Chris, the problem is that you went from PRI to channelized T-1.  In PRI
world, the D channel does all of the signaling and call setup so it tells
the max whether or not the incoming call needs to be routed to the digital
control processor on the max for an ISDN call or to a modem for an analog
call.  The default setting to allow this is slot=0.  Now you have switched
to a Channelized T-1 and there is no D channel to tell the max how to handle
the call.  Now you must tell your max what slot your modems are on so it can
hand of the call to an analog modem.  To do this, you need to have all of
the channels on the max set to "ch 1 slot=3", "ch 2 slot=3" and so forth for
all 24 channels on the T-1.  setting as below.

Also, you must make sure that your Telco is not sending any CLI/ANI or any
digits across the T-1.   If they are, you will still get the same busy
signal because the max doesn't know what to do with that information so it
returns a busy signal.   It is an obscure statement in the users manual that
drove me nuts for a month on a test machine before I finally found it.
