speakerphones, and fax machines, as well as control their migration to IP with an extremely affordable, reliable solution.

Installed by the end user and remotely provisioned, configured, and maintained by the service provider, each Cisco SPA2102 converts voice traffic into data packets for transmission over an IP network. Compact in design, the SPA2102 can be used in consumer and business VoIP service offerings, including full-featured IP Centrex environments. The SPA2102 uses international standards for voice and data networking for reliable operation.

Features

●Toll-quality voice and carrier-grade feature support: The Cisco SPA2102 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 SPA2102 is interoperable with common telephony equipment such as fax, voicemail, PBX/KTS, and interactive voice response systems.

●Large-scale deployment and management: The Cisco SPA2102 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 SPA2102 supports highly secure, encryption-based methods for communication, provisioning, and servicing.
