If you can capture the q931 debugs that show the requested
circuit/channel you can have a much more focused discussion with the
pbx tech.<br>

<br>
The B-Channels on my router are all in service, the only problem is
that I don't have visibility on the Alcatel PABX, we are making
arrangements with the vendor to investigate. We have access to all 30
channels on the PRI from what I understand. We'll have a look at the
channel selection order on the Alcatel PABX. Thanks for the assistance.<br>
<br>
Kind regards,<br>

<div bgcolor="#ffffff" text="#000000">So either an invalid channel
was selected or one was selected that was
already in use.<br>
invalid channel - only reason this typically happens is that B-channels
are taken out of service. Are the b-channels out of service for some
reason? is this a fractional PRI where only some b-ch are used?<br>
already in use - this is called "collision" and is usually mitigated by
using opposing channel selection order on the CO and provider
equipment. One does top down, the other bottom up.<br>
<br>
observing 'debug isdn q931' for a while prior to the error would allow
you to track the state of things and clarify why the error is happening.<br>

<div class="h5">Hi,<br>
<br>
I have a 3825 router connected to a Siemens HiPath PABX with a QSIG. My
Cisco IP Phones place calls to the PSTN though the QSIG trunk. I've
been having intermittent errors with placing calls through the trunk,
and I've picked up the following error through debugs:<br>
<br>
**ERROR**: CCPMSG_OutCall: fails with cause 0x22<br>
Cause i = 0x80A2 - No circuit/channel available<br>
<br>
I don't think its over utilization, I checked the channels in use and
only a third were active. Does anyone know what could be causing this.<br>
<br>
Kind regards,<br>
<br>
