Most telcos sell plans. upstream builds communication systems around how your business actually operates, VoIP, NBN, mobile, and unified collaboration tools tailored to your team size, industry, and day-to-day workflow, not a one-size-fits-all package.

Whether you're a small team outgrowing a basic phone line or a growing business managing multiple sites, we design solutions that keep everyone connected without the lock-in contracts or hidden costs that come with many providers.

VoIP That Scales As You Do

Traditional phone systems weren't built for how modern teams work. Our hosted VoIP supports multiple simultaneous calls, conference calling, and remote access to keep your team connected whether they're in the office or working from anywhere, while the system scales as call volumes grow or shrink without hardware refits or technician visits.

NBN Internet Without the Lock-In

Slow, unreliable internet costs businesses real time and money. We provide high-speed NBN connections built for business use, backed by a straightforward approach: no lock-in contracts, meaning you're never stuck paying for a service that no longer fits. For businesses running cloud tools, VoIP, and daily online transactions, reliable internet isn't optional; it's operational infrastructure.

Mobile Plans That Move With Your Team

Long device repayments and rigid contracts don't suit every business. Our SIM-only mobile plans offer unlimited calls and texts within Australia on a month-to-month basis, giving you the flexibility to scale your mobile fleet up or down as your team changes, without being locked into 12- or 24-month terms.

One Platform for Calls and Collaboration

For businesses already using Microsoft 365, Teams Connect brings calling, chat, video meetings, and collaboration into a single platform, removing the need to juggle separate tools for voice and messaging, a practical option for teams wanting fewer logins and one less system to manage.

Support That Doesn't Stop at Installation

Getting connected is the easy part. What matters more is what happens when something goes wrong or your needs change. Our team provides ongoing support, troubleshooting, and system updates, so your communication tools keep working as your business grows, not just on the day everything was installed.
