Our Verdict

Yeastar Cloud PBX is for teams that want a modern PBX or UC platform with SIP trunk choice, open integrations, centralized management, and partner-led deployment. You get cloud, software, or appliance phone infrastructure with Linkus apps, call-center tools, live chat, messaging, AI transcription, CRM and helpdesk integrations, and Teams options.

Avoid it if you need self-serve public user pricing. Test SIP trunks, call rules, AI limits, SMS or MMS, integrations, admin controls, and partner quote details before committing.

A good fit if you

  • SMBs and MSPs replacing legacy PBX with cloud-first UC.
  • Organizations that want SIP trunk flexibility and PBX-style administration.
  • Teams needing Linkus clients, queues, live chat/messaging, call-center features, and AI call tools.
  • Service providers or partners that value white-label and centralized management options.

Look elsewhere if you

  • Users that require public fixed per-user pricing before evaluation.
  • Teams that want the most polished mainstream UCaaS app with minimal VoIP knowledge.
  • Microsoft-first companies that can solve calling inside Teams Phone licensing.
  • Very small teams that only need basic phone numbers and simple setup.
Next step: write down the problem you need solved, check the pricing details, test one real workflow, then compare alternatives before you pay.

What Is Yeastar Cloud PBX?

Yeastar Cloud PBX is a cloud PBX and UCaaS platform that combines business calling, Linkus clients, video, messaging, call-center tools, omnichannel customer engagement, AI features, SIP trunk flexibility, and centralized management.

It fits users that want more PBX control than a simple cloud phone app, especially MSPs, service providers, and SMBs moving from legacy or self-managed phone systems.

Yeastar Cloud PBX Pros and Cons

Pros

  • Good PBX-to-cloud bridge — Yeastar keeps PBX control and SIP flexibility while adding cloud UC and modern clients.
  • 30-day official trial — The official Cloud PBX page promotes a 30-day free trial, giving users room to test real calling scenarios.
  • Broad built-in communications — Calling, video, messaging, queues, live chat, outbound tools, and Linkus clients cover more than dial tone.
  • Integration-friendly for service teams — Microsoft Teams, CRMs, helpdesks, PMS integrations, open APIs, and SIP trunk support are core reasons to evaluate it.
  • Partner/MSP fit — Centralized management and white-label readiness suit service providers and telecom partners.

Cons

  • No public fixed plan table captured — Official Cloud PBX pages does not publish exact plan prices in public page text.
  • VoIP knowledge still helps — SIP trunks, call routing, queues, SMS/MMS, and integrations require more setup than a basic phone app.
  • AI add-ons can affect cost — AI Receptionist, transcription, and summaries may depend on usage or add-on services.
  • Less mainstream market presence — Teams should test call quality, admin setup, integrations, support, and reseller fit before replacing a phone system.
  • Global carrier simplicity may vary — Users should verify PSTN/SIP trunk strategy in each country before migration.

Ask for a written quote that separates users, trunks, AI usage, contact-center features, support, and partner services.

What Users Say

GetApp 5.0/5 · 5 reviews

What works well

  • The small GetApp sample rates value, ease of use, and support very highly, with visible positive signs around call routing and Microsoft Teams/CRM workflows.
  • The product is most compelling when users want PBX control without staying fully on legacy hardware.

What gets frustrating

  • No stable complaint trend is visible from the small GetApp sample; the lower feature score versus value/support suggests users should still test feature depth.
  • Common practical risks are pricing opacity, hands-on VoIP setup, MMS/SMS or add-on limits, and carrier/integration validation.
MAQTOOB take: Yeastar fits users who still think like PBX administrators but want cloud deployment and modern UC. It is less attractive for teams that want self-serve public pricing and minimal setup.
