C2811-VSEC-SRST/K9 Use Case
Branch Office Telephony Resiliency with SRST Fallback
In a multi-site retail chain, the C2811-VSEC-SRST/K9 with FL-SRST-35 and PVDM2-16 delivers automatic call processing failover when the central Cisco Unified Communications Manager becomes unreachable. This ensures uninterrupted local voice services, achieves 99.9% telephony uptime, and lowers support costs by leveraging built-in DSP resources for emergency site survivability.
Secure Site-to-Site VPN with Integrated Firewall and IPS
A financial services firm deploys the 2811 VSEC Bundle (Adv IP Serv, 128F/256D) to establish high-performance IPsec VPN tunnels between its head office and remote branches while enforcing application-level firewall policies and intrusion prevention. The solution maintains compliance with PCI DSS and scales to 200+ concurrent encrypted sessions, delivering end-to-end data confidentiality and real-time threat protection.
High-Quality Unified Communications over WAN
A manufacturing enterprise leverages the C2811-VSEC with PVDM2-16 and Advanced IP Services to consolidate voice, video, and data traffic on a single WAN link. Quality-of-Service prioritizes VoIP packets while WAN compression and traffic shaping optimize bandwidth usage, reducing latency by 40% and improving Mean Opinion Score (MOS) for remote site calls without additional circuits.
