Understanding the Phone Startup Process Chapter 2 An Overview of the Wireless Network Table 2-5 Cisco IP Phone Startup Process (continued) Step Description Related Topics 4. Configuring IP network If the Cisco Wireless IP Phone is using DHCP to obtain an IP address, the phone queries the DHCP server to obtain one. If you are not using DHCP in your network, you must assign a static IP address to each phone locally. In addition to assigning an IP address, the DHCP server directs the Cisco Wireless IP Phone to a TFTP server. If the phone has a statically defined IP address, you must configure the TFTP server IP address locally on the phone; the phone then contacts the TFTP server directly. • Modifying DHCP Settings, page 5-4 • Configuring Static Settings, page 5-6 • Resolving Startup and Connectivity Problems, page 9-2 5.
