Almost every AI phone agent demo sounds good — that's what a demo is built to do. The harder questions are about what happens once it's handling your real calls, with your real menu, your real hours, and your real edge cases. This checklist covers what actually matters once the novelty wears off.
Setup and customization
Ask exactly what it takes to configure the agent with your specific business details — hours, pricing, policies, and terminology specific to your industry. Some platforms require you to write and maintain prompts yourself; others let you enter your business information directly and handle the underlying configuration automatically. Also ask how long it takes to go from signup to a live, working agent — this varies enormously between vendors.
- •How is the agent configured with your specific hours, menu, or service list?
- •Do you need to write or maintain prompts yourself, or is that handled for you?
- •How long from signup to a live agent taking real calls?
- •Can you test and adjust it before it goes live on your real number?
Escalation and edge cases
No AI agent should try to handle every call itself — the important question is what happens when it hits something outside its depth. Ask how escalation to a human works: does the caller get transferred live, does a team member get an alert, and does the human get the context of the conversation so the caller doesn't have to repeat themselves.
- •What happens when the agent doesn't know the answer or the situation is sensitive?
- •Does escalation happen live, or does someone follow up later?
- •Is the conversation context passed along, or does the caller start over?
Pricing structure
Pricing models vary — flat monthly subscription, per-minute or per-call charges, or tiered plans based on volume. A flat-rate model is easier to budget around if your call volume is unpredictable or seasonal; a per-call model can get expensive fast during a busy period, which is exactly when the agent is doing the most work for you. Ask what happens if you exceed any included volume, and whether there are setup fees on top of the subscription.
Try it as a real caller, not just a spectator
The single best way to evaluate an AI phone agent is to call it yourself and try to break it — ask something off-script, interrupt it, give conflicting information, or ask about an edge case specific to your business. A vendor confident in their product will let you do this freely before you commit to anything.
