| 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). |
