Thank you in advanced

Dear customer,

​This is Aishion from Yealink technical team, nice to know you. My pleasure to work for you! 
I was told that both models come with SIP License. 

How can we activate the SfB license ?


If you are using Skype for business for your phones, yes, you can active SFB license.

We have both SIP and SFB firmware for T46S and T46G, but SIP firmware don't need license.

About how to get SFB license, please kindly refer to below FAQ:


Is there any difference between T46S and T46G?
Yes, the T46G and T46S with difference firmware, and T46S support more features such as Opus codec, firmware unified for T4S series phone.

If any question, please feel free to contact us.

Best Regards
