ISR4331-V/K9 Cisco ISR 4331 Unified Communications Bundle Router

ISR 4331 Unified Communications Bundle

ISR4331-V/K9 is an exact Cisco order on the ISR 4331 with three onboard Gigabit Ethernet interfaces, two NIM slots, one ISC slot and one service-module slot. Bundle boundary: V identifies the unified-communications order; APP and SEC technology-package rights are not implied.

Throughput and workload boundary

100 Mbps default aggregate throughput, upgradeable to 300 Mbps with the documented performance license. Published aggregate throughput is a licensing boundary; encryption, application inspection, voice media and modular services can change measured workload capacity.

Exact procurement checks

Inventory the PVDM, UC entitlement, voice NIMs and any service module. Size codecs, transcoding, conferencing, CUBE/SRST/CME use and call concurrency independently; the V suffix is not an unlimited voice-capacity statement.

Model-specific migration evidence

Use the single service-module position deliberately. Record whether it carries an application module, storage or another supported service and include that dependency in the Catalyst 8300 migration design.

Lifecycle plan

Cisco ended sale for this ISR 4000 generation and identifies 30 November 2028 as the last date of support for the affected platform family. Evaluate the published Catalyst 8200 or 8300 migration family against exact ports, NIM functions, performance, licenses and voice resources; do not assume module or entitlement transfer.

Receiving record

Capture exact PID and serial, memory, flash, power supply, NIM/ISC/service-module inventory, PVDM where applicable, IOS XE release, performance license and active technology-package entitlements. Save configuration and test evidence with the asset.
