Australian VoIP API: Getting Started Guide for AI Developers

Key Takeaways

Local Infrastructure: Build with a true Australian VoIP provider for low latency and local compliance.
RESTful JSON API: Interact with your phone system using standard JSON payloads and simple HTTP requests.
AI-Ready Instructions: Copy-paste our pre-written LLM instructions into Claude or Cursor to build integrations instantly.
Comprehensive Webhooks: Get real-time event notifications for ringing, answered, and ended calls.

If you're building software in Australia—whether it's a custom CRM, an AI voice agent, or an automated support desk—you eventually hit a wall: you need to connect your code to the real-world phone network. You need an Australian VoIP API.

While global providers exist, they often route traffic overseas (adding latency) or lack deep integration with Australian telecom standards. Click2Call provides a developer-first API built specifically on Australian infrastructure, designed for modern AI builders and "vibe coders."

What Can You Build?

The Click2Call API exposes the core functionality of our enterprise Cloud PBX to your custom software. Here are a few examples of what developers are building:

AI Voice Agents: Connect an Australian 1300 number directly to ElevenLabs and Claude for conversational AI.
CRM Auto-Logging: Automatically log every inbound and outbound call, complete with AI-generated transcriptions and summaries.
Automated Support Desks: Trigger a webhook when a call ends to automatically create a support ticket with the caller's details and call sentiment.
Custom Dashboards: Pull real-time call data to build live wallboards for your sales or support teams.

The "No Experience Needed" Approach

We know that many people building AI tools today aren't traditional telecom engineers. That's why we've optimized our API for LLM-assisted coding.

Inside your Click2Call portal, you'll find a complete set of copy-paste instructions written specifically for AI coding tools like Claude, Cursor, and ChatGPT. You don't need to read pages of API documentation. Just paste our instructions into your LLM, describe what you want to build, and let the AI write the integration code for you.

Example LLM Prompt:

"I'm building a Cloudflare Worker. Here are the Click2Call API instructions: [PASTE INSTRUCTIONS]. Write a script that listens for the 'Ended Event' webhook, fetches the call transcription using the API, and sends it to my Slack channel."

Core API Capabilities

The API is broken down into several key contexts, all accessible via standard JSON POST requests to https://portal.click2call.com.au/api/.

Voice Functions

Manage phone lines, enable/disable call recording programmatically, and download voicemail or auto-attendant audio files.

AI Functions

Fetch call transcriptions, retrieve AI-generated call summaries, get sentiment analysis data, and convert text to speech (TTS).

Webhooks

Receive real-time HTTP POST payloads for ringing, answered, ended, and missed calls, plus notifications when AI analysis is complete.

Account Functions

Pull detailed calling records, check account balances, retrieve billing summaries, and manage channel limits.

Authentication

All API queries must be authenticated using a Token-based system. You generate your secret token within the Click2Call portal. This token is passed in the header of your JSON requests, ensuring your data remains secure.

"Click2Call bridges the gap between traditional Australian telecommunications and modern AI software development."

Getting Started

API access is included free with every Click2Call Cloud PBX account. You don't need a special enterprise plan to start building.

Sign up for a 7-day free trial, grab your API token from the portal, and explore the Developer API to bring your software to life.
