The Problem
Why Businesses Are Forwarding Missed Calls to an AI Answering Service
Your business already has a number customers know. Call forwarding routes the calls you miss, a busy line, no answer after a few rings, or a call that comes in after hours, to your answering service instead of voicemail. A traditional call forwarding answering service still puts callers on hold and bills per minute once the transfer connects. Retell answers those forwarded calls on the first ring, every time, and you never have to give out a new number.

Capabilities
What Our Agent Does on a Call
Sends Every Forwarded 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, even though the call arrived through a forward.
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
Do I need a new phone number to use Retell?
No. You keep the number your customers already call. You set up call forwarding on your existing line so calls only reach Retell when you're busy, don't answer, or you're closed. Everything else still comes straight to your team like it always has.
How does conditional call forwarding work with Retell?
Conditional call forwarding only sends a call to Retell when a specific condition is met: busy, no answer after a set number of rings, or unreachable, instead of forwarding every call the way unconditional forwarding does. You turn it on through your carrier or phone system, point it at your Retell number, and your main line keeps ringing normally for every call it can answer itself.
Will this work with my existing phone system or PBX?
Yes. If your phone system, cell carrier, or VoIP provider supports conditional forwarding, and nearly all do, you can point busy, no-answer, or after-hours calls at your Retell number the same way you'd forward them to a voicemail box or another employee. No hardware swap and no port-out required.
How much does a call forwarding answering service with Retell cost?
Retell is usage-based starting at $0.07 per minute, with $10 in free credits to start, so you only pay for the forwarded calls it actually handles. There's no per-call charge and no monthly retainer like a traditional answering service bills.
What languages can it handle?
Retell answers forwarded calls in more than one language at the same quality level, so bilingual and multilingual callers get a consistent experience without you paying extra for a second language line.
How fast can I get set up?
You can build your agent from a template and sync it to your knowledge base the same day. Test it against real forwarded calls, then turn on conditional forwarding on your line whenever you're ready to go live.
Can it transfer a forwarded call to a real person?
Yes. When a caller needs a person, Retell warm-transfers the call to your team with the full transcript and CRM record attached, so whoever picks up already has the context instead of starting cold.
