Need to remove custom Fonality firmware

[1CCT]

More info:
In the Baracuda networks they have noted this solution found previously.

We recently encountered a situation with a Barracuda partner using Yealink T42 and T46 phones that had previously been provisioned to Fonality hosted service. These phones refused to downgrade to the phone firmware we use on our phone system GA firmware and also refused to upgrade to the firmware we use on our most recent EA firmware. These phones were on a custom Fonality firmware which showed the following issues:

The web UI for the phones showed a Fonality logo instead of a Yealink logo
The phones showed a Fonality logo on the LCD superimposed over the top of the background image we send to the phones
The BPS does not correctly read DTMF from the phones causing issues with calling auto attendants, checking voicemail, etc.

These phones refused to take a manual upgrade or downgrade off the Fonality firmware via the phones’ web UI as well.

The partner followed up with Yealink and Yealink provided a link to download firmware files that these phones WILL accept for a manual firmware update, after which the phones will then upgrade or downgrade to the firmwares we ship on the BPS. This will resolve the above issues. The download link is:

The larger file is for the T46G and the smaller one is for the T42G.

I wanted to pass this along to our customer base due to the likelihood of someone encountering this again in the future at some point.
