    SIP Trunks

    Connect your on-premise telephony to a future-proof solution and make calls over any network.

    A flexible voice calling solution delivered over the internet.

    SIP Trunks allows your business to connect to the Public Switched Telephone Network (PSTN) to access high-definition voice services over an active internet connection. It provides an IP-based connection, allowing you to make calls from existing phone systems.

    Enjoy the freedom of using any internet provider without requiring a dedicated IP network. Our solution is highly scalable, allowing you to add more channels quickly and easily as your needs change.

    Our service is highly secure and resilient with built-in redundancies, all hosted in the Vocus cloud. Tailor a solution that’s fit for your business—choose from a range of calling plans, devices, and add-on services for one simple monthly cost.

    Case study: Amnesty International Australia

    Value and outcomes are important to all industries, but probably none as much as the not-for-profit sector. Most need to punch above their weight to deliver outcomes with limited assets. This was the case with Amnesty International Australia, an organisation that’s needed to evolve rapidly to meet the demands of diverse stakeholders, who want a strong presence in the digital world.

    “Walk around our office and you’ll find nearly everyone engaging in high-definition video conferencing from their desks. They’re working with stakeholders, suppliers, and colleagues who are in other states or working from home."

    Pete Thomas, Chief Operating Officer
    Amnesty International Australia
