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.
