C2821-VSEC-SRST/K9 Use Case
Branch Office Secure Voice & Data Survivability with C2821-VSEC-SRST Bundle
A retail chain deploys the C2821-VSEC-SRST/K9 bundle at 150 remote outlets to secure VoIP and data over MPLS. Advanced IP Services enable AES-256 encrypted VPN tunnels back to headquarters, while PVDM2-32 DSP resources power up to 50 concurrent calls. FL-SRST-50 provides local call continuity during WAN outages. Outcome: branch offices maintain secure, high-quality voice and critical application access 100% of the time, reducing downtime costs by 75% and ensuring PCI DSS compliance.
Multi-Site Enterprise IP Telephony Gateway with High-Performance Encryption
A financial services firm integrates the C2821-VSEC-SRST/K9 across three data centers to centralize SIP trunking and mitigate fraud. The router’s VSEC license enforces H.235 and TLS encryption for thousands of simultaneous voice channels, while Advanced IP Services delivers Cisco Express Forwarding and policy-based QoS. PVDM2-32 ensures crystal-clear audio, and SRST safeguards call continuity during central controller maintenance. Benefit: the firm achieves 99.99% voice uptime, meets stringent SOX and GDPR security mandates, and cuts international calling costs by 40%.
Distributed Video Conferencing & Real-Time Collaboration with QoS Prioritization
A global manufacturing company outfits 50 engineering sites with C2821-VSEC-SRST/K9 routers to support HD video conferencing and VoIP collaboration. Advanced IP Services enable class-based weighted fair queuing and Cisco IP SLA monitoring to prioritize voice and video over best-effort traffic. The embedded PVDM2-32 DSPs optimize codec transcoding, while SRST preserves local calling if the WAN link fails. Outcome: engineers experience jitter-free, low-latency conferencing, boosting project turnaround by 30% and reducing travel expenses by $1.2M annually.
