The line can be configured as a

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

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). |
