I have a brand new T41s with firmware for testing purposes in our SfB on premise company.
But I cannot register.
Is there any special firmware needed and if so where can I download it?

I generated a license but there is no option to install it via browser.

Settings on the phone are:
SfB2015.contoso.com:5060, tcp

But SfB Server answers at my register-message with:

SIP/2.0 480 Temporarily Unavailable
FROM: "MisterX"<sip:MisterX@contoso.com:5060>;tag=1092311410
TO: "MisterX"<sip:MisterX@contoso.com:5060>;tag=556d7d4845
CALL-ID: 0_3091487279@
VIA: SIP/2.0/TCP;branch=z9hG4bK131413635

Dear customer,

This is Aishion from Yealink technical team, nice to know you. My pleasure to work for you!

Please kindly upgrade to below SFB firmware and test again, please note that the phone need to factory reset after upgrade to SFB version to make the features on the SFB phone work fine. (You can do this step before or after you import a license.)


About how to import license, please kindly refer to below FAQ;


Any question, please feel free to contact us.

Best Regards
