Linksys FACTORY UNLOCK SPA 9000 SPA9000

Setting up the internal telephone system for a small business was once strictly the domain of the phone company. Now, you can not only do it with a cost-conscious voice over IP (VoIP) connection, but it's also so simple just about anyone can set up a fully working system in minutes. Formerly part of the Linksys Voice System (LVS), now part of Cisco Small Business Voice Systems, the SPA9000 Voice System combines all the features of a traditional phone system—automated attendant functions, three-way conferencing, intercom, hold music, call forwarding, and more—with low-cost long-distance service and a single network for both voice and data. Additional features of the Cisco SPA9000 Voice System include: High-end features comparable to voice services traditionally found in large businesses Support up to 16  IP phones Multiple levels of password-protected access The ability for an Internet telephone service provider to remotely update software and settings Support for advanced features like shared line appearances, hunt groups, call transfer, call parking, and group paging Specification: Voice Codec: G.711 G.726 G.729a G.723.1 G.165 Interfaces/Ports: 1 x RJ-45 10/100Base-TX LAN 1 x RJ-45 10/100Base-TX WAN 2 x RJ-11 FXS Connectivity Media: Twisted Pair 10/100Base-TX Data Transfer Rate: 10Mbps Ethernet 100Mbps Fast Ethernet Management: Syslog VLAN Tagging - 802.1p/q QoS - Voice Packet Prioritization over Other Packet Types Web Browser Administration & Configuration via Integral Web Server Security Features: Password Protected System Reset to Factory Default Password Protected Admin and User Access Authority HTTPS with Factory Installed Client Certificate HTTP Digest - Encrypted Authentication via MD5 (RFC 1321) Up to 256-bit AES Encryption Input Voltage: 5 V DC Device 100 V AC to 240 V AC Power Supply Dimensions: 10.11cm Height x 10.11cm Width x 2.79cm Depth Weight: 150.25 g Package Contents: Linksys SPA9000 VoIP Gateway 1 x 5 Volt Power Adapter 1 x RJ45 Ethernet Cable 1 x Quick Installation Additional Information: SIP Application Server, Proxy, Registrar and Location Server (RFC3261) Multiple Service Provider Lines / SIP Account Support (4) Shared Line Appearance (SLA) Support for 16 IP phones Automated Attendant (AA) Configurable AA Answer Delay Voice Mail Integration Interactive Voice Response (IVR) Recordable IVR Prompts Automatic Call Distribution (ACD) Configurable Call Routing Phone Configuration and Management Server Corporate Directory with Automatic Update Music / Information via Streaming Audio Server Integrated Media Proxy or Direct RTP Routing to ITSP Differentiated Services (DiffServ) / Type of Service (TOS) Support Initial support of 16 SIP compatible IP Phones per SPA9000 SIP compatible IP telephone: SPA901, SPA921, SPA922, SPA941, and SPA942
