For completeness of the archives, I've found the answer to this. 

I've had to move from dtmf = rfc2833 to dtmf = info to fix my problems.  
The only issue now is that Asterisk doesn't recognize dtmf for the local 
phone system's voice mail.  I get around that by setting only the 
conference room phones to info and everybody else to rfc2833
