The Problem
Why Businesses Are Moving to an AI Answering Service
Most people who reach voicemail hang up and call someone else. A traditional professional answering service can help, but it charges per call, leaves callers on hold, and bills extra after hours. Retell answers on the first ring, every time, and you pay only for the minutes used.

Capabilities
What Our Agent Does on a Call
Sends Every Caller to The Right Place:
It works out why someone is calling and routes them to sales, support or billing, with no phone menu to sit through.
Routing can follow your CRM, so callers reach their account owner or region instead of a general queue.
When a person is needed, the agent warm-transfers them along with the full conversation and CRM record.
Answers from Your Own Knowledge Base:
It stays in sync with your knowledge base, so callers hear current answers about hours, services and pricing.
It can look up a caller's record mid-call and tailor what it says.
It can pull from your CRM, ticketing or billing tools over secure webhooks while the call is live.

FAQ
Common Questions
What is a business answering service?
It is a service that answers your company's inbound calls so none of them go unanswered. The version most businesses are moving to now is an AI voice agent that listens, understands ordinary speech, answers the question, and brings in a person when it needs to, instead of sending callers to voicemail or a phone menu.
How much does a business answering service cost?
Traditional services usually charge a monthly fee plus a per-minute or per-call rate, with hold time and after-hours cover on top. Retell is usage-based. The voice engine starts at $0.07/min, and most setups run about $0.13 to $0.31/min once you add the LLM and telephony. You start with $10 in free credits, and there is no premium for nights or weekends. Handling the routine calls automatically is where most of the saving comes from.
What should I look for when choosing an answering service?
Check that it answers around the clock, that the conversation sounds natural, that it escalates to a person cleanly with the context attached, and that it connects to your CRM, calendar and phone line. Clear usage-based pricing and the option to test it on your real calls are worth confirming too.
How does an AI business answering service work?
It connects to your phone system and CRM, listens to the caller, works out what they want, and replies while the call is live. Retell keeps it in sync with your knowledge base, looks up records over secure webhooks, and transfers anything it should not handle to a live rep with the transcript attached.
Can it work for a small business with only a few people?
Yes. It gives a small team the phone cover of a much larger one.You start with $10 in free credits, pay only for what you use, and the agent picks up overflow and after-hours calls so a lead does not slip away while you are busy or closed.
Can I keep my existing business number?
Yes. Connect your current line over SIP trunking, or take a new number from Retell if that suits you better.
Is it secure?
Retell meets SOC 2 Type I and II, HIPAA and GDPR, and will sign a BAA for healthcare use. Optional PII redaction removes personal information from stored transcripts, and data is kept encrypted.
