A couple of links for you to have a look at :-


Basically the best way would be to contact your carrier and ask if they can add disconnect supervision to the line.

I have the same problem on my home server but its mainly due to the cheap clone x100p single port alanogue interface I use. Mine doesnt seem to detect a hangup but after a minute the telco plays a message saying to hang up and then an error tone which the card does recognise and hang up. Only ever an issue for voicemail and you can configure voicemail with a maximum recording time limit.

Its well worth specifying a maximum recording time limit anyway. Once at work someone phone our customer services at night and didnt put the receiver down properly. In the morning we had a 5 hour answerphone message. I set a limit after that :) Luckily (for us) it wasnt a freephone number.
