Hungup problem on incoming call in ringing state!

asterisk does not hang up the line on Zap channels only when its incoming and still ringing, all other situations work perfectly.

I have these features set in zapata.conf


any help would be appreciated

What card??? who are the lines from??

TDM400 with 4 FXO lines

check with the telco for the supervised disconnect or whatever they call
on those lines
get the the phone wiring is correct

The Foneguy says check for the OHM on the lines said some lines or to hot or to weak (check at the jack as it meets the card.
ask telco for specs
