How Many Calls Can Your Voice AI Handle? Sizing With Real Benchmarks

"Unlimited scale" is not a sizing plan. Enterprises need to know how many simultaneous calls the stack can carry, what happens at burst, and which bottleneck appears first — STT, LLM tokens, TTS, or telephony.

What we measure

• Concurrent live calls and queue behavior
• Token throughput and latency under load
• SIP/trunk limits and regional edge placement
• Degraded-mode behavior when a dependency slows

How to size without guessing

Start from peak historical call volume, add campaign headroom, then validate with a load test on a production-like stack. Voysera deployments — cloud, private, or on-prem — are sized the same way: measured concurrency, not hope.
