ISR4331-VSEC/K9 Use Case

Secure Multi-Branch Voice and Data Convergence with Cisco ISR 4331

A global retail enterprise deploys the Cisco ISR4331-VSEC/K9 bundle with UC & Security License, PVDM4-32 and CUBE-10 at 50 branch sites to establish a DMVPN mesh protected by AES-256 IPsec. The integrated UC platform and embedded Cisco Unified Border Element (CUBE-10) enable secure SIP trunk breakouts, high-quality voice/video, and centralized policy enforcement. Outcome: 60% faster site provisioning, end-to-end encryption, consistent QoS and a 30% reduction in overall WAN costs.

High-Capacity Contact Center Voice Gateway with PVDM4-32 DSP Resources

A financial services firm equips its regional call center with the Cisco ISR4331-VSEC/K9 bundle, leveraging PVDM4-32 DSP modules for voice compression, transcoding and conferencing. The built-in UC license supports IP phones and video endpoints, while CUBE-10 secures SIP sessions with carriers. Outcome: Supports 200 concurrent calls with <10 ms latency, 25% bandwidth savings via G.729 compression, and unified management of voice and security policies.

SIP Trunk Migration and Cloud UC Integration Using CUBE-10

A mid-market manufacturer migrates from legacy T1 circuits to SIP trunks and a hosted UC platform by deploying Cisco ISR4331-VSEC/K9 with UC & Security License and CUBE-10. The solution provides secure SIP session border control, call routing, and PSTN breakout, while PVDM4-32 ensures flawless media interworking. Outcome: Eliminates PRI costs, accelerates cloud UC adoption by 50%, and delivers unified voice, video and collaboration with service-level consistency.
