Cisco 6921 Phone get hangs

[SAURABH KUMAR]

Hi,

I have few Cisco 6921 phone models. In which the phones are getting hanged. The users are not able to press any keys and not able to dial anything. I have done factory reset also but it didnt worked. The only way left is plug in and plug out to make it running. I need some solution on this. Can anyone help me this.
