Configuring DHCP to work with Cisco Manager

This Tech-Recipe describes using an external DHCP server, in this case from a Windows Server 2000 or 2003 system, with Cisco Call Manager (CCM). When introducing CCM into environments with an exsiting DHCP infrastructure, problems may occur because Cisco IP phones require additional information from the DHCP server when they startup. Following the steps in this Tech-Recipe will allow the use of a non-CCM DHCP server.
