Cisco 3800 Series Integrated Services Routers: End-of-Life Overview

The Cisco 3800 Series Integrated Services Routers, now end-of-sale and end-of-life, were designed for medium to large-sized businesses and enterprise branch offices. These routers provided a robust, flexible platform to streamline deployment and management while reducing operational costs and supporting scalable network architectures.

Built to support mission-critical applications, the 3800 Series delivered highly secure, concurrent services at T3/E3 wire-speed—including data, security, voice, video, and wireless. With support for up to 2,500 VPN tunnels and up to 720 Cisco IP phone users, these routers offered powerful performance and high service density in a single, integrated solution.

Although retired, the Cisco 3800 Series played a vital role in enabling secure, high-performance branch connectivity for enterprise networks.
