<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>Judging from your logs it seems more to do with path
changes/vlan changes. What type of switches and phone firmware are you
running?<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>Are they attached to a stack of switches? If so are there
multiple paths in/out or spanning-tree loop that could be directly associated to
your voice vlan?<o:p></o:p></P></DIV>

<P class=MsoNormal><BR>I agree with Stephen,<BR><BR>We see alot of restarts from
DHCP issues, we run DHCP from the router and IP conflict logging is a pain as
you start to run out of IPs real quick so we turn logging off.<BR><BR>The other
issue could be the "Maximum Number of Registered Devices" call manager service
parameter. When we got to over 5000 phones weird things started with phone
reboots and registration. Changed the value to fit our cluster and all is
ok.<BR><BR><BR>On Fri, Feb 18, 2011 at 8:32 AM, Mauro Celli <<A
