Case Study: Mrcall handles thousands of calls with Akka AI-powered call center

Mrcall handles thousands of calls with Akka using just two developers

The customer, Mrcall, is a telecommunications provider that built an AI-powered call center for small and medium businesses. Their challenge was to handle thousands of simultaneous VoIP calls, which requires real-time speech processing, while ensuring no dropped calls or latency. They needed a platform that could manage this scale and be operated by a very small team.

The vendor, Akka, provided a concurrency model where each call is an independent process, preventing failures from cascading. This solution allowed a team of just two developers to build, ship, and operate the entire platform. The results include handling thousands of concurrent calls with minimal infrastructure costs and serving hundreds of SMB customers daily across Italy.
