<div><font face="Arial" size="2"><span>Hi there,
</span></font></div>
<div><font face="Arial" size="2"><span>I have a number of
phones (20 out of 192 in one VLAN) that are coming up with CM Down during
calls. I know that this is caused through the phone being unable to talk to
the call manager via skinny, however we are having no phones rehome to
other Call Managers, and in the particular building we have 600+ users and this
is only affecting 20 users all of whom are in the same VLAN.</span></font></div>
<div><font face="Arial" size="2"><span>The VLAN configs are
all the same and deployed in the same manner across 8500 phones. There are 4x
3560-48 switches in the affected VLAN. </span></font></div>
<div><font face="Arial" size="2"><span>These connect via
GBIC uplink ports to redundant 6509 core switches.</span></font></div>
<div><font face="Arial" size="2"><span></span></font> </div>
<div><font face="Arial" size="2"><span>We are seeing no
errors on the WAN, or interfaces, in fact the only please the error is seen is
on the phones themselves, and it is intermittent. The IOS version is 12.2(25)sec
which again has been deployed on over 400 of these in the
network.</span></font></div>
<div><font face="Arial" size="2"><span>It seems link only
skinny is affected, the users are not complaining of data errors and the calls
are not being cut off, although the caller is reporting hearing a loud noise
when it happens.</span></font></div>
<div><font face="Arial" size="2"><span></span></font> </div>
<div><font face="Arial" size="2"><span>I have seen a few
other threads that mention a similar error, however I cant seem to find any
answers on this. Any ideas would be greatly
appreciated.</span></font></div>
<div><font face="Arial" size="2"><span></span></font> </div>
<div><font face="Arial" size="2"><span></span></font> </div>
<div><font face="Arial" size="2"><span>Regards
Matt</span></font></div>
