7911 registering issue

Since a couple of days one of our Cisco 7911 IP phones doesn't work anymore.

It just keeps showing "Registering" on the display.

In the Cisco UCM Administration the status is "Unregistered".

How can I register this phone?

Could a factory reset help?

Thanks for your help.

7911 registering issue

To be honest  , you don't really give enought information to go on , however try these.

1.Have you checked the config on switchport hasn't changed , i.e the phone is not in correct vlan

2.Is this the only phone having an issue .i.e it could be faulty.

3.Have you ruled out the cabling? i.e do you know its not a cable fault.

4.Have you done any upgrades recently  to callmanager of firmware? is it related?

5.Have you powered off the phone and back on to see if that works?

cheers
