<div dir="ltr">Hi Xavier,<div><br></div><div>The issue you are seeing is an old Asterisk/Bristuff bug that was fixed years ago.</div><div><br></div><div>Basically ISDN is unable to understand a call going from RING state to BUSY state, so Asterisk converts the BUSY into a HANGUP/Normal Clearing, and warns that this is happening.</div>

We use an IPcortex PABX running Asterisk 1.2.39-BRIstuffed-0.3.0-PRE-1y-y. We have recently implemented Call Queuing for our main incoming line with hold music. The call queue type is: Ring all - One call at a time (no position announcement).<br>
<br>
Since implementing this feature we've been receiving the below error daily in the mornings and lunchtime when the queue will jump to the next available phone, as the main reception phone is in Do Not Disturb mode:<br>
<br>
Jul 11 08:30:54 WARNING[23444] chan_zap.c: 1 Cause code 17 not allowed when disconnecting an active call. Changing to cause 16.<br>
Jul 11 08:30:54 ERROR[23444] chan_zap.c: You cannot use cause 17 number when in state 6! Corrected.<br>
Jul 11 08:30:54 WARNING[7133] chan_zap.c: Call specified, but not found?<br>

Jul 11 08:47:23 WARNING[7133] chan_zap.c: 1 received SETUP message for call that is not a new call (retransmission), peercallstate 19 ourcallstate 0 cr 1,<br>
<br>
The ERROR happens when the call is ended. I can't replicate the error either...<br>
<br>
I suspect that the chan_zap driver has a bug and is possibly trying to hang up the call on the first phone in the queue, rather than the phone that answered the call.<br>
<br>
I have investigated the different state and causes listed in the above log file, and this is what I think they mean (please correct me if I got it wrong):<br>
ISDN State 6 = not initialised<br>
Cause 16 = normal call clearing<br>
Cause 17 = user busy<br>
TEI 127 = reserved as the broadcast TEI<br>
<br>
<br>
So my questions are:<br>
1. What could be causing the error and any suggestions on how to troubleshoot this issue?<br>
2. Can I upgrade the chan_zap driver for the ISDN card without breaking the IPcortex frontend (we have root access)?<br>
3. Should I supply any config files?<br>
<br>
<br>
Thanks!<br>
Xavier<br>
