Recently, I have intsalled a new IOS on a cisco router. It was cm2800nm-advipservicesk9-mz.124-22.YB.bin and now is advipservicesk9-mz.124-24.T.bin
After some time I have noticed what all new phones are not able to load a firmware. If I resert old phone it is now loading a firmware as well.
I know what for IP phone 7940 I should use next files:
I checked flash area and found all of them.
After upgrading I see a screen with a cisco logo and nothing happens after that.
And it is also looked like phone is trying to upload a firmware from wrong tftp server.
Any help how to fix it would be appreciated.
