Chapter 1 An Overview of the Cisco Unified IP Phone What Features are Supported on the Cisco Unified IP Phones 7960G and 7940G? Table 1-1 Supported Networking Protocols on the Cisco Unified IP Phone (continued) Networking Protocol Purpose Usage Notes Skinny Client Control Protocol (SCCP) SCCP includes a messaging set that allows communications between call control servers and endpoint clients such as IP Phones. SCCP is proprietary to Cisco Systems. Cisco Unified IP Phones use SCCP for call control. You can configure the Cisco Unified IP Phone to use either SCCP or Session Initiation Protocol (SIP). Transmission Control Protocol (TCP) TCP is a connection-oriented transport protocol. Cisco Unified IP Phones use TCP to connect to Cisco Unified Communications Manager and to access XML services. Transport Layer Security (TLS) TLS is a standard protocol for securing and authenticating communications. When security is implemented, Cisco Unified IP Phones use the TLS protocol when securely registering with Cisco Unified Communications Manager and when communicating with the Certificate Authority Proxy Function (CAPF). 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 specific to the phone type. TFTP requires a TFTP server in your network, which can be automatically identified from the DHCP server. If you want a phone to use a TFTP server other than the one specified by the DHCP server, you must manually assign the IP address of the TFTP server using the Network Configuration menu on the phone.= User Datagram Protocol UDP is a connectionless messaging protocol for Cisco Unified IP Phones transmit and receive (UDP) delivery of data packets. RTP streams, which utilize UDP.
