CH A P T E R 1 Cisco ATA 190 Analog Telephone Adapter Overview This section describes the hardware and software features of the Cisco ATA 190 Analog Telephone Adapter (ATA 190) and includes a brief overview of the Session Initiation Protocol (SIP). The ATA 190 analog telephone adapters are handset-to-Ethernet adapters that allow regular analog phones to operate on IP-based telephony networks. The ATA 190 supports two voice ports, each with an independent phone number.
Chapter 1 Cisco ATA 190 Analog Telephone Adapter Overview Session Initiation Protocol Overview Session Initiation Protocol Overview Session Initiation Protocol (SIP) is the Internet Engineering Task Force (IETF) standard for real-time calls and conferencing over Internet Protocol (IP). SIP is an ASCII-based, application-layer control protocol (defined in RFC3261) that can be used to establish, maintain, and terminate multimedia sessions or calls between two or more endpoints.
Chapter 1 Cisco ATA 190 Analog Telephone Adapter Overview Session Initiation Protocol Overview • User agent server (UAS)—A server application that contacts the user when a SIP request is received and returns a response on behalf of the user. Typically, a SIP endpoint is capable of functioning as both a UAC and a UAS, but functions only as one or the other per transaction. Whether the endpoint functions as a UAC or a UAS depends on the UA that initiated the request.
Chapter 1 Cisco ATA 190 Analog Telephone Adapter Overview Hardware Overview • Proxy server—The proxy server is an intermediate device that receives SIP requests from a client and then forwards the requests on the client’s behalf. Proxy servers receive SIP messages and forward them to the next SIP server in the network. Proxy servers can provide functions such as authentication, authorization, network access control, routing, reliable request retransmission, and security.
