The Problem
Why Businesses Are Moving to a 24/7 Answering Service
Calls do not pause for holidays, long weekends or a 3am emergency. A traditional 24/7 answering service says it covers every hour, but many still route holiday calls to a skeleton crew, charge a premium for December 25th, or put callers on hold during a surge. Retell answers on the first ring, 365 days a year, and you pay only for the minutes used.

Capabilities
What Our Agent Does, Day or Night
Sends Every Caller to The Right Place:
It works out why someone is calling and routes them to sales, support or billing, at 2pm or 2am, 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, even on a holiday.
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, including holiday schedules.
It can look up a caller's record mid-call and tailor what it says, whether it's a Tuesday afternoon or a Sunday night.
It can pull from your CRM, ticketing or billing tools over secure webhooks while the call is live.
Setup
Live in Four Steps
Step 1
Build
Set the agent up in a no-code dashboard or with the API, and point it at your website and FAQs.
Step 2
Test
Run it against the calls you really get, including your busiest overnight and holiday patterns, and confirm it answers well and hands off cleanly.
Step 3
Deploy
Connect your line over SIP trunking or take a new number, then go live on voice, SMS and chat.
Step 4
Monitor
Track resolution and transfer rates and caller sentiment from the dashboard, including how it performs overnight and on holidays, and refine over time.

FAQ
Common Questions
Does the answering service actually work on holidays like Christmas and Thanksgiving?
Yes. Retell answers every call the same way on holidays as it does on a regular Tuesday, including Christmas, Thanksgiving and New Year's. There is no skeleton crew, no holiday surcharge and no reduced coverage.
What does 24/7/365 actually mean with Retell?
It means the agent is answering calls every hour of every day of the year, not just during business hours with an after-hours add-on. The same agent that answers at 10am on a Monday answers at 3am on a Sunday or noon on a federal holiday, with no separate overnight team to hand off to.
What happens if a caller has an emergency at 3am?
The agent is trained on your escalation rules, so an urgent call at 3am gets routed the way you define it, whether that's a live transfer to an on-call number, a text alert to your team, or a message logged with the details you need first thing. Nothing waits until morning that shouldn't.
How much does a 24/7 answering service from Retell cost?
Retell is usage-based starting at $0.07 per minute, with no separate charge for nights, weekends or holidays. You get $10 in free credits to test it on your own calls before committing to a plan.
Can it handle callers who speak a language other than English?
Yes. The agent handles multiple languages with the same answer quality, at any hour, so a caller at midnight gets the same experience as one at midday.
How fast can I get 24/7 coverage running?
Most teams start from a template, sync their knowledge base and are live within days, not weeks. There are no operators to hire, schedule or train for overnight and holiday shifts.
Can the agent transfer a caller to a real person when needed?
Yes, any time of day. When a call needs a human, the agent does a warm transfer with the full conversation and CRM record attached, so your team isn't starting from zero at 2am any more than they would at 2pm.
