L-FL-CME-SRST-25= Use Case
Branch Office VoIP Resilience with CME-SRST 25-Seat E-Delivery RTU on ISR 2900/3900
Scenario: A regional branch office running Cisco Unified Communications Manager Express (CME) relies on an ISR 2900/3900 Series router for VoIP. When the primary WAN link fails, the L-FL-CME-SRST-25 E-Delivery RTU automatically activates SRST mode to host up to 25 concurrent calls locally, maintaining dial-tone, call control and basic voicemail. Benefit: Ensures uninterrupted business-critical voice services during network outages, reduces downtime by over 99%, and preserves SLA commitments without additional hardware.
Regulatory-Compliant Secure Voice & Data Segmentation for Financial Services
Scenario: A mid-tier financial institution must isolate voice traffic from sensitive customer data to meet PCI-DSS and SOX requirements. By deploying the L-FL-CME-SRST-25 E-Delivery RTU on ISR 2900/3900 platforms, IT administrators partition voice and data VLANs, enforce encryption, and leverage local SRST fallback for uninterrupted telephony. Benefit: Achieves full regulatory compliance, minimizes risk of data breaches, and simplifies audits through centralized policy enforcement and secure voice-data segregation.
Centralized Multi-Site Voice Failover & Maintenance Management
Scenario: An enterprise with 12 remote sites schedules nightly WAN maintenance windows, risking telephony interruption. Integrating L-FL-CME-SRST-25 E-Delivery RTU on each site’s ISR 2900/3900 enables automatic SRST activation to handle up to 25 simultaneous calls locally. Centralized scripts push software updates and configuration changes via e-delivery, ensuring consistency across all routers. Benefit: Delivers seamless local call control during WAN maintenance, slashes operational costs by 30% through automated provisioning, and streamlines multi-site voice management under a single pane of glass.
