Nortel Line-Side T1 24 analog channels to Digium 4 port T1

I have a Nortel option 81c that I have programmed up a line side t1 card to use all 24 ports (no PRI because my switch software isn’t licensed for it) I have set the digital card for FXOLS and framing for esf/b8zs, Take timing, and the first option m(0-133 feet) for line build out field. also used all 24 channels. I then went to the users and set them up with their proper channel on the t1 but I get nothing, any ideas?
