Question about SfB Licenses

[Renke]

Hello Evan,

thank you !
I hope I got it:
When I bought a Yealink phone with SfB license included, the license always is a permanent one.
The license is not shipped together with the phone.
It has to be obtained from your company by request.
Obtaining the permanent license may take some time, so the 90 days license is for intermediate use and testing.
Can I say it like this ?

Best Regards

Renke
