Assuming that you mean a PRI when you say 23 channels as it is unlikely
that you would have installed 23 of 24 channels of a channelized T1. 

With PRI, your DID info and anything else on call setup is in the
D-channel on channel 24. Since any of the 23 B-channels could be your
FAX line, you can not use drop and inserts. 

With a PRI and with most of your FAXes being inbound, why aren't you
using rxfax? It eliminates anything outside of asterisk and the T100P
card. You do not need Hylafax.

As for Hylafax and the T100P card. Faxes are sent with analog modems,
the T100P card does not provide any methods of dealing with the data
inside the analog modem stream. All the T100P card and asterisk care
about is getting the audio data moved around. Oh, an Hylafax doesn't
provide an analog modem either.

If you must use an old dead tree processing fax machine, you either need
to get an analog adapter or another T1 span and a channel bank to
provide the analog port. 

Another alternative is one of the T1 fax boards where you could just use
a new T1 span and cross over cable to the fax card.
