Voice AI Testing for Telecommunications

Carrier-Grade Routing, Interop & Resilience

Automatically test telco IVR and voice agents for SIP routing accuracy, ASR/DTMF reliability, and context-preserving transfers—across carriers, SBCs, and PBXs.

Test Suite Generation

Generate Telco Call-Flow Scenarios Automatically

Create comprehensive test suites for multi-level menus, SIP routing decisions, and transfers across carrier networks.

Validate Multi-Level Menus & SIP Routing Logic

  • Test invalid/timeout handling and language selection prompts
  • Validate ASR intent mapping for telco intents (billing, outage, upgrades)
  • Ensure prompts are concise, ordered, and minimize handle time

Dual-Mode Input & ASR Robustness

  • Check DTMF tone detection across SIP trunks and codecs
  • Validate key ASR phrases (billing, technical support, cancel service)
  • Fallback between voice and DTMF with clear reprompts

Preserve Context Across Transfers

  • Validate queue/skill accuracy and overflow behaviors
  • Preserve ANI/CLI, ticket IDs, last intent, and IVR path
  • Handle unavailable agents and callback scheduling gracefully

AI Voice Agent Testing

Comprehensive Telco Voice Agent Validation

Automate testing across provisioning, billing, care, and outage scenarios to reduce transfers and abandonment.

Comprehensive Telco Voice Agent Validation illustration

Validate High-Volume Self-Service Journeys

  • Top-up/balance, data add-ons, upgrades/downgrades
  • Appointment scheduling, outage checks, order status
  • Secure authentication and authorization for account actions

Caller Authentication & Sensitive Data Handling

  • Test MFA with PIN/OTP/security questions and lockout behavior
  • Validate session timeout and secure credential handling
  • Ensure PCI-aligned payment info capture and storage avoidance

Resilience, Errors, and Escalation

  • Test ‘no match’/‘no input’ handling and adaptive retries
  • Validate timeout recovery and intelligent escalation to agents
  • Ensure clear, action-oriented error prompts and post-error routing

Concurrency Load Testing

Network Reliability & Call Volume Simulation

Simulate carrier-grade conditions—concurrency spikes, jitter, packet loss—to protect call quality, routing accuracy, and prompt delivery.

Realistic test scenarios

  • Simulate natural conversation patterns and customer behaviors
  • Generate diverse customer personas with communication styles
  • Create edge cases and challenging scenarios automatically

Multilingual testing

  • Generate test cases in multiple languages and regional variations
  • Test handling of code-switching and mixed language conversations
  • Validate pronunciation and understanding with different accents

Noise simulation

  • Simulate common background noises like traffic, crowds, or music
  • Validate agent performance with varying noise levels and types
  • Test noise cancellation and speech recognition in challenging conditions

Frequently Asked Questions

Answers to common questions teams ask when testing voice agents.

Yes—touchtone (DTMF), ASR-powered voice, and hybrid flows. We validate seamless transitions between modes.

We validate SIP responses, queue/skill mapping, and downstream context preservation to agents (screen pops, case IDs).

We simulate jitter, packet loss, and latency to measure MOS, PDD, prompt delivery, recognition accuracy, and transfer success.

Yes—account/PIN/OTP/security questions, lockout behavior, session timeout, and PCI-aligned payment capture.
