Provisioning Polycom VoIP phones using ISC DHCPD

Using ISC DHCPD's concept of classes, we have a simple and powerful way of provisioning Polycom VoIP phones.

In the main body of the dhcpd.conf file (outside of any subnet declarations), we are going to define a couple custom Polycom options, then define the class, and match statements - which determine when the class is applied to DHCP clients. The class definition is also a good place to include some global options that will be applied to all Polycom clients, regardless of what subnet they end up on.

For the purposes of these examples, we're going to pretend our TFTP server is 10.0.1.2, and we are going to provision our phones to boot up on VLAN42 (10.0.42.0/24).

# Custom options used by Polycom clients
