Capacity Planners, Network Engineers & Infrastructure Managers

What happens to call quality at 10,000 concurrent calls? Do you know — or hope?

Your infrastructure handles 2,000 calls today. Business is growing. At what point does audio and video quality degrade? 5,000? 8,000? 12,000? You won't know until customers complain — unless you test first. CallMeter incrementally increases load, measures quality at each step, and identifies the exact inflection point. Run from CallMeter cloud or deploy workers on your own infrastructure to test from the production network path.

What CallMeter Delivers

Incremental Load Ramping

Gradually increase concurrent calls from baseline to target — 100, 500, 1K, 5K, 10K — measuring quality across 70+ dimensions at each step.

Quality Inflection Point Detection

Identify the exact call count where quality scores drop below acceptable thresholds. Know your ceiling before your customers find it.

Continuous Monitoring After Testing

Once you know your limits, set up continuous probes that validate you stay within safe thresholds as traffic grows organically.

Know Your Infrastructure's True Limits: A Deep Dive

The Problem

You know your infrastructure handles today's traffic. But growth means more concurrent calls, and you don't know where voice and video quality starts to degrade. Waiting for customer complaints to discover capacity limits is expensive and reputationally damaging.

How CallMeter Solves It

Incrementally ramp load from 100 to 10,000+ concurrent calls. At each step, CallMeter measures quality across 70+ dimensions. When quality drops, it identifies the inflection point and root-causes the bottleneck — bandwidth, session limits, or codec overhead.

What You Get

A capacity profile for your infrastructure. The exact call count where quality degrades, the bottleneck that causes it, and evidence to justify expansion budget to leadership.

How It Works, Step by Step

1

Baseline

Establish current call volume and quality measurements.

2

Ramp

Incrementally increase load — 100, 500, 1K, 5K, 10K concurrent calls.

3

Identify

Find the inflection point where quality drops below threshold.

4

Plan

Use bottleneck analysis to plan targeted expansion.
