Business Phone Systems in Australia

A reliable, well-featured business phone system is the foundation of effective customer and team communication. Whether you're equipping a small office or a large multi-site operation, the right business phone system improves call management, supports your team wherever they work, and gives your business a professional presence from day one.

This directory lists the leading business phone system suppliers operating in Australia. Browse all suppliers below or use the filters to find vendors that specialise in a specific type of system or feature set.

What is a Business Phone System?

A business phone system is a multi-line telephone platform that manages inbound and outbound calls for your organisation — giving your team access to professional call handling features that go well beyond a standard residential phone line.

Modern business phone systems range from cloud-hosted VoIP solutions that require no on-site hardware, through to full on-premises PBX installations for organisations with specific infrastructure or security requirements. Most businesses today are moving toward cloud and VoIP-based systems for their flexibility, lower cost, and support for remote and hybrid workforces.

The three main types of business phone systems available in Australia are:

VoIP & Cloud-Based Systems

Hosted in the cloud and delivered over your internet connection. No on-site hardware required, with per-user monthly pricing and easy scalability. The most popular choice for Australian businesses today.

Cloud PBX

A fully hosted Private Branch Exchange system — delivering enterprise-grade call management features (IVR, call queuing, auto-attendant, recording) without the cost or complexity of on-premises hardware.

Unified Communications (UC)

Integrates voice calling with video, messaging, collaboration, and presence tools into a single platform. Ideal for businesses that want to consolidate communications and support hybrid teams across multiple locations.

On-Premises PBX

Traditional hardware-based systems installed and managed on-site. Higher upfront cost but suited to organisations with specific security, compliance, or infrastructure requirements.

PSTN & Traditional Systems

Public Switched Telephone Network (PSTN) systems using traditional copper line infrastructure. Being phased out across Australia as the NBN rollout continues — businesses still on PSTN should plan their migration.

Microsoft Teams Phone

Business phone system functionality delivered natively within Microsoft Teams — allowing organisations already using Teams to add PSTN calling without a separate phone platform.

PSTN Migration in Australia

Telstra has been progressively retiring its copper network infrastructure across Australia. If your business is still operating on a traditional PSTN system, now is the time to plan your migration to a VoIP or cloud-based business phone system. Contact one of the suppliers below for migration advice.

Business Phone System Features to Consider

Modern business phone systems come with a wide range of features beyond basic calling. Use the Filter by Solution/Service dropdown below to find suppliers that specialise in a specific feature or capability — or use this as a checklist when evaluating systems:

  • Auto Attendant: Automatically greets callers and routes them to the right department or person without a receptionist — professional, consistent, and available 24/7.
  • Call Queue Management: Manages incoming call volumes by placing callers in a queue with hold music or messages, routing to the next available person and reducing missed calls.
  • Call Recording: Records inbound and outbound calls for quality assurance, compliance, training, and dispute resolution.
  • Advanced Call Control: Call transfer, call park, call flip, busy lamp field (BLF), and call barge — giving teams full control over how calls are handled day to day.
  • Analytics & Reporting: Real-time and historical reporting on call volumes, wait times, missed calls, and team activity — giving managers the visibility to optimise performance.
  • Cloud PBX & Hosted PBX: Fully cloud-hosted PBX delivering enterprise call management features with no on-site hardware, on a per-user monthly subscription.
  • NBN Phone Systems: VoIP-based business phone systems optimised for NBN connections — important for businesses that have already migrated or are planning to migrate from the copper network.
  • SMS Capabilities: Business SMS integration that allows teams to send and receive text messages through the same platform managing their voice calls.
  • Unified Communications: Integration of voice, video, messaging, and collaboration tools into a single platform — reducing tool sprawl and improving team communication.
  • Video Conferencing: Built-in or integrated video calling for internal meetings and external customer or partner calls.

Benefits of a Modern Business Phone System

Upgrading to a modern business phone system delivers improvements across customer experience, team productivity, and operational efficiency. Key benefits include:

  • Professional Call Handling: Auto-attendants, IVR menus, custom greetings, and intelligent call routing ensure every caller reaches the right person efficiently — regardless of your business size.
  • Scalability: Cloud and VoIP business phone systems scale up or down as your team grows or changes, with no hardware upgrades required.
  • Remote & Hybrid Support: Cloud-based systems work equally well for office, remote, and hybrid teams — your business phone system travels with your employees wherever they work.
  • Cost Reduction: VoIP and cloud systems significantly reduce call costs compared to traditional landlines, particularly for businesses with high call volumes or multiple locations.
  • Advanced Features: Voicemail-to-email, call recording, call analytics, conferencing, and call queue management are now standard inclusions in most modern business phone systems.
  • Integration Capabilities: Modern business phone systems integrate with CRM platforms, helpdesk software, and contact centre solutions — giving teams full context on every caller.
  • Reliability: Cloud-hosted systems offer built-in redundancy and failover, ensuring your phones stay up even during local outages or hardware failures.
  • Detailed Reporting: Call analytics and reporting give managers visibility over call volumes, wait times, missed calls, and agent performance.
