How to Set Up a GoHighLevel AI Voice Agent for Australian Inbound Calls
Australian businesses lose countless leads when phone calls go unanswered after hours. This step-by-step guide shows how to configure a GoHighLevel AI voice agent that answers calls 24/7 with an authentic Australian accent, books appointments automatically, and follows up with SMS - all without hiring additional staff.
Australian Voice Agent Overview
Australian businesses face unique challenges with phone support - timezone differences, after-hours inquiries, and the need for local accent recognition. While GoHighLevel's outbound calling is currently limited to the US (as of November 2025), their inbound AI voice agent works perfectly for Australian numbers.
The complete setup demonstrated in this tutorial handles:
- 24/7 call answering with Australian-accented AI
- Automatic collection of contact details
- Direct calendar booking integration
- Post-call SMS confirmations
- Sentiment analysis on all conversations
Key capability: The AI agent demonstrated in the tutorial successfully handled a complex scenario where a customer reported their fence was "trampled by elephants," showing the system's ability to maintain professional conversations regardless of unusual inquiries.
Initial Agent Setup
Creating your AI voice agent begins in the Voice AI section of GoHighLevel. The tutorial uses a fencing business example named "Fencing 123" with the agent named "Scarlet" to demonstrate the complete configuration process.
Critical first steps include:
- Naming your agent (avoid overused names like "Sophie")
- Setting the business name that will be announced
- Selecting language (English with Australian accent options)
- Recording/selecting the introductory message
At the 3:20 mark in the video, you can hear the difference between standard and high-quality Australian voice options, with Jessica's voice being the most natural-sounding choice according to the tutorial.
Voice & Behavior Parameters
Advanced settings make the difference between a robotic answering service and a natural-sounding virtual receptionist. The tutorial demonstrates several crucial adjustments:
Conversation Settings
- Call duration limit: Set to 7-8 minutes to prevent endless loops
- Idle frequency: 4 seconds of silence triggers a follow-up
- Interruption sensitivity: Increased for natural conversation flow
Voice Enhancements
- Response speed: Faster setting for natural pacing
- Background noise: Coffee shop ambiance added to avoid "eerie silence"
- Speaking rate: Slightly increased from default
Pro Tip: The background noise feature (demonstrated at 5:45 in the video) significantly improves call quality by eliminating the unnatural silence between responses that makes many AI agents sound robotic.
Knowledge Base Creation
Your AI agent's effectiveness depends entirely on the quality of its knowledge base. The tutorial shows two methods to build this:
Web Crawler Method
For businesses with existing websites, the web crawler can extract relevant information automatically. The demonstration uses a Google Sheet containing structured business information that's processed in about 5 minutes.
Alternative Method
Businesses without websites can create a knowledge base using GoHighLevel's built-in page builder, publishing it to a temporary subdomain for the AI to reference.
The knowledge base should include:
- Services offered
- Pricing ranges
- Business hours
- Service areas
- Common customer questions
System Prompt Configuration
The system prompt acts as the "brain" of your AI agent, determining how it interprets and responds to inquiries. The tutorial provides a complete prompt template that includes:
- Business type (fencing in the example)
- Company mission statement
- Service offerings
- Desired agent personality (friendly, upbeat, caring)
- Conversational tone (warm, professional)
- Target emotional impact (making customers feel confident)
At 9:30 in the video, you can see the exact prompt being customized for the fencing business example before being pasted into the system prompt field in advanced mode.
Critical Note: Advanced mode must be selected before creating the agent, as this setting cannot be changed later. The tutorial emphasizes this at 7:15 to prevent having to recreate agents.
Australian Number Setup
For Australian businesses, proper number configuration is essential. The tutorial demonstrates purchasing a local 04 mobile number ($6.50/month) that supports both calls and SMS.
Key requirements:
- Approved regulatory bundle (shown as green "approved" status)
- Australian number selection (04 prefix recommended)
- Address verification for compliance
The purchased number is then assigned to the AI agent with these settings:
- Agent as backup (answers when humans don't)
- 24/7 availability
- Call forwarding rules
At 12:45 in the video, you can see the complete number purchase and assignment process from start to finish.
Action Automations
The real power comes from connecting your AI agent to automated workflows. The tutorial configures two critical actions:
1. Appointment Booking
By connecting your calendar (Google Calendar, Outlook, etc.), the AI can:
- Check real-time availability
- Book appointments directly
- Send confirmation details
2. Post-Call SMS
Automated follow-up messages improve customer experience:
- "Thanks for your inquiry" confirmations
- Appointment reminders
- Next-step instructions
The tutorial shows how to create these actions at 14:20, including troubleshooting when the system doesn't immediately recognize new templates.
Live Test Results
The tutorial includes a real test call demonstrating the AI agent handling a complex scenario - a customer claiming their fence was destroyed by elephants (16:30 timestamp). Despite the unusual request, the agent:
- Maintained professional tone
- Collected contact information
- Identified needed service (color bond fencing)
- Attempted to book an appointment
After configuring calendar integration, a second test at 18:45 shows the AI successfully:
- Checking available time slots
- Booking a specific appointment (Tuesday at 10:25am)
- Confirming the booking via email
- Ending the call politely
Success Metric: The entire process - from call answer to booked appointment - took under 3 minutes without any human involvement, demonstrating the system's capability to handle real customer inquiries.

Frequently Asked Questions
Common questions about GoHighLevel AI voice agents
As of November 2025, GoHighLevel's AI voice agent only supports outbound calls in the United States. Australian businesses can currently only use the AI agent for inbound call answering.

- Inbound calls fully supported for Australian numbers
- Outbound calling currently US-only
- All other automation features work globally
Your knowledge base should include all information about your business that customers might ask about. The more comprehensive your knowledge base, the better your AI agent can handle diverse customer inquiries.
The tutorial demonstrates using both website content and structured documents to build the knowledge. Even businesses without websites can create effective knowledge bases using GoHighLevel's built-in tools.
- Services/products offered with descriptions
- Price ranges (exact or ballpark figures)
- Business hours and holiday schedules
- Service areas or delivery zones
- Common customer questions and objections

- Knowledge base processing: 4-5 minutes
- Voice configuration: Immediate
- Complete setup to first call: Under 30 minutes
Yes, once you connect your calendar in the Actions section, the AI agent can check availability and book appointments directly. In the tutorial example, the agent successfully booked a fencing consultation at 10:25am on November 25th after checking available slots.

GoHighLevel supports Australian mobile numbers (04 prefixes) which allow both calls and SMS functionality. You'll need an approved regulatory bundle (about $6.50/month) before purchasing numbers.

The tutorial demonstrates using Jessica's voice - one of the Australian-accented options that sounds quite natural. GoHighLevel offers several Australian voice options with adjustable speed and tone settings.
Adding background noise like a coffee shop ambiance (as shown at 5:45 in the video) helps make the conversations feel more natural by eliminating the "eerie silence" common with many AI voice systems.
- Multiple Australian accent options available
- Adjustable speed and tone for natural pacing
- Background noise feature improves realism
Common post-call actions include sending confirmation SMS messages (like the example thanking for the inquiry), email notifications to your team, calendar bookings, and CRM updates.
