I have a cisco 7942 phone in which the call history is not getting stored and not showing time.
We have tried rebooting (not factory Reboot) the phone but the issue still persists.
I have checked the CSS and partition with the user having working phone but found nothing.
Please advise what steps can be taken to troubleshoot this issue.
Thanks in advance.
At the release notes there is no bug about this:
You can try the factory reset, however, this method resets all of the settings directly, and the IP Phone will download the firmware that is on the device defaults of the CUCM.
Or you can try to upgrade the firmware individually for this IP Phone:
You can try one of these options, if you have a second phone of backup i advise you try the factory reset. If the factory reset did not work you can try the firmware upgrade
1.Have you checked that it is getting voice vlan IP ?
2.Please check the "CDP Enable" at Switch Port
3.Try to upgrade/downgrade the Firmware.
