Yeastar Cloud PBX: The Complete Guide to Features, Pricing & Setup

The Complete Guide Yeastar Cloud PBX to Features, Pricing & Setup

The business phone system market has shifted dramatically over the past few years. Traditional on-premise PBX hardware is giving way to cloud-based solutions that offer more flexibility, lower costs, and the ability to support hybrid and remote workforces. Among the cloud PBX providers gaining serious traction globally, Yeastar stands out for a reason that matters to businesses of all sizes: deployment flexibility.

Unlike most cloud PBX providers that force you into a single deployment model, Yeastar’s P-Series Phone System lets you choose between cloud, software (self-hosted), and physical appliance editions — all running the same platform with the same features. That kind of choice is rare in the market, and it’s why over 450,000 businesses worldwide now run on Yeastar.

In this guide, we’ll cover everything you need to know about Yeastar Cloud PBX: what it does, how it compares to alternatives, what the different plans cost, and how to decide if it’s the right fit for your business.

What Is Yeastar Cloud PBX?

Yeastar Cloud PBX is the cloud-hosted edition of the Yeastar P-Series Phone System. It’s a full unified communications platform that handles:

• Voice calling — Inbound and outbound calls over SIP trunks, with support for local, national, and international numbers
• Video conferencing — Built-in video meetings without needing a separate platform
• Team messaging — Internal chat for quick team communication
• Contact centre features — Call queues, IVR menus, wallboards, agent monitoring, and call recording
• CRM and business tool integration — Native integrations with Salesforce, HubSpot, Zoho, Zendesk, Microsoft Teams, and more
• Mobile and desktop apps — The Linkus UC Client provides a unified experience across phones, tablets, and computers

The “Cloud PBX” part means Yeastar (or your service provider) hosts the system in the cloud. You don’t need any on-site hardware beyond IP phones or softphones. Everything is managed through a web-based portal, and your team can connect from anywhere with an internet connection.

Yeastar P-Series: Understanding the Platform

The P-Series is Yeastar’s flagship product line. It replaced the older S-Series and has become one of the most popular PBX platforms for small and mid-sized businesses globally.

Three Deployment Options

One of Yeastar’s biggest differentiators is that the P-Series runs on three different deployment models:

1. Cloud Edition (PCE)

• Hosted in the cloud by Yeastar or your service provider
• Zero on-site hardware needed
• Automatic updates and maintenance
• Best for: Businesses that want a fully managed, zero-maintenance phone system

2. Software Edition (PSE)

• Self-hosted on your own server or virtual machine (VMware, Hyper-V, or cloud platforms like AWS, Azure, Google Cloud)
• Full control over your deployment environment
• Best for: Businesses with IT teams that want control over hosting and data location

3. Appliance Edition

• Physical hardware appliance installed on-site
• Available in multiple models: P520, P550, P560, P570 (scaling from small offices to large enterprises)
• Best for: Businesses that prefer on-premise infrastructure or have limited internet bandwidth

The critical point is that all three editions run the same P-Series platform. Features, management interface, and user experience are identical regardless of deployment model. This means you can start with a cloud deployment and migrate to on-premise later (or vice versa) without retraining your team or losing configuration.

Key Features of Yeastar Cloud PBX

Linkus UC Clients

Linkus is Yeastar’s unified communications app, available on:

• Web browser — No installation needed, accessible from any device
• Desktop — Windows and macOS applications
• Mobile — iOS and Android apps

With Linkus, every employee gets a complete phone system in their pocket. They can make and receive calls on their business number, join video conferences, chat with colleagues, access voicemail, and view call history — all from a single app.

Key Linkus features:

• Call flip — Seamlessly transfer an active call from your desk phone to your mobile (or vice versa) with one tap
• Presence status — See which colleagues are available, busy, on a call, or away
• Unified contacts — All contacts from PBX phonebooks, CRM, and personal contacts in one searchable directory
• Voicemail to text — Read voicemail messages instead of listening to them

Call Operator Panel

The Operator Panel is a visual call management tool designed for receptionists and operators. It provides:

• A real-time view of all extensions, their status, and active calls
• Drag-and-drop call handling — transfer calls by dragging them to the target extension
• Call parking, pickup, and monitoring from a single interface
• BLF (Busy Lamp Field) visibility across the entire organisation

This is one of Yeastar’s standout features. Most competing platforms either don’t offer an operator panel or charge extra for it. Yeastar includes it in the base platform.

Contact Centre and Queue Management

Yeastar Cloud PBX includes built-in contact centre features that many competitors charge extra for:

• Automatic Call Distribution (ACD) — Route incoming calls to the right agent based on skills, availability, or custom rules
• Call queues — Manage high call volumes with configurable queue strategies (ring all, round robin, least recent, fewest calls)
• IVR (Interactive Voice Response) — Multi-level, multi-language auto attendant menus that route callers to the right department
• Queue wallboards — Real-time display of queue status, wait times, and agent availability
• Agent coaching — Listen in, whisper to agents, or barge into calls for training and quality assurance
• Call recording — Record calls automatically or on-demand, with recordings stored and accessible through the management portal
• Queue callback — Let callers request a callback instead of waiting in the queue

CRM and Business Tool Integration

Yeastar integrates natively with a wide range of business tools:

The Microsoft Teams integration deserves special attention. Yeastar can serve as the PSTN gateway for Teams, meaning your employees can make and receive external phone calls directly within the Teams interface while Yeastar handles the SIP trunking and call routing. This is a cost-effective alternative to Microsoft’s own Calling Plans or Operator Connect.

Security Features

Yeastar takes security seriously with:

• SRTP and TLS encryption — Voice traffic and signalling are encrypted end-to-end
• Automatic and static defence — Built-in intrusion detection and prevention
• Global anti-hacking IP blocklist — Automatically blocks known malicious IPs
• Two-factor authentication (2FA) — Extra layer of security for admin and user accounts
• Password policy enforcement — Configurable password complexity requirements
• Allowed country IPs and codes — Restrict access to specific geographic regions
• Outbound call frequency restrictions — Prevent toll fraud by limiting outbound call rates

Administration and Management

The web-based management portal provides:

• Graphical dashboard — System health, call statistics, and resource usage at a glance
• Auto provisioning — Automatically configure supported IP phones when they connect to the network
• Bulk import/export — Add or modify extensions, contacts, and settings in bulk via CSV
• Role-based access control — Define what different users and administrators can see and do
• Event notifications — Get alerted about system events, failed logins, or performance issues
• Backup and restore — Scheduled automatic backups with one-click restore
• Remote management — Manage your PBX from anywhere through the web portal

Yeastar vs. 3CX: How Do They Compare?

This is the comparison most businesses want to see. Both are excellent platforms, but they serve different needs:

The bottom line: Yeastar is typically the better choice for small to mid-sized businesses prioritising cost efficiency and deployment flexibility. 3CX is typically stronger for businesses that need a mature ecosystem of third-party integrations and advanced contact centre features.

Many businesses (including ITelecoms) work with both platforms, which means we can help you evaluate which is the better fit for your specific needs.

How to Get Started with Yeastar Cloud PBX

Setting up Yeastar Cloud PBX is straightforward. Here’s the typical process:

Step 1: Assess Your Requirements

Before choosing a plan, determine:

• Number of extensions — How many employees need phone access?
• Concurrent call capacity — What’s your peak number of simultaneous calls?
• Feature requirements — Do you need CRM integration, contact centre features, Teams integration?
• Deployment preference — Cloud, self-hosted, or on-premise appliance?

Step 2: Choose Your Plan

Based on your requirements:

• Basic calling needs → Standard Plan (Appliance only)
• Unified communications + integrations → Enterprise Plan
• Full contact centre → Ultimate Plan

Step 3: Set Up SIP Trunking

Yeastar Cloud PBX connects to the public telephone network via SIP trunks. You’ll need to:

• Choose a SIP trunk provider (ITelecoms provides SIP trunking services that are fully compatible with Yeastar)
• Port your existing phone numbers or obtain new ones
• Configure the trunk connection in the Yeastar management portal

Step 4: Configure Your System

Through the web-based management portal:

• Create extensions for all users
• Set up IVR menus and call routing
• Configure call queues and ring groups
• Set up auto provisioning for IP phones
• Configure CRM integrations
• Set up voicemail, call recording, and other features

Step 5: Deploy Linkus to Your Team

Roll out the Linkus UC Client to all users:

• Web client: No installation — just share the URL
• Desktop app: Download from the Yeastar portal
• Mobile app: Download from the App Store or Google Play
• Link scanning: Users scan a QR code to connect automatically

Step 6: Test and Go Live

Before going live:

• Test inbound and outbound calling
• Verify call routing and IVR menus
• Test failover scenarios
• Confirm CRM integration is working
• Train key users on the Linkus client and any admin functions

Who Should Choose Yeastar Cloud PBX?

Yeastar Cloud PBX is an excellent fit for:

• Small and mid-sized businesses (5-500 employees) that need a professional phone system without enterprise pricing
• Multi-site businesses that need to connect multiple offices under one system
• Remote and hybrid teams that need to work from anywhere with the Linkus mobile app
• Businesses using Microsoft Teams that want PSTN calling through Teams without Microsoft’s expensive Calling Plans
• Growing companies that want to start in the cloud and potentially move to on-premise later (or vice versa) without changing platforms
• Cost-conscious organisations looking for 30-50% savings over per-user-per-month competitors like RingCentral or Zoom Phone

Frequently Asked Questions

Can I keep my existing phone numbers?

Yes. Number porting is standard practice. Your existing phone numbers can be transferred to work with Yeastar Cloud PBX through your SIP trunk provider. The process typically takes 1-2 weeks depending on your current provider.

Do I need to buy new phones?

Not necessarily. Yeastar supports a wide range of SIP phones from major manufacturers (Yealink, Fanvil, Snom, Grandstream, Poly, and others). If your current phones are SIP-compatible, they’ll likely work with Yeastar. Alternatively, you can use the Linkus softphone app on computers and mobile devices — no physical phone required.

How reliable is Yeastar Cloud PBX?

Yeastar Cloud PBX includes built-in redundancy and disaster recovery options (on the Ultimate plan). The platform is backed by an SLA, and you can configure hot standby for automatic failover. Your reliability also depends on your internet connection — a dedicated business-grade internet connection with QoS (Quality of Service) configured for voice traffic is recommended.

Can I integrate Yeastar with Microsoft Teams?

Yes. Yeastar’s Microsoft Teams integration allows your employees to make and receive PSTN calls directly within the Teams interface. Yeastar handles the SIP trunking and call routing, while Teams provides the user interface. This is available on the Enterprise and Ultimate plans.

How does Yeastar compare on price?

Yeastar is typically 30-50% less expensive than per-user-per-month platforms like RingCentral, 8×8, or Zoom Phone at equivalent feature levels. The exact cost depends on your number of extensions, chosen plan, and any add-on services. Contact ITelecoms for a customised quote.

Is Yeastar secure?

Yes. Yeastar includes enterprise-grade security features including TLS/SRTP encryption, automatic intrusion detection, two-factor authentication, IP access control, and anti-fraud call rate limiting. For businesses with strict compliance requirements, the Software and Appliance editions allow you to host the system within your own infrastructure.
