FL-E-SRST-25 Use Case
Seamless WAN Failover for 25 Retail Branches with FL-E-SRST-25 UMG License
Scenario: A national retail chain deploys the FL-E-SRST-25 UMG license across 25 branch stores to enable Emergency Session Routing (E-SRST) when primary WAN links fail. During an ISP outage, each store’s Cisco IP phones automatically register to its on-site E-SRST node, preserving voice services and POS transaction processing. Benefit: Ensures continuous customer service, eliminates transaction downtime, and protects revenue during network disruptions.
Secure Telemedicine Continuity for 25 Regional Clinics Using E-SRST Nodes
Scenario: A healthcare provider implements the FL-E-SRST-25 UMG license for 25 rural clinics to maintain critical telemedicine consultations and emergency call routing during network failures. When connectivity to the central data center is lost, local E-SRST nodes instantly switch call control, enabling uninterrupted patient-doctor video calls and secure EMR access. Benefit: Guarantees 24/7 clinical communication, enhances patient safety, and meets HIPAA compliance under adverse network conditions.
Resilient Manufacturing IoT Control in 25 Facilities with FL-E-SRST-25
Scenario: A global manufacturer leverages the FL-E-SRST-25 UMG license across 25 production plants to support local IoT device management and voice alarms during WAN outages. If the link to headquarters fails, E-SRST nodes handle on-site SIP trunking, voice alerts, and real-time machine telemetry routing to local control systems. Benefit: Maintains uninterrupted plant operations, prevents production delays, and safeguards equipment through reliable local voice and data services.

Questions & Answers
What is the FL-E-SRST-25 UMG license?
The FL-E-SRST-25 UMG license is a Universal Messaging Gateway entitlement that enables up to 25 E-SRST nodes or sites for secure session routing and survivable remote site telephony.
How many E-SRST nodes does FL-E-SRST-25 support?

Which platforms are compatible with FL-E-SRST-25?
FL-E-SRST-25 is compatible with Cisco Unified Communications Manager (CUCM) versions 11.x and later, and integrates seamlessly with supported ISR and ASR routers running Cisco E-SRST.
How do I activate the FL-E-SRST-25 license?
To activate FL-E-SRST-25, log into the CUCM License Manager, upload the Cisco Smart License file, and assign the 25-node entitlement to your E-SRST deployment.
Can I upgrade FL-E-SRST-25 to support more nodes?
Yes. You can purchase an incremental upgrade or a higher-tier UMG license to expand support beyond 25 E-SRST nodes without disruption.
How do I renew my FL-E-SRST-25 license?
License renewal is handled through Cisco Smart Accounts. Submit a renewal order before expiration and reapply the updated certificate in the CUCM License Manager.
Does FL-E-SRST-25 include technical support?
The FL-E-SRST-25 product includes standard SMARTnet support, providing 24×7 access to software updates and Cisco TAC assistance during your support contract term.
What are the key benefits of the FL-E-SRST-25 license?
Key benefits include automated failover for remote sites, centralized license management, reduced on-site hardware, and robust survivability for IP telephony.
How do I verify the status of my FL-E-SRST-25 license?
In CUCM, navigate to System > Licensing > License Usage. The dashboard displays active E-SRST entitlements, node count, and expiration dates for FL-E-SRST-25.
