P-Series PBX V24.3 BETA Updates

AI Receptionist: Plug Into Your Existing Stack

Beyond 24/7 automated greetings and smart routing, modern businesses require virtual assistants that transform conversations into immediate business actions. The P-Series PBX V24.3 BETA introduces Custom Tool Integration for AI Receptionist, enabling the AI to trigger live workflows and execute database tasks mid-call without human intervention.

Operating over secure HTTP, the AI Receptionist seamlessly interacts with your essential business applications, such as CRMs, scheduling platforms, order management systems, and inventory databases, to automate tasks like booking appointments or retrieving order updates.

Key Capabilities:

  • Flexible Low-Code Setup: Easily configure custom tool connections using intuitive Form-based or JSON-based editors to match your exact business logic.
  • Granular Virtual-agent Assignment: Assign specific configured tools to individual virtual agents, driving purpose-built automation for diverse business scenarios.
  • Full CDR Tracking: Track the entire tool invocation process and execution results directly within the CDR for effortless auditing and rapid troubleshooting.

*To configure custom tools for your AI Receptionist, please follow our detailed Configuration Guide.

Call Quality Monitoring

To maintain call stability and accelerate network troubleshooting, the P-Series PBX introduces end-to-end QoS (Quality of Service) Monitoring. Delivering comprehensive visibility across all audio calls, video sessions, and conference rooms, this feature empowers both users and PBX admins to effortlessly track RTP stream health and diagnose connection issues.

Call-Quality-Monitoring

Key Capabilities:

  • User-Level Quality Tracking (Real-Time & Post-Call): Extension users can monitor live QoS metrics during the call or check post-call performance reports in their call logs via Linkus Desktop/Web/Mobile Client. By tracking metrics like latency, transmit (TX), and receive (RX) data (such as packet loss and jitter), users can easily identify local network drops and report call-quality issues accurately to admins.
  • Granular Admin Diagnostics via CDR: Admins can drill down into any specific call within the CDR to review historical network metrics, allowing them to instantly isolate whether a voice glitch was caused by local network congestion or a remote ISP.
  • Multi-Dimensional QoS Analytics: Through the Call Report dashboard, admins can generate aggregated quality statistics filtered by extension, time range, or client type to systematically optimize system performance.

*To configure QoS monitoring permissions and access for extensions and admins, please follow our detailed Configuration Guide.

Refined Linkus Mobile UX

We’ve refined the Linkus Mobile Client to deliver a smoother, more efficient calling experience for PBX remote and mobile users. This main update focuses on interface clarity and navigation convenience:

  • The dialpad is now a primary, standalone tab, giving you instant, one-tap access to make direct calls without navigating through extra menus.
  • Mobile users can now choose between two brand-new call panel layouts to match their personal viewing preferences and workflow habits.
  • A new, distinct recording icon appears dynamically on the calling panel when a call is being recorded.
  • Status icons in the upper-right corner of the calling interface have been redesigned to help users intuitively and instantly identify their current call status.

P-Series Additional Optimizations

  • Expanded TAPI Scalability: The TAPI integration now supports simultaneous login for up to 50+ concurrent users, significantly boosting performance for high-density workplace scenarios.
  • Enhanced Cisco AutoP Flexibility: The Cisco SPA series IP phones now support AutoP via HTTP protocol.
  • Bandwidth SMS Authentication Update: Bandwidth has officially updated its authentication requirements. To ensure uninterrupted service, please update your authentication configuration in the PBX by December 2, 2026. All other functionalities remain unaffected.

YCM Updates (For distributors & resellers)

Yeastar Central Management (YCM) is a remote management platform for Yeastar PBX systems and gateways. This update is already available for hosted users and will be released on July 3 for BYOI deployments. Read on to explore the latest updates.

Bulk Phone Firmware Upgrade

Manually upgrading IP phone firmware or constantly logging into individual PBX interfaces is highly tedious and time-consuming for partners managing large-scale or multi-model phone deployments. To eliminate this operational bottleneck, the latest YCM platform allows users to configure automated tasks and push bulk phone firmware updates across multiple PBXs directly from a single dashboard.

Bulk-Phone-Firmware-Upgrade

How It Works & Capabilities:

  • Centralized Firmware Repository: A new Firmware > Phone Management menu has been introduced, enabling users to upload and centrally manage phone firmware versions before deployment.
  • Upgrade Task Configuration: Users can schedule or initiate updates by selecting the target PBX type, phone firmware version, task type, and specific phones (individually or in bulk) to deploy the firmware without any manual phone-side configuration.
  • Complete Execution Logs: Once the deployment finishes, the system automatically displays the precise upgrade results and success status directly within the YCM Extension Log, providing immediate visibility for verification and troubleshooting.

*To configure phone firmware upgrade tasks, please follow our detailed Configuration Guide.

Shared Trunk Channel Quota Management

Managing shared trunks across multiple downstream tenants or PCE instances often risks channel exhaustion and chaotic resource allocation. To ensure stable operations, YCM now provides comprehensive Shared Trunk Channel Quota Management, enabling upstream partners to easily allocate concurrent call (CC) resources, enforce access control, and monitor shared trunk usage from a single dashboard.

Key Capabilities:

  • Granular CC Allocation: Super Admins, Hosting Users, and Resellers can define a Maximum Concurrent Calls (CC) quota when creating or editing a PCE instance with shared trunk aasignment, preventing over-utilization and ensuring sufficient channel resources for all downstream users.
  • Hierarchical Access Control: Upstream partners can assign specific Shared Trunk Access Control permissions to downstream users, ensuring clear consumption boundaries across the entire distribution tier.
  • Trunk Resource Usage Monitoring: YCM dynamically tracks and visualizes CC usage and trunk utilization data, providing users with the clear visibility needed for efficient capacity planning.
  • Proactive Threshold Alerts: To prevent unexpected call drops, the system automatically triggers warning notifications when consumption hits set thresholds, alerting individual downstream users when their assigned limits are reached, and notifying Super Admins immediately if the overall shared trunk capacity faces depletion.

*To configure shared trunk quotas and threshold alert settings, please follow our detailed Configuration Guide.

Microsoft SSO Sign-in

YCM now supports Single Sign-On (SSO) via Microsoft, providing users with a more secure and convenient login experience.

  • Complete Microsoft Integration: Connect YCM with Microsoft under the Collaboration menu. To enable Microsoft SSO, BYOI users should complete the corresponding configuration on the Microsoft portal first.
  • Configure Login Methods: Set the preferred authentication policy by enabling Account password login, SSO sign-in, or allowing both options simultaneously.
  • Enforced Login Access: Users must log in strictly using the allowed methods configured in the policy.
