[Asterisk-Users] When 486 ATA crashes, asterisk does not disconnect the call

[Joel Jn-Francois]

Hi,

On several occasions one or more of our grandstream Handy tone 486 ATA 
would crash.  If for some reason that ATA is not rebooted immediately, 
asterisk would not disconnect the call, even though the party on the other 
end of the call have already hung up the call.  The call would continue via 
my asterisk server and my sip termination provider indefinitely until I 
either reboot the ATA device or restart asterisk.  It even ignores the 
timeout setting for the call. Can anyone explain why that would happen and 
how I can resolve that problem.

Thanks

Joel
