An AI receptionist that knows your business, and when to hand over.
Grendesign designs and builds custom AI receptionists and voice agents for Australian organisations with high call volumes. Your agent answers 24/7, books and qualifies, answers common questions from your own information, and passes complex or sensitive calls to the right person with a summary. It connects to your phone system, calendar and CRM.
For clinics, multi-site services and firms where missed calls are missed revenue.
- Custom-built, not a template
- Connects to your CRM and calendar
- Clear escalation rules
Off-the-shelf AI receptionists sound fine. Until a real caller rings.
Plug-and-play tools are built for a plumber with one phone line. Larger organisations have triage rules, several locations, privacy obligations and systems that need updating. A voice agent that can’t handle those creates more work, not less.
After-hours calls go nowhere
Prospects ring once. If no one answers, they call the next business on the list.
Front desk overload
Skilled staff spend the day answering the same five questions and rescheduling appointments.
Generic bots damage trust
A voice agent that guesses, or won’t transfer, does more harm than voicemail.
What your voice agent can do
Designed around your call types, your rules and your systems.
Answer and qualify
Takes every call, asks the right questions for each enquiry type and records the answers in your CRM.
Book and reschedule
Checks real availability in your calendar or booking system and confirms by SMS or email.
Answer from your information
Uses your approved services, prices, locations and policies. It doesn’t make things up.
Escalate properly
Urgent, sensitive or complex calls go to a person straight away, with a summary so the caller doesn’t repeat themselves.
Multi-location routing
Sends callers to the right site, team or on-call person based on rules you set.
Call reporting
Transcripts, outcomes and trends, so you can see what people are calling about and fix the causes.
How it runs, week by week
One named lead, fixed checkpoints and nothing goes live without your sign-off.

Questions we get asked
What is an AI receptionist?
An AI receptionist is a voice agent that answers phone calls, understands what the caller needs and responds in natural speech. It can answer questions, book appointments, take details and transfer calls to staff.
How is a custom voice agent different from an AI receptionist app?
Apps are built for simple, single-location businesses. A custom agent follows your triage and routing rules, uses your approved information and updates your own systems.
How much does a custom AI voice agent cost?
Costs depend on call volume, integrations and how many call types it handles. There’s a setup project and then ongoing usage and support. We quote after a call audit.
Will callers know they’re talking to AI?
They should. We recommend the agent says so at the start and always offers a person. It builds trust and avoids complaints.
Can it transfer calls to our staff?
Yes, by rules you set, with a short summary sent ahead so staff know who’s calling and why.
Can it book into our existing system?
Usually. Most calendar, practice management and booking systems with an API can be connected. We confirm yours in the audit.
Is it compliant with Australian privacy law?
We design for the Privacy Act: what’s recorded, where it’s stored and how long it’s kept. Some industries have extra rules, which we check with you.
Does it sound Australian?
Yes. We choose a natural Australian voice and test it on real local names, addresses and accents.
What happens if it doesn’t understand a caller?
It asks once to clarify, then hands the call to a person or takes a message. It shouldn’t keep guessing.
How long does it take to go live?
Most projects take six to ten weeks, starting with after-hours calls or one line before going wider.
How many calls did you miss last week?
