I have deployed a brand new 7912 with a SIP image (8.0.1(060412A)). The device registered and is able to receive/make calls however the device is intermittently rebooting with no error message. The logs on the phone also contain no information. The phone is powered by PoE, looking at the logs on the switch all I can see is the switchports going down and up again. All patching/cabling is new so I am doubting it is a problem with this, I can also see no errors on the switchports connected to the phone.
Any help would be greatly appreciated.
