asterisk users - May 2004 - need working loopstart config - t100p

I am connecting a t100p to a b8zs, superframe, loopstart t1. Previously
I've attached to e&m wink and pri lines with no problems; however I seem
to be missing something.

Should it be fxols in the zaptel.conf (smartjack to x100p) or
fxsls?

With e&m wink the dnis set was 100, so it was easy to make an extension
100; and it would answer incoming calls. How do you get a loopstart to
answer incoming calls?

Thanks,
