Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G Setup
1 Powering on the phone. The Cisco Unified Wireless IP Phone has nonvolatile flash memory in which it
stores firmware images and user-defined preferences. At startup, the phone runs a bootstrap loader that
loads a phone image stored in Flash memory. Using this image, the phone initializes its software and
hardware.

2 Scanning for an access point. The Cisco Unified Wireless IP Phone scans the RF coverage area with its
radio. The phone searches its network profiles and scans for access points that have a matching SSID and
authentication type. The phone associates with the access point with the highest RSSI that matches with
its network profile.

3 Authenticating with access point. The Cisco Unified Wireless IP Phone begins the authenticating process.
• If set for Open, then any device can authenticate to the access point. For added security, static WEP
• If set to Shared Key, the phone encrypts the challenge text using the WEP key and the access point
• If set for LEAP, EAP-FAST, or PEAP, the username and password are authenticated by the RADIUS
• If set for EAP-TLS, the phone requires one or more of the following certificates:
• If set for Auto (AKM), the phone looks for an access point with one of the following key management
4 Configuring IP network. If the 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 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.
