[asterisk-users] hang up detection

[Matic]

Of course it does provide quite descent hangup notification (425Hz 200ms 
200ms envelope for 40s), but it is asterisk/digium that in about 5% 
fails to detect it. I have trie to alter Tx, Rx gain and I even change 
the busy counter to value 2. Normaly it does detect hangup in about 2 
seconds but for whatever reason in about 5% it fails to do so. After 
40sec of hangup notification telecom also provides current off 
notification but I donb't know how to instruct asterisk to also detect this.
