That's what I've read, and I have added dtmfmode=rfc2833 in my
sip.conf...see this snippet:

[xlite1]
;Turn off silence suppression in X-Lite ("Transmit Silence"=YES)!
;Note that Xlite sends NAT keep-alive packets, so qualify=yes is not needed
type=friend
username=xlite
callerid="Jane Smith" <5678>
host=dynamic
nat=yes                       ; X-Lite is behind a NAT router
canreinvite=no                ; Typically set to NO if behind NAT
disallow=all
allow=gsm                     ; GSM consumes far less bandwidth than ulaw
allow=ulaw
allow=alaw
dtmfmode=rfc2833

I've applied that change and restarted asterisk, but no dice...
