I had:

exten => _NXXXXXX,1,Dial(SIP/@2003,60,D(w$EXTEN}))
exten => _NXXXXXX,2,Hangup

Where 2003 was the extension of the FXO on the HT-488.  This worked ok 
for dialing 7 digit calls to the FXO, but also had a weird double (one 
after the other) ringback?

Also use dtmfmode=RFC2833 in the extension and set the HT-488 the same.

I had to give up on that device due to poor audio quality and echo 
issues .  Also intermittent hanging made this device unacceptable for 
me.

Let us know if it works for you?  Also which firmware and asterisk 
version are you using?
