T48G with SfB Firmware can't Signing in
I have updated my YEALINK T48G with latest Skype for Business Firmware ( and valid license key. The device is configured to get DHCP Option 120.

I use following Login Information on Account/Register page

Login address = <username>@Domain.com
Register Name = <username>@Domain.com
+ Password

After singning in on the Website, I receive following message

Register Failed

the root Certificate from internal CA (Security/Trusted Certificate) have been uploaded to the device

Question: as my DHCP Server have been configured with DHCP Option from Lync Common Area Phones.

Can YEALINK use the same DHCP Option 120 as for Lync Common Area Phones ?

any experience from the field ?
