Business VoIP, Internet & Cloud Collaboration

All IT Services delivers managed VoIP phone systems, high-speed business internet, and unified collaboration platforms — designed for Australian businesses that need reliable, scalable communications without the complexity.
let's do this!

Business VoIP & Phone Systems

VoIP (Voice over Internet Protocol) replaces traditional copper phone lines with internet-based calling, giving businesses lower call costs, greater flexibility, and enterprise-grade features — without the expensive on-premise hardware that legacy PBX systems require.

For growing Australian businesses, VoIP is now the standard for voice communications. Unlike traditional phone systems that lock you into fixed lines and rigid contracts, a modern VoIP platform scales with your team, works from any location, and integrates directly with your existing business tools like CRMs, helpdesks, and Microsoft 365.

3CX Certified Partner

All IT Services is a certified 3CX deployment partner. 3CX is a software-based PBX platform that runs in the cloud or on-premise, providing a full unified communications suite — voice, video conferencing, live chat, and SMS — within a single licence. We handle the complete lifecycle: solution design, deployment, number porting, user training, and ongoing management.

SIP Trunking & Hosted PBX

Whether you need SIP trunking to connect an existing PBX to the internet, or a fully hosted cloud PBX that eliminates on-site hardware entirely, All IT Services designs the right architecture for your business. Our hosted PBX solutions support HD voice using the G.722 codec, ensuring crystal-clear call quality even over standard business internet connections.

Why Businesses Switch to VoIP

  • Cost savings of 40–60% compared to traditional phone systems, with predictable per-user monthly pricing
  • Instant scalability — add or remove extensions in minutes, from 5 users to 500+, with no new hardware
  • Work-from-anywhere flexibility with softphones, mobile apps, and browser-based calling for remote and hybrid teams
  • Enterprise features included — auto-attendants, call queuing, IVR menus, call recording, voicemail-to-email, and real-time analytics
  • CRM and helpdesk integration — connect your phone system to tools like HubSpot, Salesforce, and Freshdesk for screen pops and automatic call logging

Business Internet & Connectivity

Reliable business internet is the backbone of modern operations — from VoIP calls and cloud applications to video conferencing and real-time collaboration. All IT Services provides managed internet solutions with SLA-backed uptime, proactive monitoring, and automatic failover to keep your business connected.

Unlike residential-grade connections, business internet from All IT Services includes guaranteed symmetric speeds, priority support, and Quality of Service (QoS) configuration that ensures latency-sensitive applications like VoIP and video always get the bandwidth they need.

NBN Enterprise Ethernet

For businesses that need guaranteed bandwidth and uptime, NBN Enterprise Ethernet delivers symmetric speeds with carrier-grade SLAs. All IT Services provisions, configures, and manages your Enterprise Ethernet connection end-to-end — including router configuration, firewall integration, and ongoing performance monitoring.

SD-WAN for Multi-Site Businesses

SD-WAN (Software-Defined Wide Area Network) intelligently routes traffic across multiple internet connections, maximising performance and reliability for businesses with two or more locations. SD-WAN replaces expensive MPLS networks with a more flexible, cost-effective architecture that dynamically prioritises critical traffic like VoIP and cloud applications.

4G/5G Failover & Redundancy

No single internet connection is 100% reliable. All IT Services deploys automatic 4G and 5G failover solutions that detect an outage and switch your traffic to a mobile backup link within seconds — ensuring your VoIP phones stay online, your cloud apps remain accessible, and your team stays productive even during an ISP outage.

Dedicated Fibre

For bandwidth-intensive operations — data-heavy applications, large file transfers, or businesses with 50+ concurrent VoIP users — dedicated fibre provides uncontended, symmetric connectivity direct to your premises with SLA guarantees on speed, latency, and jitter.

Microsoft Teams Phone & Collaboration

Microsoft Teams Phone transforms your Microsoft 365 environment into a complete cloud-based phone system — replacing legacy PBX hardware and standalone VoIP platforms with a single, integrated communications solution built directly into Microsoft Teams.

All IT Services deploys and manages Microsoft Teams Phone solutions purpose-built for Australian businesses. From number porting and call routing to auto attendants and call queues, we handle the full deployment so your team can make and receive calls from anywhere — on any device — without the complexity of managing separate phone infrastructure.

Teams Phone System Setup & Number Porting

Transitioning to Microsoft Teams Phone starts with getting your numbers right. All IT Services manages the entire porting process — moving your existing business numbers from legacy carriers into Teams Calling Plans or Direct Routing. We configure call routing, dial plans, emergency calling (000) compliance, and voicemail policies so your phone system is fully operational from day one.

Auto Attendants & Call Queues

Replace your old IVR menus and reception workflows with Teams Auto Attendants and Call Queues. All IT Services designs and configures intelligent call flows that route callers to the right person or department — with business hours scheduling, overflow handling, and on-hold messaging — all managed directly within the Teams admin centre.

Teams Calling on Any Device

Whether your team uses desk phones, headsets, mobile devices, or Teams-certified meeting room hardware, All IT Services ensures seamless calling across every endpoint. We provision and configure certified SIP devices, deploy the Teams mobile app for on-the-go calling, and integrate with meeting room systems so every workspace is phone-ready.

Direct Routing & SBC Integration

For businesses that need to retain existing SIP trunk providers or require advanced call routing, All IT Services deploys Direct Routing with certified Session Border Controllers (SBCs). This gives you the flexibility of Teams Phone with the carrier and routing control your business demands — including multi-site configurations and hybrid deployments.

Ongoing Management & Licence Optimisation

Microsoft 365 and Teams Phone licensing is complex — Calling Plans vs. Operator Connect vs. Direct Routing, domestic vs. international add-ons, and per-user costs add up quickly. All IT Services manages your licence allocation, monitors call quality and usage analytics, handles onboarding and offboarding, and provides priority support for any telephony issues.

Common Questions

Frequently Asked Questions About Business VoIP & Internet

What is VoIP and how does it work for businesses?
VoIP (Voice over Internet Protocol) transmits voice calls over your internet connection instead of traditional copper phone lines. For businesses, this means lower call costs, easy scalability, and access to enterprise features like auto-attendants, call recording, and CRM integration — all without expensive on-premise hardware.
How much does a business VoIP system cost in Australia?
Business VoIP systems in Australia typically cost between $25 and $60 per user per month for a hosted solution, depending on features and call inclusions. This compares favourably to traditional PBX systems, which require significant upfront hardware investment plus ongoing maintenance and carrier contracts.
What is 3CX and why does All IT Services recommend it?
3CX is a software-based PBX platform that can run on-premise or in the cloud. All IT Services is a certified 3CX partner, handling deployment, configuration, and ongoing support. 3CX includes video conferencing, live chat, call centre features, and mobile apps — all within a single licence, making it one of the most cost-effective unified communications platforms for SMEs.
Can I keep my existing phone numbers when switching to VoIP?
Yes. Number porting allows you to transfer your existing business phone numbers to a VoIP system with no disruption. All IT Services manages the entire porting process with your current carrier to ensure zero downtime during the transition.
What internet speed do I need for VoIP?
Each concurrent VoIP call requires approximately 100 Kbps of bandwidth. For an office with 10 simultaneous calls, you would need at least 1 Mbps dedicated to voice traffic. All IT Services assesses your current connection and can provision dedicated business internet with Quality of Service (QoS) configuration to prioritise voice traffic and prevent call dropouts.
What is SD-WAN and does my business need it?
SD-WAN (Software-Defined Wide Area Network) intelligently routes traffic across multiple internet connections to maximise performance and reliability. If your business operates across multiple sites, relies on cloud applications, or needs guaranteed uptime for VoIP and video conferencing, SD-WAN can significantly improve your experience while often reducing costs compared to traditional MPLS networks.
How long does it take to switch to a VoIP phone system?
A typical VoIP deployment for a small-to-medium business takes 2 to 4 weeks from initial assessment to go-live. This includes network assessment, system configuration, number porting, hardware provisioning (if required), user training, and a parallel running period to ensure a smooth transition with zero disruption to your business.
