in the rdb MIGHT help, if they are loop, they will hang.. you can deny hook flash in the cls.. and adjust the timers in the rdb and stop most hang ups.. if you know the max talk time, you can use tfd timer which will idle the trunk after x number of seconds.. i am using timed forced disconnect on some courtesy phones and over page access.. each disconnects after 3 minutes..

An interim solution is to set the Route Data Block TIMR "TFD" value (1 to 3600 seconds) which will "at least" disconnect the connection when the timer value is reached.

If few or no calls exceed 60 minutes (TFD 3600) few or no people would be inconvenienced if the system disco'd calls (and free's the locked up trunks) every 60 minutes.

It is not a "fix" but rather a crutch until the real fix is found.
