Linksys SPA942 Summary

Linksys SPA942 - Four Line IP Phone

This phone does not come with a power supply in the box. Please add it above if you are not using a PoE Switch!

Advanced, Feature-Rich, Multi-Line IP Phone for Business or a Home Office

Comprehensive Interoperability and SIP Based Feature Set

Stylish and functional in design, the SPA942 IP Phone is ideal for a residence or business using a hosted IP telephony service, an IP PBX, or a large scale IP Centrex deployment. The SPA942 leverages industry-leading VoIP technology from Linksys to deliver an upgradeable high-quality IP Phone that is unparalleled in features, value, and support.

Based on the SIP standard, the SPA942 has been tested to ensure comprehensive interoperability with equipment from VoIP infrastructure leaders, enabling service providers to quickly roll out competitive, feature-rich services to their customers.

With hundreds of features and configurable service parameters, the SPA942 addresses the requirements of traditional business users while leveraging the advantages of IP telephony. Features such as easy station moves, presence, and shared line appearances (across local and geographically-dispersed locations) are just some of the many advantages.

Standard features on the SPA942 include two active lines, dual-switched Ethernet ports, 802.3af Power Over Ethernet (PoE)* support, a high-resolution graphical display, full-duplex speakerphone, and a 2.5 mm headset port. With a simple software update, the SPA942 is upgradeable to a four-line phone. Each line can be independently configured to use a unique phone number (or extension), or can be configured to use a shared number that is assigned to multiple phones.

The SPA942 uses standard encryption protocols to provide secure remote provisioning and unobtrusive in-service software upgrades. Linksys secure remote provisioning tools include detailed performance measurement and troubleshooting features, enabling network providers to deliver high-quality support to their subscribers. Remote provisioning also saves service providers the hassle and expense of managing, preloading, and re-configuring customer premise equipment (CPE).
