[Asterisk-Users] zt hook failed: Device or resource busy

[Eric Wieling]

I'm getting the message "zt hook failed: Device or resource busy". 
Not all the time, just sometimes.

As you can see it seems to happen when a port is hung up and then 
picked back up within 1 second.  What /etc/asterisk/zaptel.conf 
options might I use to fix this?  debounce=?  flash=?  something else?
