I have an Asterisk box on a Debian distro with mISDN drivers.
I installed the new driver (0.3.1-rc30) on our pbx but since no voice 
was passing I decided to go back to old version (0.3.1-rc23).
Last friday everything seemed to work fine but now  every  incoming  
call  drops  after 3-4 seconds while Asterisk console is showing these

Is there anybody who can help me?
Thank you all.
