L-FL-CME-SRST-5= Use Case

Branch Office Telephony Failover with L-FL-CME-SRST-5 on Cisco 3900 ISR

In a distributed retail environment, when the WAN link to the corporate UC platform goes down, L-FL-CME-SRST-5 – Communication Manager Express SRST 5-Seat ESD RTU on the Cisco 3900 ISR automatically takes over local call processing for up to five users. This failover ensures uninterrupted customer service calls, eliminates revenue-impacting outages, and maintains SLA compliance without manual intervention.

Regulatory-Compliant Emergency Calling for Manufacturing Sites

At a high-security manufacturing plant, L-FL-CME-SRST-5 on the Cisco 3900 ISR guarantees that five critical ESD (Emergency Services Direct) extensions remain operational during network outages by switching to Survivable Remote Site Telephony mode. This setup secures continuous access to emergency services, meets regulatory requirements, and protects personnel safety with zero additional hardware costs.

Controlled Voice Feature Testing in Pre-Production

IT teams preparing a UC upgrade deploy L-FL-CME-SRST-5 on a standalone Cisco 3900 ISR to isolate a pilot group of five seats for feature validation. This Survivable Remote Site Telephony (SRST) configuration replicates real-world call scenarios, accelerates testing cycles, and eliminates risk to live users—ensuring a seamless, zero-downtime rollout of new communication services.
