Yeastar P-Series Cloud Edition 84.24.0.122-beta1

New features

Message Flow Designer

Yeastar P-Series Cloud Edition provides the Message Flow Designer (MFD), allowing you to visually create and automate message workflows. With an intuitive drag & drop interface and fully configurable, pre-built components, you can effortlessly build messaging chatbots and auto-responders, significantly boosting team productivity and enhancing customer satisfaction.

For more information, see Message Flow Designer Overview.

In addition, the following related updates are introduced:

• Added Message Flow as a destination option for message channels, allowing inbound messages to be routed to a message flow.

  

• Added Message Flow and Third-Party Message Analytics Platform (Transmitted via API) as destination options for sessions in message campaigns, allowing you assign the session automatically created when sending a message to these destinations.

  

• Added support for role-based permission control for Message Flow Designer (Path: Extension and Trunk > Role > Automation Workflow > Message Flow Designer).

  

Yeastar for Teams Desktop Plugin

Yeastar P-Series Cloud Edition provides Yeastar for Teams Desktop Plugin dedicated for the integration with Microsoft Teams, which allows Teams users to make and receive calls without relying on Linkus Web Client, Linkus Desktop Client, or other SIP devices as CTI-controlled endpoints.

After installation, the plugin automatically connects to Microsoft Teams and runs in the background. When a call is received or initiated from Teams, the plugin is activated automatically to display the call interface, allowing users to handle the call without switching to another client or device.

For more information, see Yeastar for Teams Desktop Plugin Overview.

Improvements and bug fixes

Web Interface

Added support for the following web interface languages:

• Hrvatski jezik(Croatian)
• српски језик(Serbian)

System

Fixed the CPU overload issue: Excessively high CPU usage caused degraded PBX performance.

Extension

• Added support for adding and managing voicemail greetings, and assigning them to different presence statuses when bulk adding or editing extensions (Path: Extension and Trunk > Extension > Bulk Add/Edit > Voicemail > Voicemail Greeting).

  

  For more information, see Voicemail Greeting Overview.

• Added support for automatically sending SMS or WhatsApp messages to callers when calls to the extension are not answered and the trigger conditions are met (Path: Extension and Trunk > Extension > Features > Auto-Reply Message for Missed Calls).

  

  Note:

  • To use this feature, make sure that the PBX is integrated with an SMS channel or a WhatsApp channel, and the extension user has permission to create messaging sessions.

    For more information, see Set up an SMS Channel and Set up a WhatsApp Channel.

  • Extension users can also configure this feature on their Linkus Desktop or Web Client (Path: Preferences > Features > Auto-Reply Message for Missed Calls).

  For more information, see Configure Auto-Reply Message for Missed Calls.

• Added support for configuring outbound call recording prompt (Path: Extension and Trunk > Extension > Features > Prompt > Outbound Call Being Recorded Prompt).

  

  When an outbound call initiated from the extension is recorded, the system plays the configured prompt before recording starts to notify both parties that the call is being recorded.

• Fixed the function key issue: After applying a function key template to extensions in bulk, the existing function keys were not deleted, resulting in a mismatch with the template.

Trunk

Fixed the inbound call failure issue: Inbound calls through a trunk failed to connect, even though the trunk was shown as reachable in the web interface.

Contacts

Optimized the integration with Microsoft SQL: Added a Connection Encryption Mode configuration item (Path: Contacts > Company Contacts > Synchronize Contacts > Microsoft SQL), which allows you to specify the encryption mode for the connection between PBX and Microsoft SQL Server.

Auto Provisioning

• Removed the requirement to select at least one codec when adding or managing IP phones and custom templates.

• Fixed the authentication issue: Authentication failed during first-time auto provisioning when IP phones were added and assigned extensions in bulk.

• Fixed the Snom IP phone provisioning issue: When a Snom IP phone was already bound to a PBX, adding it to another PBX via RPS actually failed, but the RPS Request Success event was still triggered to indicate a success.

Inbound Route

Fixed the DID matching issue: After a time condition was enabled for an inbound route that routed calls to a call flow with DID number, the call flow number instead of the actual DID number was used for DID matching, causing calls to enter the wrong destination and be disconnected immediately.

Call Flow Designer

• Moved the feature entry from the first-level menu to the second-level menu. The new access path is Automation Workflow > Call Flow Designer.

  

• Added support for the following components:
  • Send SMS: This component allows you to send SMS messages to the original caller or a custom phone number.

    

  • Send WhatsApp Template Message: This component allows you to send WhatsApp messages to the original caller or a custom phone number.

    

  For more information, see Call Flow Components.

• Added support for modifying component names.

  

• Added support for displaying and copying the component ID, which serves as the unique identifier for the component.

  

• Optimized the experience in component and branch connection:
  • Dragging a component close to the end of another component or branch automatically connects them.

    

  • Multiple upstream components or branches can be connected to the same downstream component.

    

  • Business Hours, Menu, and Condition components can be added to branches other than ending branches.

    

• Fixed the DID issue: After a new DID number from a shared trunk was assigned to the PBX, all existing DID numbers from the shared trunk that were assigned to a call flow were cleared.

Voicemail

Added support for managing user-added voicemail greetings.

• (Extension Voicemail) Path: Extension and Trunk > Extension > Voicemail > Voicemail Greeting > Greeting Management > .

  

• (Group Voicemail) Path: Call Features > Voicemail > Group Voicemail > General > Group Voicemail Greeting > Greeting Management > .

  

Ring Group

• Fixed the simultaneous ringing issue: When simultaneous ringing on a mobile number was enabled for a ring group member extension, incoming calls to the ring group did not ring the mobile phone.

• Fixed the sequential ringing issue: When an incoming call to a sequential ringing group was not answered by the first member, the call was disconnected instead of continuing to ring the next member.

Queue

Added Auto-Reply Message for Missed Calls configuration item for queue in PBX web portal (Path: Call Features > Queue > Preferences) and API, allowing to automatically send SMS or WhatsApp messages when a missed queue call meets the predefined conditions.

Call Parking

Added the following timeout destination options for parked calls (Path: Call Features > Feature Code > Call Parking > Timeout Destination).

• Hang Up
• AI Receptionist
• IVR
• Call Flow
• Ring Group
• Queue
• Play Prompt and Exit

AI

• Added support for using the AI Receptionist's primary language to generate AI call summaries and AI insights.

• Fixed the AI voicemail transcription setup issue: Configuring AI voicemail transcription with Amazon service failed, with an error message indicating that the storage bucket already existed but was not owned by the account.

Messaging

• Added Country/Region configuration item dedicated for SMS and WhatsApp channels. The system automatically adds the specified country or region code to customer phone numbers that are not in E.164 format before sending messages.

  

• Added Send SMS and Send WhatsApp Template Message as keypress destination options for IVR and queue, allowing SMS or WhatsApp messages to be sent to the caller.

  

Email

Fixed the email issue: Notification emails were delivered, but no recipient was shown in the To field.

Voice Prompt

• Added support for creating and managing Music on Hold (MoH) playlists and MoH files from anywhere MoH is supported.
