Table 1-1 Supported Networking Protocols on the Cisco Unified IP Phone (continued) Networking Protocol Transmission Control Protocol (TCP) Purpose TCP acts as a connection-oriented transport protocol. Trivial File Transfer Protocol (TFTP) TFTP allows you to transfer files over the network. On the Cisco Unified IP Phone, TFTP enables you to obtain a configuration file that is specific to the phone type. User Datagram Protocol UDP acts as a connectionless (UDP) messaging protocol for delivery of data packets. Usage Notes Cisco Unified IP Phones use TCP to connect to Cisco Unified CallManager and to access XML services. TFTP requires a TFTP server in your network, which can be automatically identified from the DHCP server. If more than one TFTP server is running in your network, you must manually assign a TFTP server to each phone locally. Cisco Unified IP Phones receive and process UDP messages.
