Yeastar Cloud PBX review

Yeastar Cloud PBX is a business phone and unified communications system for companies and, especially, service providers that host or sell communications to their own customers. It brings calling, video, chat, messaging, contact center features, and AI tools into one system.

You can run it on infrastructure you manage, on a preferred public cloud, or on Yeastar-hosted infrastructure. That gives providers more deployment choice than a service tied to a single hosting model, but it also means the hosting and administration setup may differ from one customer to another.

The Linkus clients are listed for Android, iOS, Windows, macOS, and web. Yeastar also lists auto provisioning support for more than 220 SIP trunk providers and 550 IP phone models. Those figures suggest broad compatibility on paper, but the published materials do not specify which integrations or provisioning features are available on each plan.

The clearest selling point is the breadth of the system. Yeastar lists voice queues, wallboards, live chat, WhatsApp, and SMS for its contact center, with no per-agent fees. That pricing model may suit providers serving customers whose agent counts change, although the platform’s base and add-on costs are not published.

AI features include voice agents, transcription, and summaries, with integration to CRM and other tools. The published materials do not name the supported CRMs or explain which AI features are included in each plan, so buyers should confirm those details before comparing it with a separate contact center or AI service.

Deployment choice is another practical advantage: a provider can use Yeastar hosting or deploy on customer infrastructure or a preferred cloud. Linkus clients cover the major desktop and mobile platforms, and the listed auto provisioning catalog spans 220-plus SIP trunk providers and 550-plus IP phone models.

One Reddit commenter using the cloud service with several customers said it was working well and described the desktop client as responsive. That is one user’s report, not a performance benchmark.

Price transparency is the main reason to pause. The published pricing information lists a 30-day trial and two plans, Enterprise and Ultimate, but publishes no monthly or annual prices. It also leaves billing terms, overage costs, and prices for expansions and AI usage unpublished. We cannot tell from the available information what a typical deployment will cost.

The listed plans start at 5 and go to 500 extensions per PBX instance, with expansion available. Each lists 500 recording minutes, also expandable, and expandable concurrent calls. Those are real caps to check against expected usage; expansion prices are not published. AI transcription and AI Receptionist use on-demand minute packs or monthly rolling plans, but their prices are also unavailable.

There are operational caveats in user discussions, though they may not reflect current versions. A commenter on r/MSP reported permissioning issues for customers managing their own extensions. Another user said a settings change once required a reboot and reported an unhelpful support response. A separate report about self-hosting and SIP trunk configuration describes call drops, but does not establish a general product fault.

Yeastar’s starting price is not published, and the published pricing information lists no monthly or annual rates for either plan. Enterprise and Ultimate are both priced per PBX instance; the available details list the same limits for each: 5–500 extensions, expandable concurrent calls, and 500 recording minutes, with expansions available. A price jump between tiers—and what separates them—is not published, so there’s no reliable tier comparison to make from these details.

There’s a 30-day free trial, but no free plan. Add-on prices are also not published for extension expansion, extra recording minutes, high availability, AI transcription, AI receptionist, or YCM White Label. Overage costs and billing terms are not specified. That leaves the total bill unclear, particularly if you need more capacity or AI minutes. Before committing, ask for a quote that spells out instance costs, add-ons, overages, and whether the quote is monthly or annual.

Yeastar offers hosted, customer-infrastructure, and preferred-cloud deployment, so the move depends partly on which setup you choose. But the published material does not publish migration steps, migration services, data-export formats, or details on moving numbers, call settings, recordings, and contacts. Get those answers in writing before you plan a cutover; deployment choice alone does not confirm how portable your data or configuration will be.

Yeastar lists auto provisioning for 220+ SIP trunk providers and 550+ IP phone models, which may help with device and carrier compatibility, but it does not guarantee that your current setup will transfer unchanged. Ask who handles configuration, what data can be exported, and what happens if you leave. We don’t have Reddit posts or comments in the published material, so we can’t responsibly report user-reported reasons for leaving. For now, the clearest documented reason to hesitate is commercial: plan prices, add-on prices, and overages are not published.
