Cisco IP Telephones plug into Ethernet ports. LAN servers provide the majority of the features that formally the Public Branch Exchange (PBX) provided. An IP telephone's speaker and a microphone are plugged into the PC. There are both hardware and software IP phones. Hardware IP phones need a jack on the switch and its own power supply. Some switches, like the Cisco Catalyst 6500 can provide power. A basic IP telephone call occurs when one IP telephone connects to another. IP telephones' functions are performed by IP telephony servers. Under the H.323 protocol, this set of functions (such as voice messaging and voice conferencing) is performed by a gatekeeper.
