Scalable Branch Office VoIP Deployment with PSTN Failover on Cisco 2811 Voice Bundle
A mid-sized enterprise deploys the Cisco 2811-V/K9 Voice Bundle with PVDM2-16 and SP Services at its remote branch to support 50+ IP extensions. The 128 MB flash/512 MB DRAM platform delivers carrier-grade QoS, while built-in PSTN failover ensures calls automatically route over alternative trunks during WAN outages. Dynamic dial-peer configuration and voice DSP resource pooling optimize bandwidth and maintain HD voice quality. Outcome: reliable, high-quality VoIP across branches with seamless PSTN redundancy, reducing downtime by 90% and cutting telephony costs.
Secure Multi-Site SIP Trunking and Encrypted Voice Connectivity with Cisco 2811 PVDM2-16
A global services provider uses the Cisco 2811 Voice Bundle and PVDM2-16 to terminate SIP trunks across three data centers, leveraging SP Services for advanced MPLS integration and per-class QoS. IPsec encryption on the 2811 router secures voice traffic over public networks, while hardware DSPs deliver real-time transcoding between G.711, G.729 and T.38 fax streams. Centralized configuration via Cisco IOS grants granular traffic shaping and SIP normalization. Outcome: end-to-end secure SIP voice connectivity with consistent call quality, boosting compliance and reducing trunking expenses by 40%.
High-Density Call Center Integration with PRI, QoS and DSP Acceleration on Cisco 2811
A contact center integrates legacy T1/E1 PRIs and IP seats using the Cisco 2811 Voice Bundle, PVDM2-16 and SP Services to support 200 concurrent agents. The router’s DSP modules handle conferencing, transcoding and voicemail, while policy-based QoS allocates guaranteed bandwidth for critical IVR and ACD traffic. Dial-peer failover and CUBE SIP interworking streamline PSTN and SIP carrier redundancy. Outcome: scalable, high-density telephony with superior voice clarity and 99.99% uptime, enabling a 30% rise in call throughput and improved customer satisfaction.
