What this can include
Use the Yeastar features your team actually needs.
Yeastar can support Yealink desk phones, Linkus softphones, mobile users, queues, reporting and Microsoft Teams integration. The design work is deciding which interface and feature set each role actually needs.
Build queues and routing properly
Design reception, departments, overflow, opening hours and voicemail before users go live.
Use Linkus clients
Give supported users desktop, web and mobile calling without creating a separate phone identity.
Pair with the right SIP service
Size trunks and resilience alongside the PBX so the whole voice path is engineered together.
Integrate Teams without making it the PBX
For supported P-Series deployments, selected users can work from Microsoft Teams while Yeastar remains the phone-system core and Yealink endpoints stay in the mix.
Add structured customer-service workflows
Use supported inbound queues, agent and supervisor tools, wallboards, reporting, outbound workflows and digital messaging where customer-facing teams need more than standard PBX call handling.
Designed around the workplace
Use P-Series as the communications core, then choose the right interface for each user.
Yeastar can bring PBX call handling, Linkus clients, Yealink endpoints, integrations and contact centre capabilities into one platform. The design decision is which of those tools each role genuinely needs.

CRM integration
Connect business calls with the customer record.
Yeastar P-Series supports ready-made CRM integrations and custom REST API integrations, so the phone system can sit closer to the tools your sales and service teams already use.
Ready-made integrations for widely used CRMs.
Current P-Series integrations include HubSpot, Salesforce, Zoho CRM, Microsoft Dynamics 365, Odoo and Bitrix24. The exact features depend on the CRM, P-Series edition and software version, so we confirm compatibility as part of the system design.

Call from the customer record
Let supported users start calls from numbers inside the CRM rather than re-keying them into a handset or app.
See who is calling
Open the matching CRM contact when a recognised customer calls, helping users get useful context before or during the conversation.
Keep activity closer to the CRM
Supported integrations can synchronise call activity and customer interaction records so teams spend less time entering the same information twice.
Connect other REST API systems
If your CRM is not one of the ready-made options, Yeastar also supports custom CRM integration templates for compatible systems with a REST API.

Is it right for you?
Where this option works best.
Yeastar is compelling when you want a feature-rich PBX with deployment flexibility, practical administration and room to add contact centre capability for customer-facing teams.
Choose this when
You want strong PBX call handling, Linkus apps, deployment choice, Yealink endpoints, SIP trunking and optional Microsoft Teams integration while keeping Yeastar as the phone-system core.
Consider another route when
If your only requirement is basic calling with no meaningful PBX workflow, a simpler hosted option may deserve comparison. If Teams is important, we can still keep Yeastar as the PBX and integrate Teams for the users who need it.
We can help you choose.
Tell us what you have today and what needs to improve. We’ll explain the options and recommend the setup that best fits your business.
Plan the change carefully.
We plan number porting, call flows, connectivity and user training before the system goes live.

Common questions
Frequently asked questions.
Short answers to the questions we are most often asked about this type of system.
What is Yeastar P-Series?
P-Series is Yeastar's business communications platform, available in different deployment models and supporting PBX features, apps, call handling and integrations.
Can Yeastar work with SIP trunks?
Yes. Yeastar PBX systems can connect to supported SIP trunk services. Trunk compatibility and configuration should be validated as part of deployment.
Does Yeastar support remote workers?
Supported Linkus clients can allow users to make and receive business calls away from a desk phone, subject to system configuration and licensing.
Can Yeastar integrate with Microsoft Teams?
Yes. Supported Yeastar P-Series deployments can integrate Linkus with Microsoft Teams so users can work from Teams while the Yeastar PBX continues to provide the underlying phone-system features. Exact licensing and version requirements should be checked for the chosen integration method.
Do you sell Microsoft Calling Plans?
No. Zero’s core proposition is Yeastar PBX systems, Yealink endpoints and SIP connectivity. Microsoft Teams is an optional integration layer where it suits the user workflow.
Can Yeastar integrate with CRM systems?
Yes. Current P-Series ready-made CRM integrations include HubSpot, Salesforce, Zoho CRM, Microsoft Dynamics 365, Odoo and Bitrix24. Supported features can include click-to-call, caller pop-ups, contact synchronisation and call-record synchronisation. Custom CRM templates are also available for compatible REST API systems.
