PBX Phone System
PBX stands for Private Branch Exchange. It is the technology that manages how calls move through your business, between extensions internally, and between your team and the outside world. For decades this meant a box of hardware installed on-site. Today most businesses on the Central Coast are switching to hosted cloud PBX, which delivers the same call handling without the hardware, the maintenance bills, or the technician callout fees.
Central Connect manages PBX deployments for businesses across Wyong, Gosford, Tuggerah, and the wider Central Coast. Whether you are moving off an old on-premise system, starting fresh with a cloud phone system, or simply looking to understand your options before making a decision, this page walks through everything you need to know.
A physical PBX unit installed in a comms room or cupboard at your premises. It connects to PSTN or ISDN phone lines and manages extensions through analogue or digital handsets wired directly to the box. These systems are reliable but they are expensive to purchase, require specialist technicians to configure, and cannot support remote workers without additional hardware.
Most traditional PBX hardware in Australia is reaching end-of-life. The copper PSTN network has been progressively shut down and businesses still relying on it face a forced migration sooner or later. Central Connect can assess your current hardware and advise on the most cost-effective path forward.
An IP PBX operates the same way as a traditional PBX but uses internet protocol rather than analogue signalling internally. It still lives on-site as a physical server, but it supports SIP-compatible desk phones and can connect to the phone network via SIP trunks instead of copper lines. This reduces ongoing call costs while keeping your hardware on the premises.
If your organisation has recently purchased an IP PBX or has reasons to keep hardware on-site, pairing it with Central Connect’s SIP trunk plans can bring your line rental costs down significantly without requiring a full system replacement.
A cloud-hosted PBX lives on infrastructure managed by Central Connect, not on a box at your office. Your staff connect using IP desk phones, the 3CX desktop app on a laptop, or the 3CX mobile app on their smartphone. There is no hardware to maintain at your premises. Updates happen automatically. Adding a new extension takes a few minutes rather than a technician visit.
This is the option Central Connect recommends for the majority of new deployments on the Central Coast. It is less expensive to run, more flexible for teams with remote or field-based staff, and delivers features that traditional PBX hardware simply cannot match at the same price.

For most Central Coast businesses, cloud-hosted PBX is the right answer. There are situations where on-premise or hybrid deployment is still valid:
If you are in one of these situations, Central Connect will tell you honestly. We do not push cloud migration on businesses where it does not make sense.

Central Connect is a 3CX Titanium Certified Partner based in Wyong. We deploy, configure, and support hosted PBX systems for businesses across the Central Coast using our own SIP trunking infrastructure and Australian-hosted cloud environment.

That depends on a few factors: how old the hardware is, whether it still receives manufacturer support, and whether it supports the features your business now needs like remote working, mobile apps, or CRM integration. Central Connect offers a free PBX assessment, we look at what you have, what it would cost to keep it running, and whether switching makes financial sense. Many businesses on the Central Coast find the hosted option pays for itself within 12 months.
Yes. If your existing PBX is SIP-compatible, Central Connect can connect SIP trunks directly to it. This replaces your old phone lines, reduces your line rental costs, and keeps your existing phones and configuration in place. It is a cost-effective transitional step for businesses not ready for a full migration.
A PBX is the system that manages your calls, routing them to the right extension, handling IVR menus, and managing call queues. VoIP is the technology that carries those calls over the internet rather than copper lines. A hosted VoIP system like 3CX is a cloud-hosted PBX, it does the same job as a traditional PBX but runs on Central Connect’s infrastructure rather than hardware at your office.
For a small to medium business, the migration typically takes 1 to 2 weeks from sign-off to go-live, including number porting. Larger or more complex deployments with multiple sites or a large number of DDIs are scoped individually. The actual cutover to your new system is scheduled during a low-traffic window and typically completes within minutes.
In almost all cases, no. Central Connect runs your old and new systems in parallel until the number port completes. Your existing phones remain operational right up until the moment the numbers transfer. We test every call flow on the new system before any live traffic is moved.
It depends on what you currently have. 3CX is compatible with most modern SIP-capable IP phones including Yealink, Fanvil, and Grandstream. If your existing handsets are SIP-compatible, they can often be reprogrammed to work with your new system. If not, Central Connect can supply and configure new phones, or your staff can use the 3CX desktop and mobile apps with no physical handset required.
