The Cisco Unified IP Phone family provides industry-leading levels of integrated business functionality and converged communications features beyond today's conventional voice systems—surpassing competitive offerings. Cisco Systems continues to deliver one of the industry's best end-to-end data and true voice over IP (VoIP) solutions, offering the most complete, stylish, and feature-rich IP phones to enterprise and small to midsize customers.

The Cisco Unified IP Phone Expansion Module 7915 extends the capabilities with additional buttons and an LCD display. With this expansion module, you add 12 physical keys with access to 12 additional keys through the page keys for a total of 24 buttons to the existing buttons. You can use up to two Cisco Unified IP Phone Expansion Module 7915 modules with the Cisco Unified IP Phone select models.

Cisco Catalyst 4500-X Series provides scalable, fixed-campus aggregation solutions in space-constrained environments. The solution provides flexibility to build desired port density through two versions of base switches along with optional network module, providing line-rate 10GE capability. Both the 32-port and 16-port versions can be configured with optional network modules and offer similar features. The Small Form-Factor Pluggable Plus (SFP+) interface supports both 10 Gigabit Ethernet and 1 Gigabit Ethernet ports, allowing customers to use their investment in 1 Gigabit Ethernet SFP and upgrade to 10 Gigabit Ethernet when business demands change, without having to do a comprehensive upgrade of the existing deployment. The uplink module is hot swappable.

Cisco is the worldwide leader in networking that transforms how people connect, communicate, and collaborate. Their technology is changing the nature of work and the way we live. Founded in 1984, Cisco pioneered the development of Internet Protocol (IP)-based networking technologies. This tradition continues with the development of routing, switching, and other technologies such as application networking services, home networking, security, storage area networking, TelePresence systems, unified communications, video systems, and wireless.

The Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) enables Cisco 2900 and 3900 Series Integrated Services Routers Generation 2 to provide rich-media capabilities such as high-density voice video connectivity, conferencing, transcoding, transrating, and secure voice in Cisco Unified Communications Solutions. The next-generation high-density packet voice digital signal processor (DSP) modules are available in six densities: PVDM3-16, PVDM3-32, PVDM3-64, PVDM3-128, PVDM3-192, and PVDM3-256, with 16, 32, 64, 128, 192, and 256 channels, respectively.
