Operator Connect in Australia

Dear Peter Ternouth,

To ensure I understand your request correctly and to support you as effectively as possible, I need more specific information from you:

• Which Partner Service Providers have you engaged?

For a small business, I suggest starting with these options:

• Aussie Broadband Aussie Broadband Operator Connect offers a per-user, per-month service with Australian number portability, new numbers, calling-plan options, auto attendants, and call queues. Its published service appears suitable for businesses that want a locally supported and scalable deployment, although you should confirm its current minimum-seat requirement directly.
• Access4 through an Australian Microsoft partner or managed service provider Access4 Operator Connect specifically describes flexible PAYG and included-call licensing, including small licence models for small and medium businesses. Access4 is channel-focused, so you would normally purchase the service through one of its partners rather than directly from Access4.

You can also use the official Microsoft Operator Directory and filter for Calling and Australia. The directory lists certified operators, but it does not guarantee that every operator accepts very small deployments. Operator Directory

If Operator Connect providers still will not engage, consider Microsoft Teams Calling Plans. This is generally the simplest PSTN option because Microsoft acts as the carrier and no Session Border Controller is required. Availability, Australian telephone-number types, porting, and licensing should be checked against the current country availability page.

Here are some references:

I hope the information shared helps point you in the right direction.
