Improvements and bug fixes

Call Flow Designer
  • Optimized the following call flow components:
    Component Description
    Call Control Component
    Prompt & UserInput Added a configuration item TTS Response Timeout under the Text to Speech prompt configuration.

    When enabled, the component provides two branches TTS Playback Success and TTS Response Timeout, allowing you to set distinct flow paths based on the TTS generation result (success or timeout).

    Menu & Dial by Number
    • Changed the branch name Invalid Input to No Match across these components.

    • Added a Matched branch for the Dial by Number component, which is directly connected to the Call End branch.
    Transfer
    • Added a transfer destination type IVR.

    • Added an option Dial Feature Code for the custom transfer destination. If enabled, you can set the feature code to be dialed in the Destination Number field.
      Note: Feature codes for in-call operations are NOT supported, such as Record (*1), Flip (*01), Transfer (*3, *03), and Park (*5, *05).
    Flow Component
    Condition Changed the branch name Invalid Input to No Match.
    Developer Component
    / The original Developer component on the left-side toolbox has been split into four standalone components, including Internal Data Ops, Email Sender, Database Access, and HTTP Request.
    Internal Data Ops This component provides Get and Set operations on the PBX's internal data supported by the original Developer component. In addition, the following changes are introduced:
    • Added the following Get operations:

    • Added an agent status Log in to Last Queues for the Set Agent Status component. If selected, the agents will be automatically logged in to all queues they were previously logged in to.

    • Added support for displaying the key configured items and content of the component in the workspace for easy identification.
    Email Sender
    • Added support for inserting variables in Subject and Content fields.

    • Added support for displaying the email subject in the workspace for easy identification.
    Database Access & HTTP Request
    • Added a configuration item Timeout Destination.

      When enabled, the component provides two branches Default Destination and Timeout Destination, allowing you to set distinct flow paths based on the execution result (success or timeout).

    • Added support for displaying the database server address (for Database Access component) or the request URI (for HTTP Request component) in the workspace for easy identification.
  • Optimized the End Key setting (Path: Call Flow Designer > Options > End Key), which allows you to set any numeric key (0-9) as the end key, or choose None to disable the end key feature.

  • Added the following variables and function for the call flow designer:
    Item Description
    Variable
    • Added a variable $GetExtensionStatus{index}.isUnavailable for the GetExtensionStatus component to indicate an extension's registration status.
    • Added the related variables for the GetSystemInfo, GetSystemCapacity, GetExtensionInfo, and GetCompanyContactInfo components.
    Function
    • Added a function GET_JSON_ARRAY_ITEM, which can be used to extract the object element at a specified index from a JSON array.

    For more information about the variables and functions, see Variables and Functions in Yeastar Expression.

Recording
  • Added support for setting up recording prompts for one-click recording (Path: Call Features > Recording > Recording Tones). If set, when authorized extension users start or stop call recording during a call, the system will play the corresponding prompt.

    For more information, see Set up Recording Prompt for One-click Recording.

SIP Settings
Added a configuration item Call Connection Assurance (Path: PBX Settings > SIP Settings > Advanced > Other Options) to ensure call connection stability for specified extensions.

This setting is designed to resolve the no-audio issue that could occur on the first Linkus call after a computer restarts in specific client environments (typically due to certain browser or OS limitations). When a specified extension logs in to the Linkus Desktop Client / Web Client, PBX will place a call to the client. The client will auto-answer and immediately hangs up, pre-establishing a stable connection path for all subsequent calls.
Note:
  • The entire process is invisible to the extension user.
  • The call does not consume call concurrency, and will not generate any call records.
Archive
Added the following configuration items for archive tasks (Path: System > Archive > Archive Task > Storage Configuration):

  • Storage Method: Choose how to store archived files based on task type (one-time or recurring), either in auto-created folders or directly under the selected storage path.
  • Organize Files by Date: Determine whether to automatically sort files into date-based subfolders (named in YYYYMMDD format ) within the storage path.
For more information, see Yeastar P-Series Software Edition Remote Archiving Overview.
Event Notification
Added a configuration item Capacity Alert Threshold for the Your AI Transcription Usage is Reaching the Capacity Limit event notification (Path: System > Event Notification > Event Type > Reminder > Your AI Transcription Usage is Reaching the Capacity Limit > Event Detail > Event Setting), which allows you to customize the capacity thresholds to receive alerts when the AI transcription usage reaches the thresholds.

Hot Standby
Optimized the Hot Standby feature: If the firmware version of the Primary Server and Secondary Server do not match, the hot standby status will show as Abnormal, and the system displays a firmware mismatch message prompting you to upgrade both servers to the same version, ensuring the Hot Standby feature functions properly.

Zendesk Integration
Updated the authentication mechanism of the Zendesk integration to comply with their updated authentication requirements.
Note: If your PBX has already been integrated with Zendesk, you can directly update the integration by simply clicking the Authorize button in the reminder prompt (Path: Integrations > Helpdesk) before the deadline, without the need to disconnect and re-configure the integration.

API
  • Optimized the API for the following features:
    Feature Description
    Web Server Added API interfaces for Web Server, which can implement the followings:
    • Query the current HTTPS certificate setting of the PBX web server.
    • Update the HTTPS certificate setting of the PBX web server.

    For more information, see Developer Guide - Web Server.
    Certificate Added API interfaces for Certificate, which can implement the followings:
    • Query certificate list
    • Query the information of one or multiple certificates
    • Upload and add a certificate
    • Edit or delete a certificate
    For more information, see Developer Guide - Certificate.
    Auto Recording Added parameters start_prompt and end_prompt for interfaces autorecord/get and autorecord/update, which can be used to query or set the prompt that will be played when authorized extension users start or stop recording during a call.
    Voicemail Added a parameter uid for interfaces vm/query, vm/get, vm/download, vm/update, and vm/delete, which can be used to query associated CDR ID, or to filter voicemails by CDR ID.
  • Added the following API events for the PBX system event notification.
    Event Description
    (30034) System Event Notification (Information) Indicate that an information-level PBX system event occurs.
    (30035) System Event Notification (Warning) Indicate that a warning-level PBX system event occurs.
    (30036) System Event Notification (Alert) Indicate that an alert-level PBX system event occurs.

Trunk
Fixed the SIP trunk issue: Calls made over a SIP register trunk (remotely registered using a public IP) were connected successfully but had no audio.
CDR
Fixed the CDR issue: When an agent answered an inbound queue call but the caller hung up during the agent ID announcement, the system did not generate the corresponding CDR for the agent extension.
