Frequently Asked Questions

Which plan should I choose?

Each company has unique needs. While many users decide on a plan based on users and feature requirements, these are the general guidelines we had in mind:

PBX Appliance Models:

P550: for companies with less than 50 users and 25 concurrent calls

P560: for companies with 50-200 users or 30-60 concurrent calls

P570: for companies with 200-300 users or 60-120 concurrent calls

Feature Plans:

Basic Plan: for companies with basic business communications needs.

Standard Plan: for companies with remote/mobile workers and need to stay connected anywhere anytime.

Enterprise Plan: for companies with sophisticated remote working, call center, and system integration demands.

Ultimate Plan: for companies with the need to bring all communications stacks in one integrated system, regardless of locations.

Note: before you subscribe a standard or above plan in this page, please make sure you have a P-Series appliance in place.

If you need a PBX appliance/software PBX/Cloud PBX or need any recommendation on the solution, feel free to send us a message for expert help.

Is there a free trial?

Yes! For each P-Series PBX appliance, users can log into their PBX’s Management Portal > Plan to enable a 30-day free trial (each PBX can enable the free trial for only once).

For users who have not purchased a P-Series appliance yet or prefer to use a cloud or software PBX, it’s recommended to try out the features with our P-Series Cloud Edition 30-day free trial. All three editions of Yeastar P-Series PBX System (Appliance, Cloud, Software) share the same feature scope.

How do I upgrade my plan?

To upgrade the plan for your P-Series appliance, simply click the “upgrade” button on this page or upgrade in your PBX’s management portal. You can also contact your device provider for help.

You can upgrade your plan at any time and only the prorated difference will be charged.

Does the listing price include VAT?

No. All price listed in this page are exclusive of VAT and is for P-Series Appliance Edition only. For the pricing of the P-Series Cloud and Software Edition, please contact us.

Which payment methods are accepted?

We accept payment by PayPal, by credit card (VISA / MasterCard / AMERICAN EXPRESS / Discover Card), and by offline payment (with payment instruction via email).

What if I decide to downgrade or cancel?

You can choose not to renew your subscription or subscribe to a lower plan while your current plan is still valid. The lower plan will take effects automatically when your higher plan expires.
