The Problem
Why Remote and Distributed Teams Are Moving to a Virtual Phone Answering Service
Remote and distributed teams don't have a front desk, so calls go to voicemail or bounce between personal cell phones. A traditional virtual answering service can pick up the slack, but it still charges per call, puts callers on hold, and needs you to route messages by hand. Retell answers on the first ring from any virtual number, every time, and you pay only for the minutes used.

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 no matter which city or timezone your team works from.
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 to buy new hardware for a virtual phone answering service?
No. Retell runs entirely in the cloud, so there's no desk phone, PBX box or extension to install. You just connect your existing virtual number or take a new one, and the agent starts answering calls.
Can Retell work with the virtual number I already have?
Yes. Retell connects to your current virtual number over SIP trunking, so you keep the number your customers already know. If you don't have one yet, you can take a new number directly through Retell instead.
Is this a good fit for a fully remote or distributed team?
Yes. Since there's no physical office or shared desk phone, Retell gives a remote or distributed team a single professional number that answers the same way no matter where each person is working from, and warm-transfers callers to whoever is available.
How much does a virtual phone answering service from Retell cost?
Retell is usage-based starting at $0.07 per minute, with $10 in free credits to get started. You only pay for the minutes the agent actually spends on calls.
Can the agent answer in more than one language?
Yes. Retell handles multiple languages with the same answer quality, so you're not paying extra or routing calls to a separate multilingual line.
How fast can I get a virtual phone answering service live?
You can set up the agent in a no-code dashboard or with the API, point it at your website and FAQs, and test it against real calls the same day. There's no operator training or onboarding period to wait on.
What happens when a caller needs to speak to a real person?
The agent warm-transfers the call to your team along with the full transcript and CRM record, so whoever picks up already has the context and the caller doesn't have to repeat themselves.
