	This wasn't the whole answer, but, as is usually the case, it was the 
thread that I tugged at and unraveled into a solution.

	I respond to the list only to archive this for future fiddlers with 
soft-phones.


	Apparently X-Lite is one of the few DTMF soft-phones available, and 
they've been actively working on RFC2833 support.  This is the default 
configuration.

	To restate, I'm using Asterisk + X-Lite on MacOSX.

	I found, deep in the advanced settings-->Feature Settings (different 
location than in the windows X-Lite client) the DTFM configuration 
toggles.

	I started by switching it to do in-band.

	That partially solved the problem, but ethereal traces were still 
showing a few extra (hit-n-miss) digits going at Asterisk, which caused 
VoiceMail to not find user/pass matches.
	
	I then toggled DTMF Tone Length to half the default value (2800 --> 
1400) and viola, things seem happy, consistently.

	As it turns out, if you turn in-band off, and let it revert bck to 
RFC2833, the reduction in DTMF Tone Length seems to solve the problem.

Thanks!
