Operational tier · Voice

Your phone line, answered every time, day or night.

It picks up your main line around the clock, answers the routine questions callers actually ask, takes messages and details, and transfers live to the right person with context. No more missed calls, no more voicemail black holes.

What does an AI call answering agent do?

A call answering agent is a virtual receptionist. It answers every inbound call to your line (24/7, in Greek and English) greets the caller, answers routine questions from your knowledge base (hours, location, pricing, status), captures the caller's details and reason, and routes or transfers to the right person or queue with a summary. Anything it can't handle goes to a human, not a dead end. Operational tier, built on Claude. Best for reception and overflow; for proactive outbound calls and qualification, see the Voice Agent.

FAQ

Questions about the Call Answering Agent.

How is this different from voicemail or an IVR menu?

Voicemail and IVR make the caller do the work, leave a message, press 1, wait. The agent actually answers the question or gets the caller to the right person in one natural conversation, and never just records into a void.

Can it transfer to the right team member?

Yes. It uses your routing rules and team directory to identify who's needed and warm-transfers with a spoken summary. If nobody's free, it captures a structured message and delivers it instantly.
