Probe · Active call testing

From one call to 100,000 concurrent.
One engine.

Probe is the active synthetic testing product. Place a single functional call to validate a feature, or 100,000+ concurrent calls to find the breaking point of an SBC, media server or IVR cluster. Functional, load, upgrade and routing testing share the same engine, the same dashboard, the same evidence format.

Four testing modes, one engine

Whatever you need to validate, Probe does it.

Functional, load, infrastructure-upgrade and routing testing, all backed by the same forensic capture, the same metrics, the same dashboard.

Functional call testing

End-to-end feature validation: codecs, DTMF, hold, transfer, T.38 fax, call content. Wire it into your release pipeline.

Load & stress testing

100, 1,000, 50,000 concurrent calls. Find the breaking point of SBCs, media servers and IVR clusters. Realistic ramps, not just blast.

Infrastructure upgrade testing

Full feature regression in one go after an SBC, softswitch or PBX upgrade. Ship the upgrade window in hours, not days.

Routing testing

Dial plans, least-cost routing, failover. Multi-carrier, multi-destination. Catch a misrouted prefix before procurement does.

CI/CD & REST API

GitHub Actions, REST API, MCP server, webhooks. Probe blocks bad releases automatically. Ship on Tuesdays.

AI Assistant as test author

“Build a regression that covers DTMF, hold and transfer on these three trunks.” The Agent writes the test book and runs it.

How it works

Same engine, four modes.

1
Pick or build a test book
Predefined library or vibe-author one. Functional, load, upgrade, routing.
2
Wire credentials
SIP, PSTN, multi-trunk. Targets live in encrypted vaults.
3
Run from anywhere
UI, REST API, MCP server, GitHub Actions, webhook trigger. Pick what fits.
4
Analyze with the AI Assistant
Root-cause hints, anomaly correlation, NL search across captures.
Who Probe is for

Voice teams past the hobbyist stage.

If you ship voice changes more than once a quarter, Probe is the product that turns “we deploy and hope” into “we ship on Tuesdays”.

CCaaS & UCaaS vendors

Ongoing platform releases. Regression on every PR. Load test before every major launch. Sprinklr, Genesys, NICE integrators.

Voice AI startups

Regression on the telephony layer separately from the bot layer. Probe handles the SIP/PSTN, Echo handles the bot.

Telcos validating peerings

New peer, new codec, new dialplan rule? Run the full regression in 30 minutes. Catch the bad SDP before customers do.

Integrators & consultants

Pre-go-live readiness checks for end customers. Branded reports satisfy the procurement checkbox.

Try Probe for 14 days. No credit card.

All four products unlocked. Run a 100-concurrent load test on day one, the AI Assistant walks you through it.
