It sounds like your gateway is in a different "location" than the phones.<br><br>Thats the only time CAC will get involved is when it is crossing between CM locations<br><br><div class="gmail_quote">On Fri, Jan 29, 2010 at 2:37 PM, O'Brien, Neil <span dir="ltr"><<a href="mailto:nobrien@datapac.com">nobrien@datapac.com</a>></span> wrote:<br>

<p class="MsoNormal"><span style="font-size: 10pt;">Hi,</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">I’m
going to try and explain this as best I can.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">We
have Call Manager 7 cluster in a centralised call processing model with 9
satellite sites. All outbound calls from each site breakout locally to
that site, be it via ISDN BRI or PRI.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">Each
route list for each site has a send entry for another site. In the event
local outbound calls fail, they will go via the WAN and breakout from the other
site.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">On
one site (I’m worried now that it might be on the other sites as well) I’ve
been troubleshooting for a while now an issue whereby when only one channel of
a BRI is being used, all the rest of the out bound calls start going out
through the other site, even though there is a second channel on the active BRI
and 2 other BRI (4 channels) available.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">Removing
the backup paths from the route list and using a single BRI I started debugging
and came to the conclusion that the second channel wasn’t being utilised
but after some more digging I realised that I was getting “Not Enough
Bandwidth” when a second call was attempted. This pointed me at
Call Admission Control.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">The
site in question only has a 128k link into it, and I have the location bandwidth
set accordingly. But when I up the bandwidth allocation or set it to
unlimited for that location, calls start going out on all BRI’s no problem.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">Now
I’m confused – I thought the CAC only tracked calls between
locations, deducting bandwidth accordingly. But for some reason, it’s
deducting 64K (an ISDN channel) from this locations bandwidth allocation, even
though the call is breaking out locally.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">I’d
appreciate anyone’s help on this. I don’t know yet if it’s
just this site, I’m going to start testing when I send this mail.</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">Thanks
in advance,</span></p>
