Case Study: Maricopa Region 911 achieves real-time emergency call quality and rapid troubleshooting with Corvil

Corvil analytics first responder to assure emergency response services

Maricopa Region 911 delivers emergency call, text-to-911 and location services for the Phoenix metro area — handling 2.4M+ wireless calls each year across 27 PSAPs (about 63% of Arizona’s wireless 911 volume). Because call quality directly affects life‑saving dispatch decisions, the region required “zero tolerance” for degraded calls but was constrained by legacy, disparate tools that provided limited visibility and slowed problem identification and resolution.

Corvil deployed real-time network analytics across data centers and call centers, providing MOS, jitter and packet-loss metrics, full call‑lifecycle visualizations, signaling/media capture, and integration with Splunk via the Corvil VoIP Performance App. The unified view eliminated workflow bottlenecks, reduced mean time to repair to minutes, increased proactive detection and resolution of issues, and improved caller experience, service consistency and staff productivity.
