Chapter One: Overview - Cisco SPA504G Manual

Chapter One: Overview

Comprehensive Interoperability and SIP-Based Feature Set
Part of the Cisco Small Business Pro Series, the SIP-based Cisco SPA504G 4-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 SPA504G 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 SPA504G. The Cisco SPA504G 4-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 SPA504G 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.
