Advanced, Affordable, Feature-Rich IP
Phone for Business or a Home Office
Stylish and functional in design, the SPA922 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 SPA922 leverages industry-leading VoIP technology from Linksys to
deliver an upgradeable high-quality IP Phone that is unparalleled in features, value,
and support.
SPA922
Based on the SIP standard, the SPA922 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 SPA922 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 SPA922 include 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. The SPA922 supports one line with two call appearances and
provides support for three-way conferencing, attended call transfer, and placing a call on
hold to answer an incoming call. The line can be configured as a unique phone number (or
extension), or can be configured to share a number that is assigned to multiple phones.
The SPA922 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).
*The power supply for the SPA922 is sold separately and is required if PoE functionality is not implemented.
