Normally a hangup at the b-subscriber (the receiving end) does not tear 
down the call immediatly, at least not for analog lines from the incumbent 
operator here in Sweden. I think it is something like 10-30s until the 
call is released in that case. Did you call an analog phone and how long 
did you leave it on hook?

You need to set up debugging in the corresponding conf file for Asterisk. 
Debugging of the PRI signalling is then set up with
  pri debug span ??? 
or
  pri intense debug span ???
