TestMu Outbound Phone AgentOutbound Phone Agent

Evaluate Outbound Sales Dialers and Proactive Calling Agents

Evaluate outbound dialers with dedicated number pools, passive monitoring, and noise simulation.

  • Reserve dedicated outbound number pools with country code selection.
  • Monitor live outbound calls without disrupting the conversation.
  • Configure voice selection, response timing, and 15 noise presets.

TestMu Scenario GenerationScenario Generation

Auto-Generate Phone Agent Test Scenarios from Your Docs

Upload call scripts or connect JIRA and Confluence to auto-generate 60-100+ test scenarios.

  • Upload PDFs, call scripts, or IVR flow documents as knowledge sources.
  • Auto-generate scenarios with validation criteria and Postman imports.
  • Run real-time multi-turn interactions in the playground.

Complete Phone Calling Agent Coverage

Confidence by Evaluation Volume

HIGH (100+ evaluations), MEDIUM (50-99), LOW (20-49), VERY LOW (below 20). Confidence calibrates against evaluation volume.
