"We figured out a more efficient way to monitor system health and resolve failures earlier in lower environments."
"TestMu AI has significantly boosted our testing speed, is easy to implement, and provides exceptional support."
"With 70% faster test execution, TestMu AI helped us achieve faster time-to-market and enhanced CX."
Test Every 8x8 Channel. One Platform.
AI-native agents that place real calls to plan, run, and score inbound agents, outbound campaigns, and conversation quality across 30+ metrics.
Inbound Voice Agent Testing
Test the inbound voice agents you build on 8x8 with real phone calls, and score every call across 30+ metrics, from intent recognition to containment.
Real Phone Calls
Autonomous callers dial your 8x8 agent and monitor duration, transcripts, and DTMF in real time.
30+ Call Metrics
Measure FCR, intent recognition, CSAT, containment rate, voice quality, and STT accuracy.
Latency & Barge-In
Check response latency, interruption handling, and turn-taking on every call.
From the First Ring to Production
Every Stage of Your 8x8 Agent, Covered
Simulate live scenarios before launch, then batch-analyze real production interactions with the same metrics.
Total Quality Coverage for Every Turn
Measure what matters across every interaction, from intent recognition and STT accuracy to bias and hallucination.
UX and Business Ops Metrics
Track the metrics that matter most, from CSAT and sentiment to containment rate and handoff trends.
Confidence by Evaluation
Quality scores are weighted by evaluation volume, giving you a reliable signal on whether your 8x8 agent is ready to ship.
Inside 8x8 Testing On TestMu AI
Real call testing and DTMF, conversation quality, load and CI, plus production call analysis, all scored on real phone calls.
REAL CALL TESTING
Test Voice Agents With Real Phone Calls
Confirm your 8x8 agent answers, understands, and routes correctly. TestMu AI calls it like a real customer, detects DTMF, and verifies the outcome on every call.
Try for free- Real inbound and outbound call testing
- DTMF detection and menu navigation where used
- Call routing, transfer, and fallback verification
CONVERSATION QUALITY
Score Every Turn Like a Real Caller
8x8 agents do not follow a fixed script. Our evaluator scores intent recognition, speech-to-text accuracy, latency, and whether the agent hallucinates or breaks guardrails across many turns.
Try for free- Intent recognition across personas and accents
- Hallucination, bias, and guardrail checks on every turn
- Latency, barge-in, and voice-quality scoring
LOAD & PERFORMANCE
Scale to Concurrent Calls and CI
Traffic spikes and your voice agent has to hold. Simulate concurrent calls, schedule cron-driven runs, and wire regression suites into CI, all on HyperExecute.
Try for free- Concurrent call simulation to stress the agent
- Scheduled and cron-driven regression runs
- CI/CD integration for every release
PRODUCTION ANALYSIS
Catch Regressions Before Your Customers Do
Test calls catch what you script; real calls catch what you do not. Upload production recordings and batch-analyze them so a drop in containment or CSAT never slips by.
Start Testing 8x8- Batch-analyze real production call recordings
- Track quality trends across releases over time
- Flag drops in containment, CSAT, or intent accuracy
Built for Every Layer of 8x8 Testing
Project & Environment Management
Create agents, manage test environments, and scope variables with bulk creation support.
Test Profiles & Personas
Drive interactions with reusable test data and a persona library so you can simulate real users and accents.
Validation Criteria
Define custom, evidence-based pass/fail rules per scenario with High/Medium/Low confidence tracking.
Security & Infrastructure
Execute via HyperExecute with optional secure tunnels for agents behind a private network.
Scheduling Engine
Automate runs using preset frequencies or full custom cron expressions with IANA timezone support.
Observability & Reporting
Monitor runs with unified dashboards, exportable reports, and real-time pass/fail trends.
