I answered my own question. My objective was reached with a simple
return statement on line 4384 of chan_sip.c in asterisk 1.2.9.1 ftp

200 OK that indicates in the SDP that only inband DTMF is
supported. My carrier detects this and their NexTone Session
Switch sends out dtmf inband.
It sucks having to force asterisk to operate in this manner, but
hopefully asterisk implementation of rfc2833 will get the bugs
worked out, if they are in fact bugs, and not design desicions.
So a simple:
dtmfmode=inband
In the appropriate extension (your outbound call terminator) wasn't
adequate to force the proper 200 OK message? This doesn't seem like
something you should need to change code to do?
Glad it's working anyhow, and thanks for sharing your hack.
