I uploaded the 8.0.0 firmware files to my demo and office UC520 last week. I didn't have any issues as far as upgrading was concerned, but noticed since the firmware upgrade that most of my ringtones sound like a bad internet stream whenever the phone rings. The audio is broken up just enough to be noticible.
Anyone else having these issues?
If more then one phone sounds not good, the audio files maybe corrupted.
You can drag/drop individual phone ring files via CCA, i would download the software pack again, or from earlier SW pack, unpack on your PC, then grap the audio files and drag/drop to CCA. Then reload the phones, hard reboot, and see what happens....
