Cisco SPA112

The Cisco SPA112 2 Port Phone Adapter enables high-quality, feature-rich VoIP service through a broadband Internet connection. Easy to install and use, the adapter connects to a router or gateway and then provides two independent standard telephone ports to connect analog phones or fax machines to a VoIP service provider for clear voice calls, reliable fax connections, and simultaneous Internet use. The standards-based 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 VoIP solution.

Benefits

Enables high-quality, feature-rich voice over IP (VoIP) service through a broadband Internet connection

Two standard telephone ports, each with an independent phone number, for use with analog phones or fax machines

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 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 via the advanced implementation of standard voice coding algorithms. The SPA112 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 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.

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