As of 13 August 2026, AI can only partly answer customer questions by phone.
This still needs a person who signs their name to it.

If this goes wrong: the agent gives a confident answer that does not fit the customer’s case, wastes the caller’s time and sends the issue to your staff after trust has already been lost.

How to actually do it
- Open your current help centre, product documentation, price list, delivery information, refund policy and opening-hours records, then remove anything obsolete.
- Paste the approved documents and escalation rules into the prompt, including which questions require a human and the phone number or route for transfer.
- Choose a voice-agent platform such as Voiceflow and connect it to your business phone system or approved calling provider.
- Configure the agent to answer only from the supplied content, ask one clarification question at a time and transfer complaints, account-specific requests and uncertain answers.
- Create a test list covering ordinary questions, ambiguous wording, out-of-date information, complaints, payment issues, personal-data requests and requests for a human.
- Call the test number for every scenario, compare each answer with the current source document and record whether the transfer happened when required.
- Give the approved test recordings and transcripts to a customer-service colleague, fix failed answers and escalation routes, then launch for a limited set of tier-1 calls before expanding coverage.
Prompt
You are a telephone customer-service agent for [BUSINESS NAME]. Answer only questions covered by the approved information below. Use a calm, plain British tone and keep each answer concise. Do not invent prices, availability, delivery times, policies, guarantees or account details. If the information is missing, contradictory or specific to the customer’s account, say that you cannot confirm it and offer a transfer to a human adviser. Ask one clear question at a time when you need clarification. For complaints, safety concerns, payment disputes, cancellations outside the stated policy, threats of legal action or requests for personal data, transfer the call to a human. Before ending, briefly confirm the customer’s requested outcome and state any next step. Approved information: [PASTE CURRENT HELP CONTENT, PRICE LIST, POLICIES, OPENING HOURS AND ESCALATION RULES HERE].

What it gets wrong
- Cannot reliably understand unusual customer circumstances that are absent from the supplied material.
- Cannot know that a price, stock position or policy has changed unless your connected information is updated.
- Cannot take responsibility for an incorrect answer; the customer still deals with your business.
- Cannot replace a person for complaints, sensitive account issues, payment disputes or requests that need judgement.
- Voice testing takes real calls or realistic call simulations, not just a quick document check.
What caps this at PARTLY: context depth, verification cost and legal accountability.

FAQ
- Can AI answer customer questions over the phone?
- Yes, for repeatable tier-1 questions covered by your approved help content. It is PARTLY rather than a complete replacement for staff because unclear, account-specific and complaint calls need a human route.
- Can I use AI to answer my business phone?
- You can connect a voice agent to a business phone system and give it your help content. It must have clear transfer rules and current information, or it will give callers confident answers that may be wrong.
- Will an AI phone agent replace customer service staff?
- It can absorb repeated first-line questions and leave staff to handle exceptions. It does not replace the judgement, responsibility or relationship work involved in complaints and unusual cases.
- How do I stop an AI phone agent giving wrong answers?
- Limit it to approved documents, prohibit invented information and configure transfers whenever the answer is missing or account-specific. Test spoken calls against your current policies and have a customer-service colleague approve the results before launch.
