SPA921

IP Phone

Model No.

Advanced, Affordable, 
Feature Rich IP Phone for the 
Home Office and Business

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).
