Yeastar P-Series PBX in South Africa: supplied, installed and supported

Updated for October 2026

Hosted Yeastar P-Series Cloud PBX, Enterprise plan, set up and supported by Outsource Digital.

There is nothing to install or maintain at your office, and it works from any office, from home or on a cellphone. The Yeastar P-Series is a business phone system built for companies that have outgrown an old PABX. It puts your switchboard, call centre and team chat in one system, and lets your staff answer the office number on a desk phone, a computer or a cellphone.

Outsource Digital is a Yeastar Certified Partner. We set up and support the P-Series Cloud PBX for companies throughout South Africa and into Namibia and Eswatini, with offices in Midrand and Nelspruit and service partners in all the major cities.

What is the Yeastar P-Series?

It is a PBX: the system that runs your office phone calls. It answers incoming calls, sends them to the right person or team, connects your desk phones and apps, and records what happened.

Yeastar makes the P-Series as a box for your office, as software for your own server, and as a hosted cloud system. Outsource Digital supplies the hosted Cloud Edition on the Enterprise plan:

  • Nothing on site: no box to install or maintain at your office.
  • Works anywhere: from any office, from home or on a cellphone.
  • One system for every size: from small businesses to enterprise customers, including multi-branch enterprises, on one system.

A few features are available on request or as an add-on. We mark those below.

Replacing an old PABX? We upgrade you to Yeastar P-Series

If your office still runs an old Panasonic, Samsung or other PABX, we don't patch it. We replace it and move you onto the hosted Yeastar P-Series Cloud PBX, and your staff get a modern system with apps, call centre tools and integrations an old PABX can't offer.

Your numbers move with you: we port your landline numbers to the new system, and the old lines stay on until the move is confirmed.

What can the Yeastar P-Series do?

Everything below is included in our Enterprise plan unless it says otherwise.

Everyday calling

  • Auto attendant (IVR): "Press 1 for sales, 2 for accounts", with different menus for office hours, after hours and public holidays.

  • Transfer, park and pick up calls.
  • Conference rooms.
  • Voicemail, and voicemail to email.
  • Music on hold.
  • Call recording.

Apps for every device

  • The Linkus app for iPhone, Android, Windows, Mac and web browser, plus a Google Chrome extension.
  • Your office number rings on the app wherever you are, and customers see the office number when you call them.
  • Team chat between staff.
  • Operator panel for reception: see who is busy, drag calls to a colleague.

Call centre

  • Skill-based routing: calls go to the agent best suited to them.
  • Queue callback: callers can hang up and get called back instead of waiting.

  • Automatic blocking of hacking attempts, plus a global blocklist of known bad addresses.
  • Two-factor sign-in.
  • Limits on which countries can be called, and how often, to stop toll fraud.
  • Yeastar holds ISO 27001 and ISO 9001 certification and follows GDPR.
  • Yeastar states 99.99% reliability for its cloud, with 24/7 monitoring. This is Yeastar's figure, not an Outsource Digital guarantee.

What does a Yeastar PBX cost in South Africa?

We do not publish prices. It depends on:

  • How many users you need.
  • Whether you want any of the features available on request.
  • How many desk phones you want, if any.

Questions about Yeastar P-Series PBX

Is your Yeastar P-Series a cloud PBX or an on-site PABX?

Ours is a cloud PBX. We supply the hosted Yeastar P-Series Cloud Edition on the Enterprise plan, so there is nothing to install or maintain at your office.

Can I keep my business number?

Yes. We port all your landline numbers to the P-Series, so callers keep dialling the numbers they know. A new customer starts on a VoIP number and can port the existing landline across, with the old lines kept on until the move is confirmed.

Can staff answer the office number on their cellphones?

Yes. The phone app rings on Android and iPhone, and shows your office number when staff call out.

Does it work with Microsoft Teams?

Yes. Microsoft Teams, Outlook and Entra ID are included on the Enterprise plan we supply, and Yeastar's October 2026 update adds a Teams plugin so staff can make and take office calls inside Teams.

Can you replace my old Panasonic or Samsung PABX?

Yes. We replace it and move you onto the hosted Yeastar P-Series Cloud PBX.

Do you sell and support Yeastar outside Gauteng?

Yes. We support companies throughout South Africa and into Namibia and Eswatini, with service partners in all the major cities and offices in Midrand and Nelspruit.
