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.<br>

<pre wrap="">Hi,
I have a small problem with tdm2400 with tone detection. About 5% of all
calls doesn't end because Asterisk dosen't detect "busy" tone on remote
hangup. I know that board does support current reversal and current off,
but how do I configure asterisk to use tone detection first and if that
should fail, current off detection which my operator support (40 sec
after remote hang up).

Just for the record: which telco is it? Doesn't it provide decent hangup
notification?
