Thank Martin,<div><br></div><div>That makes absolute sense. I have turned busy detect off for now and haven't heard complains or lines remaining open for a Day. I am in Canada. I just checked chan_dahdi.conf and I don't see callprogress there at all. So, I guess the lines are fine for hanging up by themselves. Hope this doesn't give me probs in future.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Either turn off busydetect or increase the busycount to 5-7 or even<br>
more ... (10 should be conservative)<br>
busydetect looks for cadence or patterns of the same length ... beep<br>
on [X ms] beep off [Y ms]<br>
so you can afford to increase busycount and have a few second longer<br>
calls / the line is kept longer offhook<br>
but you don't get false busy detections<br>
<br>
Also in US/Canada callprogress will do a better job then busydetect<br>
since it looks for specific frequencies of the busy signal<br>
and not just noise/beep then silence ... If you're somewhere else then<br>
you can hire a coder to tweak callprogress algorithm<br>
to your country's busy signal frequencies ... Just record the busy<br>
signal with ztmonitor and send to someone for code patch...<br>
<br>
