We have a customer which is using about 100 Cisco phones (6941). These phones do not use anything else then hunt and pickup groups. The sales department (and a couple of other phone users) are reporting that their phone gets stuck. This means that the 'line'-button light keeps flashing red. The phone does not respond to anything you do. The screen shows the normal idle screen. The PC behind the phone keeps working. The only way to get the phone working again is to replug the network cable.
These people have been working with the phones for about 2 years without problems. We have not changed anything in the configuration (as far as I know..) and now suddenly the problems start occuring. It involves about 15 people / phones who are reporting problems.
We are running CUCM 8.0.3 with the default 6941 firmware (not sure which phone firmware). I tried logging into CUCM to retrieve the phone firmware version but I get the welcome screen and then it doesn't continue loading after I click on "continue to this website...".
