Frequently Asked Questions
What is Yeastar P-Series Cloud PBX?+-
An enterprise cloud phone system from Yeastar. Answer and place calls on your office number from any device — iOS, Android, PC, or a web browser — with no investment in on-site PBX hardware.
Where are call data and recordings stored, and how secure are they?+-
Hosted on the Bangkok / Huawei Bangkok region, so all data stays in Thailand in line with PDPA, and your organization sets its own data retention policy.
How is Cloud PBX different from a traditional IP PBX?+-
Cloud PBX needs no hardware installation, carries no equipment maintenance cost, updates itself automatically, and lets you add or remove users instantly — unlike an IP PBX, which requires investing in a server and maintaining it at the office.
Can we migrate an existing PBX, and how long does it take?+-
An on-premises PBX cannot be migrated directly. Our team installs and configures a completely new system, which takes at least about seven business days, and handles number porting and user training as well.
How is the service billed — are there hidden costs?+-
A monthly per-user fee (minimum five users) plus add-ons billed on actual usage, such as DID numbers and concurrent call channels. There are no hidden charges.
What is Call Concurrent?+-
It is the number of call connections that can be active at the same time — 1 CC per connection, at THB 80 per channel per month. Channels can be added or removed as needed, up to the number of extensions you have.
Can it connect to our CRM or other systems?+-
Yes, straight away through ready-made connectors for Salesforce, HubSpot, Zoho CRM, Microsoft Dynamics 365, Zendesk, Odoo, and Microsoft Teams, plus SSO through Microsoft Entra ID and Active Directory, and an open API for developers.
Is there a support team?+-
Yes — Thai specialists available 24 hours a day, every day, by phone, LINE OA, and email, with a guaranteed 99.9% SLA.
