we have IP phones at remote place from CCM cluster connected over IP WAN. These phones get automatically rebooted atleast once in a day. Network team searched for the error logs on WAN link and on switches & all devices on the path but no logs found. On CCM, no other error than transient connection is found. Any other possibility?
Check the Switch they are on first to make sure you are not getting some kind of Power problem before you go and trace out the whole network for keep alives, etc. If it's a simple POE problem with the switch, that is the problem.
Turn on SNMP on the switch they are plugged into and log the traps. If it is a POE issue, you should see either the switch rebooting or POE messages, etc.
If the phones have power bricks, then it might be different. bricks will not typically cause hard reboots of IP phones.
