If you are using libpri-1.4.4, you should either downgrade to 1.4.3 or 
upgrade to 1.4.5.  A new default behavior was introduced in 1.4.4 (which 
should have been optional, not default) which causes a channel to be 
left open until the RELEASE timer expires when a DISCONNECT is received 
with Inband progress information avaiable.
