What Is Yeastar P-Series? An Australian Buyer’s Guide

If 3CX is the business phone system everyone’s heard of, Yeastar is the one the industry quietly rates. So what is Yeastar? Yeastar is a global phone-system maker whose flagship P-Series is a full unified communications platform – calls, video, messaging, call centre tools – that you can run three different ways: as a physical appliance in your office, as software, or in the cloud. That deployment flexibility is its signature move.

The P-Series family

• P550 / P560 / P570 appliances: compact hardware PBXs sized for roughly 50, 100 and 300 users respectively – mount one in the comms cabinet and your phone system lives on-site, under your roof.
• Software edition: the same platform installed on your own server or virtual machine.
• Cloud edition: Yeastar hosted, nothing on-site.

All three run the same feature set, managed through the same clean web console – covered in depth on our Yeastar P-Series overview.

What you get in the box

• Linkus UC clients – web, desktop and mobile apps so every extension works from anywhere.
• Video conferencing – built-in meetings with screen sharing, no extra licences.
• Omnichannel messaging – SMS and social messaging queued alongside calls on higher plans.
• Call centre tools – queues, wallboards, SLA monitoring and reporting on the Enterprise plan.
• Remote working – secure remote extensions without VPN gymnastics, via Yeastar’s remote access.
• AI features – the P-Series has been steadily adding built-in AI (call summaries, transcription), and Tronic’s own AI voice agents integrate directly with Yeastar for full 24/7 AI answering.

Who suits Yeastar best?

1. Businesses that want the PBX on-site. Regional operations with patchy internet, sites with strict data policies, or owners who simply like owning the box – the appliance option is Yeastar’s ace.
2. Teams that want simple per-user plans. Yeastar’s licensing is straightforward user tiers – predictable and easy to budget.
3. Growing SMEs who want call-centre-grade features without enterprise pricing.

How does it stack against the obvious alternative? We wrote an honest 3CX vs Yeastar comparison – short version: 3CX wins on per-system licensing economics at scale, Yeastar wins on deployment flexibility, and both are excellent. Cost structure is covered in our Yeastar P-Series pricing guide.

Running Yeastar in Australia

You’ll want three things: the platform itself (appliance, software or cloud), SIP trunks carrying your numbers and calls, and someone accountable for setup and support. Tronic supplies all three – including porting your existing numbers and our free included basic support (requests under 15 minutes cost nothing, so nobody in your office needs to become the PBX person – details here).

Frequently asked questions

Is Yeastar any good?

Yes – Yeastar is a well-established global vendor and the P-Series is a mature, full-featured UC platform. It’s less famous than 3CX in Australia but widely deployed and well supported.

What is the difference between Yeastar P550, P560 and P570?

Capacity. They’re the appliance models sized for roughly 50, 100 and 300 users respectively, with the same software experience. Choose by user count and concurrent-call headroom.

Does Yeastar work with Yealink phones?

Yes – Yealink, Fanvil and other open-SIP handsets auto-provision with the P-Series. Existing handsets can usually be reused.

Can Yeastar integrate with AI?

Yes, twice over: the P-Series ships growing built-in AI features, and Tronic integrates full AI voice agents with Yeastar for 24/7 answering, triage and warm transfers.
