at the sip packets to see if asterisk is telling the phone to 
hangup or whether the phone (or connections) failed, etc.

If you can't read an ethereal trace, send the last 100 or so packets to
me off list and I'll help you with that part.
