Chapter 6 Understanding the VoIP Wireless Network

Security for Voice Communications in WLANs

The Cisco Unified IP Phone does not support auto EAP negotiation; to use EAP-FAST mode, you must specify it.

Table 6-4provides a list of authentication and encryption schemes that are configured on the Cisco Aironet APs that the Cisco Unified IP Phone supports. The table shows the network configuration option for the phone that corresponds to the AP configuration.
