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).
