Stylish and functional in design, the SPA921 VoIP
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 SPA921 leverages industry
leading VoIP technology from Linksys to deliver an upgradeable high quality IP
Phone that is unparalleled in features, value, and support.
Standard features on the SPA921 include a high
resolution graphical display, speakerphone, and a 2.5 mm head-set port. The
SPA921 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.
Comprehensive Interoperability and SIP Based
Feature Set
Based on the SIP standard, the SPA921 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 sevice parameters,
the SPA921 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 of the SPA921.
Carrier-Grade Security, Provisioning, and
Management
The SPA921 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, pre-loading, and re-configuring customer premise equipment
(CPE).
