AI answering service for after-hours and overflow calls

Friday, 7:05 pm. The office empties and the calls keep coming. The AI answers each one, books what it can, escalates what it must, and your Monday starts with a call log instead of a voicemail queue.

An AI answering service answers your business calls when your staff cannot: after hours, at weekends and when every line is busy. GRX10's AI answers in natural speech, books appointments, escalates urgent callers to a person and logs every call to your CRM.

The short answer

An AI answering service picks up the calls your team can’t take (after hours, overflow and holidays), answering questions, taking messages, booking appointments and escalating urgent calls, all logged to your CRM. GRX10 answers every call 24/7 in all languages*.

FAQ
What is an AI answering service?

Software that answers calls when your team is unavailable, so no lead or customer is sent to voicemail.

When does it hand off to a human?

It escalates urgent or complex calls with the full conversation context; you set the escalation rules.

How much does it cost?

Per-minute pricing with platform and telco as two line items, telco at carrier cost. The first 100 minutes are free.

The gap it closes

After-hours, weekend and overflow call answering

Enquiries peak in the evening and emergencies ignore the calendar. Campaign spikes bury a human desk. The AI takes the after-hours line, the weekend line and the overflow from your day team, with no hold music and no queue.

How it decides

How the AI answering service books, takes messages and escalates

  • Bookable request? It books the slot and confirms on WhatsApp.
  • Routine message? It takes the message, tags it and files it against the caller's record for the morning.
  • Urgent by your rules? It escalates live: transfers to the on-call person or triggers a callback, with the transcript attached.

You define urgent. The rules run at the dispatch layer, not in a rep's judgement at 2 am.

What it costs

AI answering service pricing per minute, with no retainer

Human answering services bill monthly retainers whether the phone rings or sits silent. The AI bills per minute of connected audio, rounded up to the next full minute, and nothing when nothing rings.

  • Billed per minute of connected audio
  • $0 when the line is silent
  • No monthly retainer

A digital lender took 300,000 monthly support calls to round-the-clock coverage with nine humans instead of ninety. Wait times fell from 14 minutes to 2. Satisfaction went up seven days a week, including 2 am on Sunday.
