Do I Need a Landline for My Business in Perth?

Do I need a landline for my business in Perth is one of the most common questions business owners ask when setting up a new office, relocating, or reviewing their communications setup.

If you’re planning changes to your phone setup, start with the bigger picture first: our Business Phone Systems Perth guide explains modern options like VoIP, 3CX, number porting, and cutover planning.

For most modern Perth businesses, the answer is no. Advances in business phone systems Perth businesses now use mean calls can be made and received without traditional landlines — although there are a few important exceptions.

This article explains when landlines still make sense, when they don’t, and what most Perth and WA businesses use instead.

Across Western Australia, businesses are increasingly moving away from copper-based phone lines as providers transition to cloud and VoIP-based services that offer greater flexibility and reliability.

What Is a Landline in a Business Context?

A traditional landline is a fixed phone service delivered over copper or fibre infrastructure to a physical address. Historically, landlines were required for business phones, fax machines, EFTPOS terminals, and alarm systems.

Today, many of these services no longer require a dedicated landline, as cloud-based alternatives are widely available.

Why Most Perth Businesses No Longer Need a Landline

For the majority of small and medium businesses, landlines are no longer necessary due to the rise of cloud-based phone systems.

• Internet-based phones (VoIP) are more flexible
• Phone numbers are no longer tied to a physical address
• Staff can answer calls from mobiles or laptops
• Office moves are faster and less disruptive

This flexibility is particularly valuable when moving offices, as cloud phone systems help businesses stay reachable during transitions.

What Do Businesses Use Instead of Landlines?

Cloud-Based VoIP Phone Systems

VoIP (Voice over Internet Protocol) phone systems use an internet connection to make and receive calls. These are now the most common business phone systems Perth organisations rely on.

• No physical phone lines required
• Lower ongoing costs
• Easy to scale up or down
• Supports remote and mobile staff

3CX Phone System

3CX is a widely adopted business phone system across Western Australia. Many Perth businesses choose 3CX phone systems because they support desk phones, mobiles, and web browsers and can be hosted in the cloud or on-premise.

Businesses choose 3CX because it allows them to:

• Keep existing phone numbers
• Remove dependence on physical phone lines
• Support remote and hybrid teams
• Add call queues, IVRs, call recording, and reporting

If you plan to keep your existing number, it’s important to understand how long it takes to port business phone numbers in Australia before cancelling any current services.

When a Landline May Still Be Required

Although uncommon, some businesses may still require a landline:

• Legacy alarm systems
• Older EFTPOS terminals
• Industry-specific compliance requirements
• Locations with unreliable internet connectivity

Even in these cases, alternatives often exist that remove the need for a traditional landline.

Does the NBN Change the Need for Landlines?

With the rollout of the NBN, many copper landlines have been replaced with digital voice services that still rely on power and internet connectivity. This reduces the historical reliability advantage of landlines.

Common Misconceptions About Business Landlines

• “Landlines are more reliable” — not always true
• “You need a landline to look professional” — modern phone systems handle this
• “VoIP has poor call quality” — modern VoIP is highly reliable on business-grade internet

Bottom Line

So, do I need a landline for my business in Perth? For most businesses, the answer is no. Cloud-based phone systems provide greater flexibility, lower costs, and simpler scalability — particularly for growing or relocating organisations.
