Large businesses and enterprises have significant communications needs. A single line in with a receptionist won’t do: you must juggle several calls simultaneously. Your employees need easy ways to communicate and collaborate. Enterprise phone systems allow you to do all this and more, and Business Telecom has the latest in phone technology and services, with market-leading reliability and uptime.

We’ve partnered with the top names in enterprise phone systems, Avaya, Cisco, and Panasonic, to bring you the best business phones that offer the latest features. In some cases, we may even be able to use the equipment you already have.

Our experts will help you find the perfect phone system for your needs, whether you have a single office, multiple locations, or a remote workforce. And as your business evolves, our scaleable solutions adapt to your business’s changing needs.

And we’re not here to just sell you something. Our highly-trained experts will walk you through the setup process, show you how to get the most out of your new enterprise phone system, and answer any questions you may have. Our support team is available 24 hours a day, seven days a week.

The Best Enterprise Phone Systems

When looking for a new phone system for your business, which one is “best” will depend on a few variables:

  • Your current system: Many customers come to us with phone systems already in place. We always start here. We’ll ask you what you like and don’t like about your current system and any “must-have” features. We’ll also ask questions about how many users you’ll need to support and the locations of your users (one office, multi-office, WFH).
  • Broadband access: If you’ve switched over to NBN, great! All of our solutions are NBN-ready. If you aren’t or are connected to broadband via other means, we’ll be glad to discuss your options.
  • Desired features: A new enterprise phone system is an excellent opportunity to utilise modern collaborative tools. Our phone systems offer valuable features like whiteboards, file sharing, and smartphone apps. Each enterprise is different, and we’re happy to customise a plan for your needs.
  • Budget: Large business phone systems are a significant expense even for the biggest businesses, sometimes running into the tens if not hundreds of thousands of dollars. Business Telecom can work with your budget, often finding ways to lower your telecommunications costs, helping your bottom line.

Must-Have Large Business Phone System Features

While we are happy to customise enterprise phone systems to our customer’s unique needs, we find that there are a few features that we think any business should have, large or small. We most commonly recommend:

Voicemail to Email

There’s no need to call in to check your voicemail. Our phone systems send voicemails to your inbox, so you know who’s called no matter where you might be.

Hunt Group

Get your customer to the right person the first time with automatic routing of the call to the next available representative after they’ve chosen from your menu.

Auto attendant

Modern enterprise phone systems don’t require a receptionist. We’ll ensure your caller gets to the correct department using our easy-to-use auto attendant.

Music on hold

Silence is uncomfortable, and long hold times are a recipe for losing your customer. Enterprise phone systems with music on hold helps keep your caller engaged.


Today’s workforce isn’t tied to the office. Large business phone systems from Business Telecom allow you to put all the capabilities of a business phone on your employee’s mobiles.

Conference Calls

No matter where your employees are, you can conduct virtual meetings with high-quality conference call functionality for both video and audio.

Call Recording

Maintain a high level of customer care by recording all incoming and outgoing calls for later review.

Call Accounting

Our enterprise phone systems log phone usage and costs, all accessible from a central dashboard.

Frequently Asked Questions

An enterprise phone system is a group of communications technologies and devices that offer features useful in office environments. In addition to phones, these phone systems can also include software-based phones via a desktop or mobile app and audio and video conferencing. Traditional enterprise phone systems used standard copper phone lines. However, with the launch of the NBN throughout Australia, modern phone systems now use VoIP. Enterprise phone systems can also include Unified Communications (UC) technology that links the phone system with other communications tools, such as instant messaging and presence.

Unfortunately, there is no set cost for enterprise phone systems as the needs of businesses vary considerably. However, for most enterprise setups, the initial investment is several thousand dollars, with plans costing most larger companies $1,000+ per month, depending on the number of users on your phone system. We strongly recommend that you contact us to inquire about pricing, as we’d be able to give you a much more specific estimate based on your unique needs and communications goals.

In most cases, yes. Slower broadband options like ADSL and others will not have the bandwidth necessary, so a standard analogue business system is, unfortunately, the best option. However, with the NBN slated to cover 95% of Australians, this is not (or won’t be) an issue. There are some exceptions. Modern large business phone systems will be compatible if you’re connected to broadband via mid-band ethernet or other high-bandwidth options. Contact us to learn more about the specific options available at your business’s location.

Business Telecom offers large business phone systems from the most reliable brands – Avaya, Cisco, and Panasonic. These companies offer a wide array of options for businesses, both large and small. If you have VoIP phone system equipment already from other manufacturers or analogue phones you’d like connected to your new enterprise phone system, in many cases, we can transition your devices to your new phone system without issue.
