Thank you very much for that report!  I was hoping that someone
would post something like that (even though I am about to test it
out here for myself since I'm now pretty sure I can do it).

The nice part about my installation is that I don't have to worry
about that stumbling block.  My max4048 terminates only ISDN
callers, and all analog modem cards have been removed.  Therefore,
my max does not need to be able to distinguish between call
types, because it handles all incoming calls as ISDN data calls.
We did this in order to terminat DOV (Data Over Voice), so that
our users could make their data calls 'look' like voice calls
(at 56kbps) so that they could avoid paying $.01/minute/channel
which is charged by the telco for data calls.  Now we just
want to go one step further and replace our $750/mo T1/PRI
with a $210/mo CT1.

I  know what you mean... I have been down that road more than once... which
is why I'm very glad that I don't think I need to for this particular
case.  :)

Thanks again for the excellent info!
