Cloud PBX Phone System for Australian Business

Cloud PBX, Hosted PBX, Virtual PBX — One Australian Platform

Whether you call it a cloud PBX, hosted PBX, or virtual PBX, the result is the same: a fully managed phone system running on Simtex infrastructure in Australian data centres, with no hardware to buy or maintain on your premises. The terms are used interchangeably in the Australian market — all refer to hosting your business phone system in the cloud rather than running a physical PABX on-site.

Simtex's hosted PBX platform is built for Australian businesses of every size, from sole traders needing a single extension to national organisations running hundreds of extensions across multiple sites. Everything is managed from a web-based admin portal — add extensions, configure call flows, and update routing without touching any hardware.

NBN-Compatible Hosted Phone System

Simtex Cloud PBX is designed to work over any Australian broadband connection, including NBN. If your office has recently migrated to NBN — or if you're planning ahead — your phone system can migrate at the same time with no disruption to your numbers or call flows.

• No dedicated phone lines required — voice traffic runs over your existing NBN or business broadband connection
• Keep your existing numbers — port your current landline or 1300 numbers to the platform
• Ready on day one — Simtex pre-configures handsets before shipping; plug in and the phone registers automatically
• Australian-hosted infrastructure — calls stay on Australian servers; data residency matters for compliance-conscious businesses

Hosted on Australian Infrastructure

Simtex's voice platform runs across multiple Australian data centres. If one facility has an outage, high-availability failover routes calls automatically to a secondary site. You get carrier-grade reliability without paying carrier-grade prices.

Hosted PBX Plans for Every Business Size

A common misconception about hosted phone systems is that they're expensive. Simtex Cloud PBX uses a per-extension pricing model — you pay per phone or user, not for unused capacity. A small business with two staff can start on two extensions and add more as the team grows. There are no upfront PABX hardware costs, no line cards to buy, and no PBX software licences to renew.

From Small Business to Enterprise

The same hosted PBX platform serves both ends of the market. A two-person office in Perth and a national organisation with 200 staff across five states both run on the same Simtex infrastructure. For multi-site businesses, extensions at different locations operate as a single system — internal calls between offices are free, and transfers between sites work the same as transferring between desks. If you already have a PBX system on-site, Simtex SIP trunks connect it to the Simtex network without replacing your existing hardware.

• Single-extension plans available — start small, scale without contract penalties
• No minimum terms on month-to-month plans
• Add extensions instantly — new staff member today, new extension today
• Multi-site ready — one hosted PBX system for all your Australian offices, with optional 1300 or 1800 numbers for inbound routing across locations
• Work-from-home compatible — remote workers use the same extension as if they were in the office, via softphone or a provisioned handset at home

If you're replacing an ageing on-premises PABX, migrating to a hosted phone system typically reduces ongoing telephony costs while adding features that older hardware can't support — call recording, IVR designer, voicemail to email, and a web-based admin portal that doesn't require a technician to make changes.
