Polycom Trio System
The following table lists the individual options and sub-options for DHCP Option 43 supported on the
Polycom Trio system.
Certificate Method Description
Lightweight Directory Access
Protocol (LDAP) Domain
Name System (DNS)
Polycom devices running UC Software 5.3.0 or later that you are registering with
Skype for Business automatically fetch the root certificate using a LDAP DNS
query. Phones you register with Skype for Business are enabled with this feature
by default and no additional configuration is required.
Dynamic Host Configuration
Protocol (DHCP) Option 43
When provisioning phones from within an enterprise, you can use DHCP Option
43 to download a private CA root security certificate used by Skype for Business.
The security certificate is required to support secure HTTPS and TLS
connections.
In conjunction with DHCP Option 43, ensure that your devices can access Skype
for Business Server Certificate Provisioning Web service over HTTP (TCP 80)
and HTTPS (TCP 443).
Note: If you configure DHCP Option 43 in on-premises Skype for Business
deployments, the phone displays only the PIN Authentication menu to users.
For more details and troubleshooting information on DHCP Option 43, see Set Up
DHCP for Devices on Microsoft TechNet.
