[cisco-voip] Strange 800 number calling issue

I have 2 phones at a remote location trying to call 800 numbers. One phone
is a 7940 and one phone is a 7985. Both phone configurations from a
css/location/dp perspective are identical, however the 7985 is unable to
make a 800 number call. I have determined the failed call is receiving a
q931 disconnect message from the pstn. The only difference I see in the q931
debug from the vgw is the "transfer capability" of "digital unrestricted" on
the not working 7985 vs "speech" on the working 7940. Please see the
attached debug isdn q931, the top output is from  calling number
"5733481329" is the not working, the disconnect message got dropped from the
screen shot.
Thoughts appreciated.
