The Problem
Why Businesses Want an Inbound-Only Answering Service
Most callers who reach voicemail hang up and call someone else. A traditional inbound answering service can help, but it's often bundled with outbound dialing you don't need, charges per call, and leaves callers on hold. Retell only answers, it never places outbound calls, and picks up on the first ring while you pay only for the minutes used.

Capabilities
What Our Agent Does on a Call
Routes Every Inbound Call to The Right Place:
It works out why someone is calling, whether it's a support question, a sales inquiry or a general business call, and routes them accordingly, 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
Does Retell only answer calls, or can it also make outbound calls?
Retell's inbound answering service only answers calls that come in. It doesn't place outbound calls, run telemarketing campaigns or make collections calls. If you need outbound calling too, Retell supports that as a separate capability, but this service is built for answering, not dialing out.
What types of inbound calls can it handle?
It handles support questions, sales inquiries, appointment requests, billing questions and general business calls. It answers from your knowledge base and can look up a caller's record to give a specific answer instead of a generic one.
How does it decide where to route a call?
It listens to why the caller is calling and routes them to sales, support or billing without making them sit through a phone menu. Routing can follow your CRM, so callers reach their account owner or region, and a person is brought in with a warm transfer when needed.
How much does an inbound answering service from Retell cost?
Pricing is usage-based starting at $0.07 per minute, with $10 in free credits to get started. You only pay for the minutes your inbound calls actually use.
Can it answer inbound calls in languages other than English?
Yes. It handles multiple languages with the same answer quality, so callers don't need to be routed to a different queue for language support.
How fast can I get an inbound answering service live?
You can start from a template in a no-code dashboard or the API, sync it with your knowledge base and test it against your real calls, then go live the same day on voice, SMS and chat.
What happens when a caller needs to speak to a person?
Retell warm-transfers the call to your team along with the full transcript and CRM record, so your team has the context immediately instead of starting over.
