[cisco-voip] 7970 Issue - phones constantly restarting/rebooting

Tue May 18 10:01:42 EDT 2010

I guess it’s related to some older firmware bug which will actually crash halfway while loading the latest firmware. The correct way is to flash it to some intermediate release before going for the latest firmware. 

However, the shortest  way you can try out is to do a factory reset and connect it back into the network. (If you don’t have too many phones to factory reset)

Subject: [cisco-voip] 7970 Issue - phones constantly restarting/rebooting

Morning All,

We’ve recently installed a stack of switches and have connected approximately ten IP 7970 phones with 7914 side carts. One other 7970 is without a side cart.

The ports have been setup as access ports with a data and voice vlan. The phones register and function fine. However, all 7970 phones recently installed reboot themselves intermittently and have been doing so for the past 48 hours.

Port config as follows:

switchport access vlan XXX

 switchport mode access

 switchport voice vlan XXX

 spanning-tree portfast

The phones are running firmware SCCP70.8-5-3S. Nothing else appears out of the ordinary and all other phones in our LAN and WAN appear stable. I have included a debug display of one of the phones that keeps rebooting. Any help would be appreciated.
