Common problems
- Multiple people speaking near the caller
- Low-quality mobile microphones
- Delayed audio
- Caller interruption
- Long silence while the caller checks information
Configuration checklist
- Use short prompts and direct questions
- Confirm important answers
- Ask the caller to repeat only when needed
- Tune interruption behavior
- Provide a human fallback for poor audio quality
Do not rely only on perfect test calls. Include noisy, interrupted, and low-bandwidth calls in QA.
