Sounds like your having a problem with pstn disconnect supervision. Not
sure how disconnect supervision works in your country, but here in the
US it is an opening of the pstn line (no voltage) for something less
then a second. Some countries use tones for this purpose. You'll need
to find out what the standard is and (hopefully) set asterisk to 
recognize that method.
