Toll-quality voice and carrier-class feature
support: The Cisco SPA112 delivers
clear, high-quality voice communication under a variety of network conditions.
Excellent voice quality in challenging, changeable IP network environments is
made possible through the advanced implementation of standard voice coding
algorithms. The Cisco SPA112 is interoperable with common telephony equipment
such as fax, voicemail, private branch exchanges (PBXs) and key telephone
systems (KTSs), and interactive voice response systems.

Large-scale deployment and management:
The Cisco SPA112 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.

Outstanding security:
The Cisco SPA112 supports highly secure, encryption-based methods for
communication, provisioning, and servicing.

Compact size:
Designed for small spaces, the Cisco SPA112 can be installed as a desktop unit
or mounted on a wall.

Comprehensive feature set:
The standards-based Cisco SPA112 is compatible with Internet VoIP provider
features such as caller ID, call waiting, voicemail, call forwarding,
distinctive ring, and much more to provide a complete, affordable, and highly
reliable solution for high-quality VoIP.

Easy installation and changes:
The web-based configuration utility enables quick deployment and easy changes.
