Benefits:
Enables high-quality feature-rich voice over IP (VoIP) service
through your broadband Internet connection
Two standard telephone ports for use with analog phones or fax
machines, with independent phone numbers
High-quality,
clear-sounding voice, using advanced voice quality of service (QoS)
capability
Compatible
with all common telephone features, such as caller ID, call waiting, and
voicemail
Ideal solution for residential, home office, and small business
environments
Features:
Toll-quality voice and
carrier-grade feature support: The Cisco SPA122 delivers clear,
high-quality voice communication under a variety of network conditions.
Excellent voice quality in challenging, changeable IP network environments is
made possible via the advanced implementation of standard voice coding
algorithms. The SPA122 is interoperable with common telephony equipment such
as fax, voicemail, private branch exchange (PBX)/key telephone system (KTS),
and interactive voice response systems.
Large-scale
deployment and management: The Cisco SPA122 enables service providers to
provide customized services to their subscribers. It can be remotely
provisioned and supports dynamic, in-service software upgrades. A highly
secure profile upload saves providers the time and expense of managing and
preconfiguring or reconfiguring customer premises equipment (CPE) for
deployment.
Ironclad security: The
Cisco SPA122 supports highly secure, encryption-based methods for
communication, provisioning, and servicing.
*Note: Many specifications are programmable within a
defined range or list of options. Please see the SPA100 Series Administration
Guide for details. The configuration profile is uploaded to the SPA122 at the
time of provisioning.
