I would suspect that the PRI's (or some path to the PRI's) is not
configured for data calls (ISDN).  I went throught this *exact*
same thing with a 4048, a PRI, and BA.  :)  The sure way to tell is
to watch the ISDN cause code being handed back to your ISDN
TA.  With the 3com Impact this is very easy.  Just use the software
that comes with the Impact, and use the diagnostic (test) feature to
watch the traffic on the D channel.  My guess is that you'll get
back one of the following cause codes, or a similar one.
  65 - Bearer service not implemented
  88 - Incompatible destination
