If you do not have the ability to configure the DHCP options for discovering the provisioning
server on the DHCP server, an alternate method of automatically discovering the provisioning
server address is required. Connecting to the secondary DHCP server that responds to DHCP
INFORM queries with a requested provisioning server address is one possibility. For more
information, refer to
http://www.ietf.org/rfc/rfc3925.txt?number=3925
The following shows the common options when deploying Yealink Skype for Business phones
with Skype for Business Server. For more information, refer to

DHCP Option 66 and Option 43
Yealink Skype for Business phones support obtaining the provisioning server address by
detecting DHCP options during startup.
The phone will automatically detect the option 66 for obtaining the provisioning server address.
DHCP option 66 is used to identify the TFTP server. DHCP option 43 is a vendor-specific option,
which is used to transfer the vendor-specific information.
The administrator can use vendor class identifier, specified by DHCP option 60, to send the
Skype for Business phone a customized configuration in option 43. Depending on the vendor
class ID it is configured for, the option 43 might have different values. Two vendor class
identifiers are used when deploying with the Skype for Business Server: a VLAN ID request
(vendor class ID: CPE-OCPHONE) and a certificate provisioning service URL request (vendor class
ID: MS-UC-Client). For more information on DHCP option 60, refer to
on page
To use DHCP option 66 and option 43, make sure the DHCP Active feature is enabled.
