Downgrade W56H to 3CX supported version

[IA Alan]

We have 3 Yealink W56H phones that came with firmware version 61.85.0.55 which is obviously later than the latest 3CX version of 61.85.0.35 and I can't find any way to downgrade. I've tried using the normal upgrade method but nothing changes on these devices.

Is there any way to downgrade these for use on 3cx?

Thanks, Alan.

In response to your question, you'll need to reach out to the vendor (Yealink Support) for assistance with achieving this setup.

Always install the version found here if your current is older: https://www.yealink.com/en/solution-detail/resource-for-3cx

If you have an issue, and contacted Yealink, and they recommended a downgrade then go ahead. Else leave it as is.

That's the version I'm trying to get installed but the current version is newer and I can't find any way to downgrade. I've asked Yealink for support just waiting on them.
