Spoofing ISDN

[Edward Maillet <maillet @ doc . cs . usm . maine . edu>]

Hey All,
  Some folks at work want to setup an ISDN dial-in connection relying
solely on the inbound caller ID as the security measure. Is it possible
to spoof the D channel to send fake info? I'm fairly certain there is
a way to do it. Can anyone point me to some references so I can make a
decent technical argument agaisnt this?
Thanx.
