Wink RE: How do I request a SIP licence (to "downgrade" from SFB firmware)?
Success! I went from:
https://support.yealink.com/en/portal/kn...7c65f78ed5
to:
https://support.yealink.com/faq/faqInfo?id=942
which redirects to:
https://support.yealink.com/en/portal/kn...0471180dd1
and I then followed the instructions on the second half of the page ("Resolution For SFB User"):
I created a new licence on https://license.yealink.com which I downloaded to my PC, I installed that licence on the T41S, rebooted the phone, and I was then able to successfully upgrade (/downgrade?) to the "standard" "SIP Edition" firmware. I did not need to create a ticket at https://ticket.yealink.com/.

Yay!
