You want to use the DHCP server in the existing IP network to address the IP system phones. To do so, add the manufacturer-specific options 60 and 43 to the DHCP server via its configuration interface.
The broadcast address request of an IP system phone comprises the MAC address as well as the vendor class identifier. If the DHCP server finds an assignment for the identifier in its configuration, it is able to provide the IP system phone with the vendor-specific information (Option 43).
