AT&T's IVR to collect the passcode is coming through as "early media"
and since you haven't signaled to the phones that the phone is
"answered" they're probably not letting you send DTMF through the
bridge that isn't technically supposed to be there yet.
Put an Answer() in your dial plan prior to sending the call out to
the Dial() application to reach the bridge for these types of calls
and this generally fixes your problems caused by someone else not
