Question about SfB Licenses

[Evan_Yealink]

Dear，

For your question:

1.Generally, we are not pre-configured the license on the phone, you can get license from our official website, as below link:
http://sfblicense.yealink.com/license
For more information, please kindly refer to the FAQ:
http://support.yealink.com/faq/faqInfo?id=380

If you have specific project requirement, we can build-in the license on the SFB phone, please kindly send the detail information to my E-mail: evan@yealink.com

2.By the way, if the SFB license is imported into the phone, the SFB license will not be voided before Expiry Date. That is, upgrade from SFB to SIP firmware, then upgrade to SFB firmware, you don’t need to import license again.

Let me know if any question.

Best Regards,
Evan You
