In brief: Yeastar released P-Series V23.1 as a GA build on 2 March 2026, adding messaging, call management, and API improvements. SA resellers on P-Series should schedule customer updates.
Yeastar released P-Series Software Edition 83.22.0.17 (V23.1) as a General Availability (GA) build on 2 March 2026, clearing Alpha and Beta cycles and making it ready for production deployment. The update is available to all P-Series Software Edition customers from the system’s built-in update manager.
If you’re a Yeastar reseller, this article is written for you — not for system administrators. The question that matters for your role isn’t “what changed technically” but “what should I be telling my customers, and is there anything in here that could cause problems or create a sales opportunity?”
The headline improvement: Call Flow Designer
V23.1 delivers more than ten improvements to the Call Flow Designer — and this is worth paying attention to if you haven’t been using it as a selling point.
Call Flow Designer is one of the features that separates Yeastar from simpler hosted PBX solutions like basic switchboard products. It gives non-technical administrators a visual, drag-and-drop interface for building sophisticated call routing logic — time-based routing, IVR menus, queue management, conditional forwarding, and more — without custom scripting or PBX expertise.
In the South African market, the most direct competitive comparison is with 3CX’s Call Flow Designer (which many former 3CX resellers already know), and with Euphoria Telecom’s routing tools. Yeastar’s implementation has been catching up and, in many configuration scenarios, now exceeds 3CX’s equivalent. Each update cycle closes the gap further.
For resellers proposing Yeastar to multi-site businesses, call centres, or customers with complex routing requirements — the Call Flow Designer improvements are a genuine conversation point. The V23.1 enhancements specifically focus on building more complete call flows and giving administrators greater control over routing logic. Full technical details are in the official release notes.
Fax-over-IP: BlueFax integration
P-Series systems can now integrate with BlueFax for internet-based fax, allowing businesses to send and receive faxes via the Linkus Desktop or Web Client without fax hardware.
It’s worth noting: BlueFax is an international provider and may not be the most cost-effective or locally-supported option for South African businesses. Local alternatives for fax-over-IP in South Africa include FaxFX (a widely used local provider) and services offered through some SIP trunk providers. If your customers need fax-over-IP, verify whether their existing SIP trunk provider supports T.38 fax before recommending a third-party fax service — that’s often the simpler and cheaper route.
The broader point is that fax capability in a hosted PBX remains relevant for certain sectors — healthcare, legal, government — where fax is still required for compliance or contractual reasons. V23.1 expands the options for how Yeastar customers can address that requirement.
AI Transcription usage controls
Administrators can now set threshold-based alerts for AI Transcription usage, giving better visibility and control over transcription spend. This is relevant for customers who have enabled AI call transcription at scale — particularly if they’re on a consumption-based transcription licence. The improvement prevents unexpected overage costs by alerting admins before thresholds are breached.
For resellers managing Yeastar Cloud PBX deployments, this is a useful operational improvement that reduces the chance of a customer receiving a surprise bill.
SMS provider expansion
V23.1 adds support for two additional SMS providers — VoIP.ms and NETPLANET. Neither is a primary South African provider (VoIP.ms is North American; NETPLANET’s SA presence is limited), so this addition has minimal direct impact on local deployments.
For SA-based SMS integrations, the more relevant question for your customers is whether their preferred local SMS provider — such as Clickatell, BulkSMS, or providers within Yeastar’s existing supported list — is already supported. Check the Yeastar documentation or contact Even Flow or Pinnacle ICT for current SA-compatible SMS provider status.
Should you upgrade now?
For most P-Series Software Edition deployments, yes — V23.1 is a GA (General Availability) release, meaning it’s been through full testing cycles and is recommended for production. However:
- If your customer has heavily customised Call Flow Designer configurations, review the release notes for that section specifically before upgrading, as some logic may behave differently.
- As with any production system upgrade, schedule it during a low-traffic period and ensure a backup exists before proceeding.
- Yeastar Cloud PBX (fully managed) customers will receive the update on Yeastar’s schedule and don’t need to take manual action.
About Yeastar P-Series
The Yeastar P-Series is available in three editions: Software Edition (self-hosted, on any server or cloud VM), Appliance Edition (dedicated hardware), and Cloud Edition (fully managed by Yeastar). In South Africa, it’s distributed through Even Flow and Pinnacle ICT (as of February 2026). See the Yeastar vendor profile on Telecoms Channel for partner resources.
Frequently asked questions
How do I upgrade a Yeastar P-Series Software Edition system to V23.1?
Updates are available from within the system’s admin interface under Maintenance > Upgrade. Yeastar recommends backing up your system configuration before upgrading. Review the V23.1 release notes for any configuration changes that may affect your setup.
Does V23.1 affect Yeastar P-Series Appliance or Cloud Edition customers?
The V23.1 version number applies to the Software Edition release cycle. Appliance Edition customers receive firmware updates on a separate schedule. Cloud Edition customers are updated by Yeastar automatically — no action required.
What is the Yeastar Call Flow Designer and how does it compare to 3CX?
Yeastar’s Call Flow Designer is a visual, no-code interface for building call routing logic — IVR menus, time-based routing, queues, conditional forwarding, and more. It’s broadly comparable to 3CX’s Call Flow Designer, which many SA resellers are already familiar with. Yeastar’s implementation has been improving significantly through 2025 and 2026, and for most SME and mid-market routing scenarios, it now offers comparable or better flexibility.
Can Yeastar P-Series send and receive faxes in South Africa?
Yes, via fax-over-IP. Options include BlueFax (newly supported in V23.1), and T.38 fax via compatible SIP trunks. For South African deployments, check with your SIP trunk provider (including local options like FaxFX) for the most cost-effective local solution before implementing a third-party fax service.
Which South African SMS providers are supported by Yeastar P-Series?
Yeastar P-Series supports multiple SMS providers through its SMS integration module. For South African providers specifically (such as Clickatell or BulkSMS), check the current supported provider list in the Yeastar documentation or contact Even Flow or Pinnacle ICT for confirmation. The V23.1 additions (VoIP.ms and NETPLANET) are not primarily SA-focused providers.
