[cisco-voip] 7911 factory default reset

[Victor Rodriguez]

I recommend you upgrade the firmware for you 7911 IPphone and then to this procedure (you must use a AC adaptor)

Power off the phone. 

Hold down the # key. 

While holding #, connect an AC adaptor to the phone. 

Continue to hold # until the line buttons blink amber. 

Release the # key. 

Enter 3491672850*# 

The lights should change color from amber to red. When this occurs, the phone is resetting to factory defaults.

Can your phone talk to the tftp server properly?
