[Asterisk-Users] Detecting disconnect on TDM400P with 3 FXO ports and 1 FXS port

[Cosmin Prund]

Hellow everyone, here's an other newby question.

I've got a * configured with the card in the subject line. At times Asterisk
fails to notice a disconet from the incoming line going into one of the FXO
ports. Consequently it just keeps the line off-hook for ever and that causes
my provider to mark the line aut of order.

Is there any way to "help" Asterisk notice the disconect?
