Product Overview

The Cisco ® Unified IP Phone 500 Series is a new group of affordable, entry-level IP phones designed for use with Cisco's Unified Communications 500 Series for Small Business. These phones are an excellent choice for customers making the transition from traditional digital or hybrid key systems (KTS) and private branch exchanges (PBXs) to a system based on the Cisco Unified Communications 500 Series. The Cisco Unified IP Phone 500 Series can easily be integrated into the Cisco Smart Business Communications System. They can be used in cubicles, retail settings, classrooms, breakrooms, lobbies, and manufacturing areas. The phones are optimized to replace traditional voice systems or transition to a next-generation voice solution in a Category 5 (CAT5) wired environment. The 521SG and 524SG phones offer customers the additional option of having a 10/100 switch port for LAN connection to a co-located PC. For customers with no need for a co-located PC, the 521G and 524G models can be used.

Figure 1. Cisco IP Phones 500 Series

The Cisco Unified IP Phones 521G and 521SG are single-line IP phones with two call line appearances. The Cisco Unified IP Phones 524G and 524SG are four-line IP phones with up to eight call line appearances. Four dynamic soft keys on each phone guide you through core business features and functions, while a backlit pixel-based display combines intuitive features, calling information, and device system information to give you information at your fingertips. The Cisco Unified IP Phones 521G, 521SG, 524G, and 524SG can be powered by a network switch with Power over Ethernet (PoE) capability or by an optional power adapter. The phones are in line with Cisco Green, incorporating power efficiency features such as LCD shutoff to save power when the phone is not in use. These phones can also be used with productivity-enhancing features such as directory search and VoiceView Express.

Features

The Cisco Unified IP Phone 500 Series can easily grow with your business. The phones are capable of having new feature functionality added over time via firmware updates. Plus, if you hire an employee or an employee needs to move locations, they can simply plug in their preconfigured phones anywhere on the network, and the network will recognize the change. The phones also provide accessibility features for those with special needs.
