Comprehensive Interoperability and SIP-Based Feature Set
Part of the Cisco Small Business Pro Series, the SIP-based Cisco SPA508G 8-Line IP Phone (Figure 1) has been
tested to ensure comprehensive interoperability with equipment from voice over IP (VoIP) infrastructure leaders,
enabling service providers to quickly roll out competitive, feature-rich services to their customers.
With hundreds of features and configurable service parameters, the Cisco SPA508G addresses the requirements of
traditional business users while building on the advantages of IP telephony. Features such as easy station moves
and shared line appearances (across local and geographically dispersed locations) are just some of the many
advantages of the SPA508G.
The Cisco SPA508G 8-Line IP Phone also supports productivity-enhancing features such as VoiceView Express,
and Cisco XML applications when used with the Cisco Unified Communications 500 Series in SPCP mode.
Carrier-Grade Security, Provisioning, and Management
The Cisco SPA508G uses standard encryption protocols to perform highly secure remote provisioning and
unobtrusive in-service software upgrades. Remote provisioning tools include detailed performance measurement
and troubleshooting features, enabling network providers to deliver high-quality support to their subscribers. Remote
provisioning also saves service providers the time and expense of managing, preloading, and reconfiguring
customer premises equipment.
