ISR4351-V/K9 Overview
ISR4351-V/K9 Exact Bundle Identity
ISR4351-V/K9 is the Cisco ISR 4351 Unified Communications bundle. The base hardware is the ISR 4351 branch router with three onboard Gigabit Ethernet interfaces, three NIM slots, one ISC slot, two service-module slots, 4 GB flash and 4 GB DRAM.
Bundle and performance boundary
Licensed bundle: V bundle: UC license with a PVDM4-64 voice DSP; security and APP licenses are not implied. Platform performance: 200 Mbps base platform performance, upgradeable to 400 Mbps with the documented performance license. Performance-license values are platform limits, not a promise of application throughput in every configuration.
Voice gateway bill-of-materials check
Verify the PVDM4-64 is physically present and recognized, then separately size analog or digital voice NIMs, CUBE sessions, SRST/CME endpoints and current software subscriptions. The UC bundle does not automatically prove that every voice interface, endpoint entitlement, security package or support contract is included.
Lifecycle and migration
Cisco lists the ISR4351 and this V bundle as end of sale with support ending 30 November 2028. Cisco Catalyst C8200-1N-4T is the published migration product for this ISR4351 generation. Treat the replacement as a migration starting point: interface modules, voice resources, software features, rack power and configuration must be mapped rather than assumed compatible.
