[cisco-voip] VG224 Issue / propable misunderstanding

[Kevin Thorngren]

Hi Bernhard,

The behavior you describe is pretty much what I would expect.  The busy 
tone you hear should be fast busy (reorder) and not slow busy (user 
busy).

The CCM is signaling the voice port to go on hook when the call is 
disconnected.  The FXS device is expected to hang up.  If it does not 
then one of the GW timers will expire and reoder tone will be played.  
Since the voice port is still off hook another timer will then expire 
and the GW will take the voice port off hook.  You are probably hearing 
the annunciator because CCM is waiting for digits and does not receive 
any.

What does your device expect for disconnect supervision?
