I have a dozen 7906 Model IP Phones on a CME 4.1 system (12.4(15T)) that used to work fine, and now are not working. All the phones get power, and just cycle with the cisco logo. They are getting a IP Address from the routers DHCP pool which has option 150 set right, etc. I can see this by looking at the show dhcp command on router that the phones have got a new IP address from this pool.
On the IP Phones, they are not getting far enough to get a menu, etc. On power on, the first time through you see the Cisco logo with a square and checkbox in it. Then it sits for a second or so, then just cycles through with another cisco logo and this time a circle with a square/diamond in it, then just keeps repeating that over and over.
I can't seem to break into a menu on the phone at any point by pressing keys, etc as it doesn't seem to be getting that far along.
On the router, if I turn on tftp debugs, I see a request for term06.default every now and then but I'm not sure what device is requesting this because the debugs do not say what IP/mac is doing request.
Is there a way to factory default the phone, or some way to get the phones to start working? Or do I just RMA all 15 phones (hard to believe all of them just went bad).
