# Yeastar P-Series review: pricing, pros and cons

> Saaskly verdict: **3.0/5**. SMB PBX sold as appliance, software or cloud edition through channel partners: solid and well-supported in the UK, but an infrastructure product rather than a cloud-native platform.

## Pros and cons

**Pros**

- Genuine on-prem appliance option plus software and cloud editions
- All-inclusive feature plans: no per-user add-ons
- Strong UK channel and enhanced 999 handling

**Cons**

- Needs your own (or a partner’s) infrastructure, not cloud-native (our direct experience)
- No public cloud or software-edition pricing
- Partner-only purchasing

## Pricing

Month-to-month price first (what you pay without committing), then the annual-commit rate.

- **P550 Enterprise plan**: $399/yr on an annual commitment; month-to-month price not published
  - Includes: Per PBX per year (~$33/mo equivalent); no monthly term
- **P550 appliance (UK reseller)**: £1,017 one-time
  - Includes: Up to ~50 users; P560 ~£1,416

Minimum commitment: **$399** ($399/yr for the entry licence).

## Specification

| Attribute | Value |
| --- | --- |
| Month-to-month (entry plan) | Annual only |
| Annual commit, per month | $399/yr |
| Minimum commitment* | $399 |
| Min seats | 1 |
| Deployment | Hybrid |
| Sales model | Partner only |
| Public API | Yes |
| MCP server | No |
| Emergency 911/999/112 | Yes |
| Integrations | Microsoft Teams (Call2Teams), Zoho, HubSpot, Salesforce, Zendesk, Freshdesk, WhatsApp |
| Commitment for annual rate (months) | 12 |

*How we calculate minimum commitment. Headline per-user prices hide the real cost of trying a platform. Total cost of ownership is licence × seats × term, plus usage, add-ons, setup fees and any early-exit charges. Our "minimum commitment" figure is the floor of that: the entry plan's committed rate × the minimum seats the vendor will sell × the months you must commit to (one month at the month-to-month rate where there is no commitment; the licence price where it is sold per year). It deliberately excludes usage, add-ons and prerequisite licences, so your real first bill will be higher, but never lower than this. For Teams Phone the excluded prerequisites are the Microsoft 365 and Teams licences.

## Our review

Yeastar's P-Series comes in three editions: a physical appliance (P520–P570, roughly 20 to 300 users), a Software Edition you run on your own VM or cloud, and a Cloud Edition hosted by Yeastar or a partner. All are licensed per PBX via all-inclusive Standard/Enterprise/Ultimate plans rather than per-user add-ons. It has good Teams presence sync (via Call2Teams), CRM integrations, an Open API with webhooks, Linkus clients and enhanced 999 handling, and a strong UK channel.

Only the appliance plan price is public (P550 Enterprise about $33 a month billed annually); cloud and software pricing is partner-portal only. We have run Yeastar in production: like 3CX, it needs infrastructure behind it rather than being a properly cloud-native platform, which is the main reason it sits mid-table. Trustpilot has no usable data.
