Hi Scottie,
This is Walter from Yealink Team. Nice to work with you.

We have made some restrictions on the downgrading of SFB to SIP Phone. You need to import sip license before downgrading. Can you provide the MAC of your phone and your Email address? We will apply for a license for you
Any update, please feel free to let me know.

Best Regards

Still waiting for the e-mail? No love? :-(
