My integration is really awful, due to a couple of factors...a) it was 
set up using CCM 3.1 and Avaya Definity G3R v6, neither of which had 
any Q.SIG support; and b) all of our gateways to this point are H.323 
(this will change with our wider deployment); 

DTMF does work fine.  Essentially the two systems share an overlapping 
dial plan due to the business's reluctance to make people change phone 
numbers.  As such, I have a 4-digit H.323 dial peer for each station, 
which handles both inbound and outbound calls.

The gateway is a 3640, which also handles a small DSP farm for Xcoding 
and CFB.  It should also be going away soon in favor of one of the ISR 
gateways, likely a 2841.
