I am also facing the call disconnection if there is a third call. I tried disable call waiting in the BRI router, but now it has been reduced, it means call disconnection is not permanent but seems to be occasion, let say per day two times there is a call disconnection.<br>

I'm resending this email to the list, apparently the first one didn't go<br>
through. If it did, I apologize for the re-post.<br>
<br>
Hello,<br>
<br>
Following my first mail about this issue [1], I think I know now what<br>
the problem is.<br>
<br>
When I have both lines being used and a third call comes in, the person<br>
calling doesn't get a busy tone, he gets something like line unavailable.<br>
<br>
I've been debugging mISDN and I think the reason is because asterisk is<br>
sending the release cause as 0.<br>
<br>
P[ 3] --> channel:0 mode:TE cause:0 ocause:0 rad: cad:<br>
<br>
The request from the telephone company's switch seems correct, a SETUP<br>
message (if 08 is Q.931, 05 is SETUP).<br>
<br>
02 ff 03 08 01 04 05 a1 04 03 80 90<br>
a3 18 01 80 6c 0b 01 83 39 31 36 33<br>
39 31 37 34 32 70 03 c1 38 34<br>
<br>
I've changed misdn.conf so it sends a release cause as 17 (user busy),<br>
but I get the same behaviour - cause:0 ocause:0.<br>
<br>
Anyone knows how can I force asterisk to send cause 16 or 17 in this<br>
situation?<br>
<br>
Thanks in advance.<br>
<br>
Best regards,<br>
Paulo Santos<br>
