Maybe you want to try ISDN4BSD? It has better guarding against ghost-calls 
than libpri. Actually ISDN4BSD will check the state of the call every 8 
seconds, and if you hungup and it was not detected it will hangup the call, 
when it finds out that the call is no longer there.

The QuadBRI ISDN card is supported by ISDN4BSD, if you download the SVN 
version. See: 

http://www.selasky.org/hans_petter/isdn4bsd/

Quick download:

If one has got Subversion installed, the latest sources can easily be obtained 
by running the following command: 

svn --username anonsvn --password anonsvn \
      checkout svn://svn.turbocat.net/i4b
#
# The following commands will 
# install the driver on FreeBSD:
#
cd i4b/trunk/i4b/FreeBSD.i4b
make S=../src package
make install

Then you install the new version of "chan_capi". See:
http://www.selasky.org/hans_petter/capi4pbx/index.html

svn --username anonsvn --password anonsvn checkout \
    svn://svn.turbocat.net/i4b/trunk/chan_capi

There are example configuration files coming with "chan_capi", namely 
"capi.conf" and "extensions.conf".
