How to handle spam and sales calls with an AI voice agent

InfiVoice ยท 2026-11-14

Unwanted calls eat time. An AI voice agent can answer every call, spot the ones that are not for you and end them politely, so your team only hears from people who matter.

Step 1. Decide what counts as unwanted

List the calls you do not want, such as cold sales pitches, survey requests and recorded messages. Be specific, so the agent can tell them apart from real customers.

Step 2. Ask a simple opening question

Have the agent ask who is calling and what it is about. Real customers answer quickly. Most unwanted callers either hang up or give a vague reply.

Step 3. Write a polite closing line

Give the agent a short, friendly way to end the call, such as saying the team is not taking sales calls and thanking the caller. Keep it calm and never rude.

Step 4. Protect the real callers

When the agent is unsure, it should treat the caller as a customer. A wrongly blocked customer costs more than a few extra calls.

Step 5. Offer a route for genuine partners

Some sales calls are useful, such as a supplier you work with. Tell the agent to take a name and a message for those and pass them to the right person.

Step 6. Review the call log

Read the transcripts now and then. Look for real customers who were sent away and adjust your instructions. Our guide on measuring performance shows what to track.

Step 7. Test before going live

Call the agent yourself as a salesperson, a customer and someone unclear. Fix any case that ends badly. Our testing guide covers this.

What it costs

InfiVoice bills in credits, and one credit equals 60 seconds of call time. The Free plan includes 100 credits. Pro costs $79 per month with 250 credits.
