Cisco Unified IP Phone 7905G - Repair Only

The Cisco Unified IP Phone 7905G (Figure 1) is a cost-effective, basic IP phone providing a core set of business features. It is specifically suited for enterprise and service provider applications and can be deployed in the following end-user environments: enterprises, small and medium-sized businesses (SMBs), and small offices or home offices (SOHOs). It is also suitable for places where single-line phones are typically installed such as cafeterias, break rooms, lobbies, and manufacturing floors.

The Cisco Unified IP Phone 7905G provides single-line access and four interactive soft keys that guide a user through call features and functions on the pixel-based liquid crystal display (LCD). The graphic capabilities of the display support a rich user experience, presenting calling information, intuitive access to features, and language localization in future firmware releases.

The Cisco Unified IP Phone 7905G supports inline power, which allows the phone to receive power over the LAN. This capability gives the network administrator centralized power control, which translates into greater network availability. In addition, Extensible Markup Language (XML) applications deliver impressive features and network data to the Cisco Unified IP Phone 7905G display.
