One platform for calls, video, messaging, and collaboration. eComms designs and manages unified communications environments for businesses of all sizes, from a five-person office to a 500-seat enterprise.
Unified communications converges phone calls, video conferencing, instant messaging, voicemail, and file sharing into a single platform on any device.
Staff communicate the same way whether in the office, working from home, or between client sites, reducing missed calls and delays.
Our Melbourne-based engineers design, deploy, and manage UC across Mitel, 3CX, and Microsoft Teams, whether replacing a PBX or migrating off ISDN.
Mitel is an enterprise-grade unified communications platform with a long track record in mid-market and large organisations. Strong for 50 to 2,000-plus user environments, MiVoice Business provides deep call control features, contact centre integration via MiContact Centre, and resilience options that keep phones working even during a network or server outage. For businesses that need proven enterprise telephony with full control over their environment, Mitel is the platform. eComms is an authorised Mitel partner and manages deployments of all sizes across Australia.
3CX is a modern, flexible, cloud-friendly platform well suited to growing businesses and mid-market organisations. It runs on the web, mobile, and desktop without desk handsets, integrates natively with most CRM platforms, and is priced per system rather than per user, which makes it significantly more cost-effective at scale than most cloud UC alternatives. For businesses that want simplicity and lower total cost without cutting corners on features, 3CX is the right fit. eComms is a certified 3CX partner in Australia.
For businesses already using Microsoft 365, Teams is a natural fit as a unified communications platform. eComms adds full PSTN calling to Microsoft Teams through Direct Routing, so staff can make and receive calls to any Australian or international number directly from the Teams interface without needing a separate phone system. If your business already lives in the Microsoft ecosystem, this approach consolidates collaboration and calling into one platform with one set of licences to manage.
Callation is a reporting and analytics platform that sits over your existing phone system, regardless of vendor, and surfaces call volume data, missed call tracking, agent performance metrics, and wallboard dashboards. For businesses that want to make informed decisions from their voice data, Callation provides the visibility that most phone systems do not deliver natively. It works alongside Mitel, 3CX, and most major PBX platforms.
For businesses that want their phone system running in a private cloud environment rather than on-site hardware, eComms offers hosted voice infrastructure on AWS or iLand. The system runs in an Australian data centre, managed by eComms, with the resilience and scalability of cloud infrastructure and the control of a dedicated environment. Automatic updates, managed backups, and no on-site server hardware to maintain.
Choosing between platforms depends on your organisation size, your existing Microsoft investment, and whether you prefer on-premise, hosted, or fully cloud-delivered. The table below gives a starting point. eComms can advise further based on your specific environment.
| Factor | Mitel MiVoice Business | 3CX | Microsoft Teams Phone |
|---|---|---|---|
| Best fit | 50 to 2,000+ users, enterprise features | 5 to 500 users, cloud or hosted | Microsoft 365 users, cloud-first |
| Deployment | On-premise or hosted | Cloud, hosted, or on-premise | Cloud (Microsoft-hosted) |
| Call features | Deep enterprise feature set | Full UC with CRM integrations | Teams-native calling via Direct Routing |
| Hardware phones | Mitel 6900 series IP phones | Yealink and compatible handsets | Teams-certified handsets |
| Managed by eComms | Yes, full managed service | Yes, full managed service | Yes, Direct Routing managed |
Multi-site businesses, including retail groups, professional services firms, and hospitality operators with three or more locations, need a consistent communications policy applied across every site. Without a single platform managing all locations, call routing, voicemail, and feature access vary unpredictably between sites. eComms applies the same phone system policy across every location and manages it from one console, with changes implemented once rather than repeated at every site individually.
Hybrid and remote-first businesses need a phone system that performs the same whether staff are sitting at a desk, working from home, or visiting a client. Mitel MiCollab and 3CX both deliver the full phone system experience on any device, including mobile apps, desktop clients, and browser-based calling, so there is no gap between what a staff member can do in the office versus from home.
Businesses migrating off legacy ISDN or PSTN lines face a transition deadline imposed by Telstra’s network retirement schedule. eComms manages the full migration including number porting, system deployment, carrier cutover, and user training, so the business goes from an aging copper line setup to a modern VoIP environment without a disruption to daily operations.
Thousands of Businesses Across Australia Trust eComms to Keep Them Connected
“Overall we have been very happy with the solution. One feature that has proved very useful is the Scheduled Camp Numbers. We are able to publish a fixed phone number to parents and then simply redirect it to different staff mobiles according to a programmed schedule as needed.”

Answers to common questions about our managed phone systems, connectivity solutions, carrier network, and ongoing support services.
Unified communications, or UC, is the integration of phone calls, video conferencing, instant messaging, voicemail, and file sharing into a single platform. Rather than staff switching between a desk phone, a separate video tool, and a messaging app, everything runs from one system accessible on any device. For Australian businesses, the practical benefit is that staff communicate the same way whether they are in the office, at home, or between sites, which reduces missed calls, delays, and the cost of managing multiple separate tools.
Mitel is an enterprise-grade UC platform with a long track record in larger organisations, deep feature depth, and strong resilience options for businesses that need guaranteed uptime and carrier-grade call control. 3CX is a modern, flexible platform that works well for growing businesses and cloud-first environments, with a lower total cost and easier self-management for IT teams that want more control. eComms is an authorised partner for both and recommends based on your size, budget, and how much you want to manage internally versus outsource.
Yes. Microsoft Teams can function as a full business phone system when combined with a Direct Routing solution from a provider like eComms. Direct Routing connects Teams to the public telephone network so staff can make and receive calls to any Australian or international number, not just other Teams users. If your business already uses Microsoft 365, this approach consolidates your collaboration and calling into one platform. eComms manages the SIP connectivity, number porting, and ongoing support as a managed service.
UCaaS, or Unified Communications as a Service, is a cloud-delivered UC platform where the phone system software is hosted and maintained by the provider rather than on hardware at your premises. A traditional PBX is a physical appliance you own and manage on-site. UCaaS means you pay a monthly per-user or per-system fee, receive automatic updates, and scale up or down without purchasing additional hardware. Both options are available through eComms depending on your preference, existing infrastructure, and compliance requirements.
Whether you are replacing an aging PBX, migrating off ISDN before your exchange is switched off, or choosing between platforms for the first time, our Melbourne team can walk you through the options. The assessment is free and starts with your environment, not a product pitch.
