Business Phone Systems Set Up Properly From the Start

We’ve been setting up and managing phone systems since 2006. It’s one of the services we get asked about most, usually because a business has outgrown its current setup, needs better support for remote work, or wants to move away from old phone lines and hardware.

A good phone system depends on more than the software. Your internet connection, call volume, handsets, mobile users, Microsoft 365 setup, CRM, call routing and support needs all play a role.

We look at how your business communicates day to day, then recommend the right phone system and set it up properly.

Phone Systems We Set Up and Manage

Different businesses need different phone systems. Some teams need a simple hosted VoIP setup. Others need call recording, call queues, mobile access, CRM integration, or a phone system that works across several locations.

We support the main business phone system platforms and can help you choose the right fit.

1. 3CX

3CX is a software-based PBX that runs over the internet. It’s a strong option for businesses that want flexibility, lower running costs and more control over their call setup.

You can run 3CX hosted in the cloud, on-premise, or as a hybrid system. Your team can take calls from desk phones, laptops or mobile devices through the 3CX app.

Features include:

Call recording
Call queuing
Voicemail-to-email
CRM integration
Video conferencing
Live chat
Mobile app access
Call forwarding
Softphone support

CRT is a certified 3CX partner. We handle the setup, configuration, user management and ongoing support.

2. Microsoft Teams Phone

Microsoft Teams Phone works well for businesses already using Microsoft 365. It allows your team to make and receive business calls through Teams, alongside meetings, chat and file sharing.

We handle the setup, SIP trunking or direct routing, number porting and user configuration. Your team can use Teams on their desktop, mobile phone or a dedicated Teams handset.

This can be a good option for businesses that already rely on Microsoft Teams and want their communication tools in one place.

3. Hosted VoIP and Cloud PBX

Hosted VoIP and cloud PBX systems run through the internet, without needing a physical PBX onsite. This gives your business access to features like auto-attendants, call forwarding, voicemail, call routing and remote access.

We set up the system, configure your handsets or softphones, and manage it ongoing. Adding or removing users is straightforward, which makes cloud-based phone systems useful for growing teams, mobile staff and businesses with multiple locations.

What We Handle

Phone System Design and Setup

We assess your current phone setup, internet connection, users, call flow and business needs. From there, we design a phone system around how your team actually works.

This can include hardware selection, cabling, handset provisioning, softphone setup, call routing and full configuration.

Number Porting and Migration

If you’re switching providers or upgrading from an older phone system, we manage the number porting process for you.

We also handle the cutover, testing and configuration so the move is as smooth as possible.

VoIP and SIP Trunking

VoIP uses the internet to make and receive calls. SIP trunking connects your phone system to the public phone network.

We configure SIP trunks, manage the setup, and make sure your phone system works properly with your internet connection and network.

Remote and Mobile Setup

Your team may be in the office, at home, onsite with clients, or moving between locations.

We configure mobile apps, softphones and remote extensions so staff can make and receive business calls from the right number, without needing to rely on personal numbers.

Ongoing Support and Management

Phone systems need proper support after installation. We manage updates, monitor call quality, troubleshoot issues and make changes as your team grows.

That may include adding users, adjusting call flows, updating voicemail, changing ring groups, or reviewing call routing when your business changes.

Need A Custom Solution?

No problem! We offer a wide range of business phone systems to ensure your business gets the solution it needs, no matter the industry

Phone Systems for Different Industries

We set up business phone systems across a range of industries. The right setup depends on how your team communicates, how often customers call, and what needs to happen when someone picks up the phone.

Professional Services

Legal, accounting and consulting firms often need reliable call handling, voicemail-to-email, call recording, CRM integration and call forwarding.

A well-planned phone system helps teams manage client calls clearly, especially when staff are in meetings, working remotely or moving between offices.

Healthcare and Dental

Healthcare and dental practices need phone systems that can handle patient calls, appointment enquiries and internal communication between reception, practitioners and admin teams.

We can set up call queues, auto-attendants and routing rules to help manage busy periods and reduce missed calls.

Retail and Hospitality

Retail and hospitality businesses often need simple, reliable call handling during peak times.

Call queuing, auto-attendants, call forwarding and multi-location support can help teams manage customer enquiries without needing a complicated setup.

Trades and Field Services

For trades and field service businesses, mobile access is often the priority.

We can set up mobile apps and softphones so staff can take business calls on the road while still using the business number.

Multi-Site Businesses

Businesses with more than one location can run one phone system across several sites.

This allows for centralised management, internal transfers, shared directories and consistent call handling across the business.

Business Phone Systems FAQs

What Type of Business Phone System Is Best for a Small Business?

It depends on how your team works.

If your business already uses Microsoft 365, Microsoft Teams Phone may be a good fit. If you want flexibility, mobile access and strong call management features, 3CX is worth looking at. Hosted VoIP can also work well for smaller teams that want a cloud-based phone system without onsite hardware.

We’ll help you compare the options and choose the setup that fits your business.

How Much Does a Business Phone System Cost in Australia?

Pricing depends on the platform, number of users, hardware, call requirements and setup needs.

Some phone systems use per-user pricing. Others, like 3CX, use a flat annual licence based on concurrent calls. Hardware, handsets, SIP trunks, call plans and support can also affect the final cost.

We quote based on your actual setup, so you know what is included.

What Is the Difference Between VoIP, PBX and Cloud Phone Systems?

VoIP is the technology that sends voice calls over the internet instead of traditional phone lines.

A PBX is the system that manages calls, extensions, transfers, queues and routing.

A cloud PBX runs that system in the cloud, so your business does not need to maintain physical PBX hardware onsite.

Most modern business phone systems use a combination of these technologies.

Can I Use Microsoft Teams as My Business Phone System?

Yes. Microsoft Teams can be used as a business phone system when Teams Phone is set up correctly.

This allows your team to make and receive external calls through Teams. We can configure direct routing, SIP trunking, number porting and user settings so it works as part of your broader Microsoft 365 environment.

Can I Keep My Existing Business Phone Numbers?

Yes. In most cases, your existing business phone numbers can be ported across when you move systems or providers.

We manage the number porting process and plan the cutover carefully.

Do I Need New Handsets?

Not always. If your existing SIP handsets are compatible, we may be able to reuse them. If you need new hardware, we can supply and configure options such as Yealink and Grandstream handsets.

Your team can also use softphones on laptops or mobile apps on their phones.

Can Business Phone Systems Support Remote Workers?

Yes. 3CX, Microsoft Teams Phone and hosted VoIP systems can support remote and mobile workers.

Staff can make and receive calls through desktop apps, mobile apps or compatible handsets, depending on the setup.

What Features Should I Look For in a Business Phone System?

Common features include call forwarding, call recording, voicemail-to-email, call queuing, auto-attendants, mobile app access, CRM integration, softphones and reporting.

The right features depend on how your business handles calls and what your team needs each day.
