DHCP Option 160 and Option 161
Skype for Business phones also support obtaining the provisioning server address by
detecting a DHCP custom option during startup.
If DHCP Option 66 is not available, use a custom option (160 or 161) with the URL or IP
address of the provisioning server. The phone will automatically detect option 160 or 161
for obtaining the provisioning server address.
To use DHCP option 160 or option 161, make sure the DHCP Active feature is enabled
and custom option is configured.
