[asterisk-users] Asterisk dont detects hangup by phone

[ABBAS SHAKEEL]

Hello
I have configured TDM400P with asterisk .
The problem is that when i make a call to server. and while going on
it dont detects call hang up.

ie i called the Asterisk server and it start playing files that i
indicated to do so in extensions.conf
i suddenly put down the phone. now the server must detect that phone
is hangup but it dont.

How can i make server to detect this
