Future End-of-Sale announcements for these products will be posted at:

The End-of-Sale announcements for Cisco 1811 and 1812 routers have been announced and can be found at:

Q. What is the reason for the End-of-Life announcement?
A. Integrated Services Router 1841, 2800, and 3800 Series product families have lead the access routing market for the past 6 years; however with greater demands in the branch for higher performance for next-generation WAN connectivity, increased media collaboration, video and virtualization applications, Services on Demand, and greater improvements in energy savings, a new generation of Integrated Services Routers platforms are required.

Built on 25 years of innovation and product leadership along with broad market acceptance, the Integrated Service Routers Generation 2 continues to optimize service integration to transform the branch office experience with the speed, scale, and flexibility to deliver tomorrow's services transparently at a low cost of ownership.

Q. What are the recommended migration paths for Cisco 1800, 2800, and 3800 Series?
A. It is recommended that customers migrate to the Integrated Service Routers Generation 2 (ISR G2) 1900, 2900, and 3900 Series. The ISR G2's offer from 3x to 8x performance improvements over the current generation. The ISR G2 platforms are architected to enable the next phase of branch-office evolution, providing rich media collaboration and virtualization to the branch while maximizing operational cost savings. The new Integrated Services Routers Generation 2 are future-enabled with support for new high capacity DSPs (Digital Signal Processors) for future enhanced video capabilities, high powered service modules with improved availability, multi-core CPUs, Gigabit Ethernet switching with enhanced POE, and new energy visibility and control capabilities while enhancing overall system performance.

Additionally, a new Cisco IOS® Software Universal image and Services Ready Engine module enable you to decouple the deployment of hardware and software, providing a flexible technology foundation which can quickly adapt to evolving network requirements. Overall, the Cisco 3900 Series offer unparalleled total cost of ownership savings and network agility through the intelligent integration of market leading security, unified communications, wireless, and application services.

The Cisco 2900 and 3900 Series Integrated Services Routers extend this leadership in total cost of ownership by offering Services on Demand, reducing initial capital outlays by decoupling the delivery of software from hardware on optional service modules. In addition, customers receive a Universal IOS image, capable of enabling all of Cisco's rich IOS features allowing you to quickly deploy new services without having to download a new IOS image.

The Cisco 1900, 2900 and 3900 architecture has been designed with higher efficiency power supplies that provide energy-savings features that include intelligent power management, allowing customers to control power to a specific module based on time of day, with full Cisco Energy Wise feature support in the future. The 3945E, 3925E, 3945 and 3925 routers exclusively support dual power supplies with AC, DC or POE options. This enables power supply redundancy for branch or retail environments running mission critical applications.

Overall, the Cisco ISR G2 Series offers unparalleled operational savings and network agility through the continued intelligent integration of market leading security, unified communications, wireless, and application optimization services.

The recommended product migration path for base chassis and bundles is captured in the 1841, 2800 and 3800 End-of-Life and End of Sale Notices located at:

Q. What are some of the key reasons customers choose to migrate from the ISR G1 to ISR G2 platforms today?
A. Key elements driving the migration to the ISR G2's today are:

Video in the Network: Designed to deliver video to remote locations - enable video streaming, conferencing, transcoding, trans-rating using PVDM3 DSPs

Services On-Demand: Offers a flexible model to deploy applications in the branch without a separate truck-roll, decoupling purchase cycles for router and Services Ready Engine (SRE) module from the application

Migration to Ethernet WAN: ISR G2s offer 3-8x higher performance than previous generation ISR platforms and the broadest range of WAN options

Increasing scale of UC deployments: ISR G2 roughly double the scale of CME and SRST support up to 450 and 1,500 phones & up to 24 T1/E1s for voice gateway functions

Optimizing WAN usage: With WAAS on SRE or Wide-Area Application Services (WAAS) Express, enhancing application performance and richer-media experience in remote locations with low-speed links

SIP Trunking: ISR G2 routers with CUBE features act as Session Border Controllers to allow customers to migrate from TDM to SIP trunking environments, scaling up to 2,500 SIP sessions

Securing the Branch: Delivers most comprehensive architectures for VPN deployment between sites along with Stateful Firewall and UTM capabilities for remote locations

Q. What are some of the key business drivers for migration at the Branch office?
A. Some of the key business drivers are:

• Geographical expansion/consolidation including mergers or reorganization

• Regulatory compliance-PCI, HIPPA, SOX, physical security, etc

• New business models-innovative service, production process, QA projects

• Increased employee productivity initiatives, cost savings

• Training, distance learning or e-learning projects

• Green initiatives to reduce energy use and promote sustainability

Q. What are some of the key technical drivers for migration at the Branch office?
A. Some of the key technical drivers are:

• Current and near future End of Software and hardware support for Cisco 1600, 1700, 2600, 3600, 3700 Series routers

• Planned deployment of video & rich-media collaboration in the Branch
