Question about SfB Licenses

[Evan_Yealink]

Dear Renke,

I am so sorry that my description of SFB license was unclear.

By default, the Skype for Business phone has a built-in Skype for Business feature license(permanent), which allows user to use Yealink phones with Skype for Business features directly.

If users purchase SIP phones which aren’t running Skype for Business firmware,
while the user wants to upgrade firmware to a Skype for Business firmware, then a Skype for Business feature license is needed to be uploaded to the Skype for Business phone after the update. So you should get the license from our company by request.

About license Expiry Date:
1.when you need to do something testing with the Lync/SfB functionality, you can submit your application of 90 day licenses, that make faster using and testing.
2.when you confirm use the Phones of SFB firmware, you can submit the permanent license for use.

By the way, how many phones you want ? When testing? When deploying?
Would you mind sending the project information to my E-mail ? evan@yealink.com

Any question, freely to let me know.

Best Regards,
Evan You
