DHCP Option 160 and Option 161
Yealink Skype for Business phones also support obtaining the provisioning server address by
detecting DHCP custom option during startup.
If DHCP Option 66 is not available, you can use custom option (160 or 161) with the URL or IP
address of the provisioning server. The phone will automatically detect the option 160 or 161 for

To use DHCP option 160 or option 161, make sure the DHCP Active feature is enabled and
