Had you already configured the phones prior to upgrade? That's my concern. These have been deployed for some time.

I haven't experienced this issue with yealink, but I have with other manufacturers. Hopefully yealink can answer?

Yes I had configured them. The phone settings where maintained throughout the firmware update.

However I always recommend factory resetting before the firmware update and factory resetting immediately after the firmware update as I have known customers to experience issues that this process quite often resolves.

I have seen the same, some issues happen after upgrading a firmware and it resolves after I reset the phone to factory default.
