Cisco SIP Support

The Cisco SIP-enabled product portfolio encompasses multiple components of a SIP network infrastructure, from IP phones and access devices to call control and PSTN interworking. Examples of Cisco SIP products include the following:

Cisco IP phones The Cisco IP phone series, including the 7970, 7960, and 7940 Cisco IP phones, support SIP user-agent functionality. These IP phones deliver functionality such as inline-power support and dual-Ethernet ports, and deliver traditional desktop functionality such as call hold, transfer, conferencing, caller ID, call waiting, and a lighted message-waiting indicator.
Cisco ATA 186 Analog Telephone Adaptor The Cisco ATA 186 supports SIP user-agent functionality. With two FXS ports and a single Ethernet port, the ATA 186 provides a low-cost means to connect analog phones to a SIP network. The ATA 186 also delivers traditional desktop functionality such as call hold, transfer, conferencing, caller ID, and lighted call-waiting and message-waiting indicators.
Cisco packet voice gateways The Cisco 1700 modular access routers that are voice capableCisco 2600 Series multiservice platforms, Cisco 3800 Series multiservice platforms, 3700 Series multiservice platforms, Cisco AS5000 universal gateways, and Cisco 7200 Series voice gatewaysall support SIP user-agent functionality. These devices provide a means of connecting SIP networks to traditional time-division multiplexing (TDM) networks via T1, E1, Digital Service 3 (DS3), channel associated signaling (CAS), PRI/BRI, R2 signaling, FXS, Foreign Exchange Office (FXO), or ear-and-mouth (E&M) interfaces. Cisco packet voice gateways are used to build the largest IP telephony networks in the world.

Cisco SIP Proxy Server The Cisco SIP Proxy Server provides the functionality of a SIP proxy, SIP redirect, SIP registrar, and SIP location services server. The Cisco SIP Proxy Server provides the foundation for call routing within SIP networks and can work with traditional SIP location services such as DNS or telephone number mapping (ENUM), with feature servers via a SIP redirect message and with H.323 location services using standard location request (LRQ) messages. The Cisco SIP Proxy Server runs on either Solaris or Linux operating systems.

Cisco BTS 10200 Softswitch The Cisco BTS 10200 provides softswitch functionality to Class 4 and Class 5 networks and provides SIP-to-Signaling System 7 (SIP-to-SS7) gateway functionality for American National Standards Institute (ANSI) standardized networks. The BTS 10200 supports SIP user-agent functionality in conjunction with a Cisco voice media gateway such as a Cisco AS5000 Universal Gateway or a Cisco MGX 8000 Series Voice Gateway.

Cisco PGW 2200 PSTN Gateway The Cisco PGW 2200 provides softswitch functionality for Class 4 networks, as well as Internet offload and SIP-to-SS7 gateway functionality for international networks. The PGW 2200 supports ISDN User Part (ISUP) certification in over 130 countries. The PGW 2200 supports SIP user-agent functionality in conjunction with a Cisco packet voice media gateway such as an AS5000 Universal Gateway or an MGX 8000 Series Voice Gateway.

Cisco PIX and ASA Security Appliances The Cisco PIX and the ASA Security Appliances are SIP-aware networking devices that provide firewall and Network Address Translation (NAT) functionality. Because they are SIP-aware, these appliances are able to dynamically allow SIP signaling to traverse network and addressing boundaries without compromising overall network security. The Cisco PIX and the ASA Security Appliances functioning in this capacity are called application layer gateways (ALGs).
