set up by the system administrator.) Configuration can be either automatic or manually set up for

phone and move to the new location anywhere on their network. No system administration is

Help
The online help feature gives users information about the phone keys, buttons, and features. The

the Directory button can show local and server-based directory information (Figure 7).

The internal Cisco two-port Ethernet switch allows for a direct connection to a 10/100BASE-T
Ethernet network through an RJ-45 interface with single LAN connectivity for both the phone and a
co-located PC. The system administrator can designate separate VLANs (802.1Q) for the PC and
Cisco IP phones, providing improved security and reliability of voice and data traffic.

speakerphone, handset, headset, and ringer. The handset is hearing aid-compatible (HAC) and
meets FCC loudness requirements for Americans with Disabilities Act (ADA). Section 508
