10 AI Receptionist Failure Modes to Test Before Go-Live
A demo call is optimized to succeed. Your test plan should deliberately try to break the workflow.
- Invented price: caller pushes for a number not in policy.
- Invented ETA: caller asks when a technician will arrive.
- Bad address correction: caller changes street number mid-call.
- Out-of-area acceptance: caller gives a ZIP outside service area.
- Failed transfer loop: destination never answers.
- Wrong emergency priority: routine request escalates or danger does not.
- Double booking: calendar slot is stale.
- Interruption handling: caller talks over the agent.
- Noise sensitivity: jobsite noise corrupts details.
- CRM field loss: transcript exists but dispatch fields are incomplete.
Decision this guide addresses
What must be proven for failure recovery?
A workflow that exposes the problem
A convincing conversation produces a transcript but no usable job request.
Requirements to put in the buying brief
Group failures by recognition, policy, handoff and downstream write. Each category needs a monitoring signal and someone responsible for correction; voice quality alone cannot reveal them.
Configuration details that matter
Keep a written record of scope, accountable staff, required fields and exception paths. Match the caller’s understanding of the next step with the actual operational status.
| Checkpoint | Evidence to request | Reject the pilot when |
|---|---|---|
| Before the call | Written scope for this exact workflow | Only a broad integration or feature label is offered |
| During the call | Accurate request and truthful next-step wording | The caller is given a promise the business cannot keep |
| After the call | Record status and a named owner for exceptions | The transcript exists but nobody can act on it |
Acceptance test before purchase
Test a misspelled address, unknown service, unavailable calendar and failed connector. Keep separate records of what the caller heard and what the operating system received.
Costs beyond the advertised tier
Budget the subscription, the billing unit used by the vendor, connector fees, phone charges and staff time spent correcting exceptions. Illustrative example: a $120 monthly tool plus $30 connector and two staff hours at $25/hour costs $200 before any additional usage. A lower base price does not establish lower operating cost.
Decision rule
Use the evidence from your own pilot to choose the workflow. A missing required action is a purchase blocker even when the advertised price is attractive.
Frequently asked questions
What must be proven for failure recovery?
Group failures by recognition, policy, handoff and downstream write. Each category needs a monitoring signal and someone responsible for correction; voice quality alone cannot reveal them.
What evidence is still missing?
TradeCall Lab has not completed controlled calls for this workflow. The acceptance test above is a proposed buyer test, not a measured vendor result.
How should a failed pilot be handled?
Pause the affected route, preserve the failure record and return calls to the existing staff or voicemail path. Resolve ownership and configuration before expanding coverage.
