Product Overview

The Cisco ® SPA9000 Voice System combines the rich feature set of a high-end private branch exchange (PBX) telephone system with the convenience and cost advantages of voice over IP (VoIP). It has common voice system features such as an automated attendant, shared line appearances, three-way call conferencing, intercom, music on hold, call forwarding, and much more. The SPA9000 opens up access to the benefits of VoIP, including low-cost long-distance service, telephone number portability, and one network for both voice and data.
The Cisco SPA9000 is easy to configure, and a fully working system can be set up in minutes. New telephones are automatically detected and registered when they are connected to the SPA9000. Its integrated web server allows features to be configured using a web browser. The web server has multiple levels of password-protected access to user and service-level features. Service-level settings can be locked by the Internet telephony service provider to ensure that they are not inadvertently corrupted. The service provider also can remotely update the software and settings through a highly secure encrypted connection.
With its integrated router, the Cisco SPA9000 can be connected either directly to the Internet connection or to another router on your network. The SPA9000 has separate WAN and LAN Ethernet ports. The WAN connection can be connected through Dynamic Host Configuration Protocol (DHCP) or a fixed IP address. The LAN port can assign IP addresses to IP telephones and computers using Network Address Translation (NAT) and DHCP.
Although the Cisco SPA9000 will work with any Session Initiation Protocol (SIP) compatible IP telephone, it is the ideal host for Cisco Small Business IP Phones, such as the Cisco SPA901, SPA921, SPA922, SPA941, and SPA942. Powerful configuration capabilities enable the SPA9000 to support a greater set of advanced features with these telephones, such as shared line appearances, hunt groups, call transfer, call parking lot, and group paging. With its two FXS ports, the SPA9000 can support traditional analog devices such as telephones, answering machines, FAX machines, and media adapters. The SPA9000 initially supports 4 SIP-compatible IP phones and is upgradable to 16 IP phones with an easy-to-install license key upgrade.
