STRESSTEST — TELEPHONY LOAD TESTING

Prove your voice infrastructure can handle the worst day — before it arrives.

Stresstest simulates thousands of concurrent calls against your voice platform — validating capacity, failover, and call quality under real-world load. Know your infrastructure can handle peak before your customers test it for you.

The first test almost always finds something.

Lines the provider never provisioned · Too few licenses · Load balancing misconfigured · Failovers that don’t fail over · Voice recognition that breaks under load

Tests run from a few hundred calls to 30,000+. The largest ran about 24,000 concurrent calling channels.

Voxology CX engineering, from first-run tests with new customers. An observation from practice, not a measured rate.

The worst time to find out your IVR can’t handle the load is when the load arrives.

Migrations fail. Peak seasons overwhelm. Disaster recovery plans look great on paper. Stresstest lets you prove capacity before the stakes are real — so your first real test isn’t your customers’.

WHAT IT DOES

Load testing built by people who’ve migrated contact centers.

Simulates thousands of concurrent calls

Define your target concurrency — 500 calls, 5,000 calls, 30,000 calls — and Stresstest ramps to that level on your schedule. Real calls from real carriers, not synthetic traffic from a SIP generator.

Validates before you migrate

Run a full load test against your new platform before you cut over. Catch capacity gaps, routing errors, and quality degradation while there’s still time to fix them.

Tests failover and redundancy under load

Simulate a carrier failure or site outage during peak load. Stresstest validates that your failover actually works when it matters — not just in a diagram.

Geographic and carrier diversity in test traffic

Test traffic originates from multiple carriers and regions, mirroring the real-world distribution of your callers. Surface issues that single-carrier testing misses.

Realistic scenario modeling

Model your actual call flows — IVR navigation, DTMF input, hold times, transfers. Stresstest doesn’t just dial; it walks through the experience your customers will have.

Detailed reporting and capacity analysis

Every test produces a full report: call completion rates, latency percentiles, audio quality scores, and failure breakdowns. Know exactly where your limits are.

HOW IT WORKS

From test plan to confidence in days.

Define your scenario

Tell us the target concurrency, call flows, and success criteria.

We generate the load

Real calls from real carriers, ramped to your target over the timeline you choose.

Monitor in real time

Watch call volume, completion rates, and quality metrics as the test runs.

Get a detailed report

Capacity limits, failure points, and recommendations — all documented.

BUSINESS OUTCOMES

What Stresstest protects you from.

De-risk migrations and platform changes

Cloud migrations, vendor switches, and platform upgrades are the highest-risk moments for voice infrastructure. Stresstest validates capacity and quality before you cut over — so a migration doesn’t become a headline.

Prove peak readiness before the peak arrives

Open enrollment. Tax season. Storm response. The events your board asks about. Stresstest lets you demonstrate — with data — that your voice infrastructure will hold. No more crossing fingers on the biggest day of the year.

Catch capacity issues before they become outages

A single peak-event voice failure can cost millions in lost revenue, regulatory exposure, and customer churn. Stresstest finds the breaking point on your terms — when there’s still time to fix it.

USE CASES

Where Stresstest changes the game

Pre-Migration Validation

Validate that your new platform can handle production load before you cut over.

Peak / Seasonal Readiness

Prove your voice infrastructure can handle the biggest day of the year — with data, not hope.

Disaster Recovery Validation

Verify that DR cutover actually works under load — by testing it, not assuming it.

Capacity proven in a test holds until the next release, carrier change, or call-flow edit — which is why Stresstest works best as a standing check on the calendar, not a one-time project.
