Improvements and bug fixes

Web Interface
Added support for the following web interface languages:
  • Catalan
  • Hungarian
Extension Group
Fixed the member list display issue: When an extension's first name or last name was set to null via API, the member list of the extension group to which it belongs appeared empty, and querying the extension group via API returned no response data.
Auto Provisioning

  • Added support for retrieving configuration files via HTTP to auto provision Cisco SPA-series IP phones.

  • Fixed the random phone password generation issue: After bulk adding Yealink IP phones with the Generate a random phone password option enabled, the system failed to generate the Var Phone Password and User Phone Password for the first phone.
Inbound Route
Fixed display issue of inbound route list: When creating an inbound route, if a default destination was set and Time Condition routing was subsequently configured before saving, the route was not displayed in the list but remained functional.
Call Flow Designer
Fixed the DID number issue: If a DID number of a trunk was assigned to a call flow, when modifying the trunk settings (other than DID number), the DID number no longer displayed in the call flow list, and calls to the DID number were not routed to the call flow.
Voicemail
  • Added an Encrypted Voicemail Storage setting (Path: Call Features > Voicemail > Voicemail Settings > Encrypted Voicemail Storage). When enabled, voicemail messages are encrypted when stored to prevent unauthorized access to the message content.

    For more information. see Encrypted Voicemail Storage.

  • Added a No Greeting option for the voicemail greetings. When selected, the system will not play a greeting before callers leave voicemail messages.

    The option is available in the following settings:

    Setting Illustration
    Extension voicemail greeting (Path: Extension and Trunk > Extension > > Voicemail > Voicemail Greeting)
    Group voicemail greeting (Path: Call Features > Voicemail > Group Voicemail > > Group Voicemail Greeting)
    Global voicemail greeting (Path: Call Features > Voicemail > Voicemail Settings > Greeting Options > Global Voicemail Greeting)
AI Transcription
Fixed the AI transcription usage display issue: The usage was counted in seconds but incorrectly displayed as minutes, causing the displayed usage to be significantly higher than the actual usage.
Message Channel
Optimized the authentication mechanism of the Bandwidth SMS channel integration to comply with their updated authentication requirements. The integration uses Client ID and Client Secret for authentication instead of Username and Password.

Note: If you have an existing integration, to avoid service interruption, you need to update it before December 2, 2026.

Directly click the Update Authentication button on the channel's authentication configuration page (Path: Massaging > Massage Channel > > Authentication), and fill in the new OAuth 2.0 credentials generated from your Bandwidth account, without the need to disconnect and re-configure the integration.

For more information, see Set up an SMS Channel for Bandwidth.

Hot Desking
Fixed the hot desking login issue: After bulk updating voicemail access PIN for extensions, the extension users were unable to log into hot desking phones using the updated PINs.
Storage
Fixed network drive detection issue: A network drive had been successfully mounted to the PBX via Samba 3.0 protocol, but the PBX incorrectly displayed the status of the network drive as unmounted and failed to retrieve its disk capacity information.
Microsoft Entra ID (Azure Active Directory) Integration
Fixed the following user synchronization issues:
  • When the User Range for Extension Auto Creation was set to Users in Specific Group, newly added users in specified Microsoft Entra ID group(s) were successfully synced to PBX extension list but were not added to the corresponding extension group(s) that were synced from Microsoft Entra ID.

  • Syncing users with blank email addresses from Microsoft Entra ID to the PBX cleared the email fields of the corresponding PBX extensions, resulting in the relevant users being unexpectedly logged out of their Linkus UC Clients.

  • After enabling the Microsoft Teams User Presence Synchronization feature for more than 200 extensions in bulk, the CPU load reached 100%.
CRM/Helpdesk Integration Template
  • Added support for saving a default template as a custom template.

  • Added support for editing XML content of a custom template directly in the view window.

    For more information, see Edit a Custom CRM Template and Edit a Custom Helpdesk Template.

When enabled, the system will send keep-alive requests to the CRM/Helpdesk at the specified interval to monitor connection status and authentication validity, so as to prevent the connection from being closed due to network timeout or inactivity.

    • Optimized Authentication Method configuration: When configure OAuth2 authentication on the template configuration page, you can add up to 10 custom fields , and specifying whether each field is mandatory using the Required field.

    • Optimized the Call Journal configuration: Added the configuration items Create Call Log Request Method and Update Call Log Request Method, which can be used to specify the request method as POST or PUT.

  • Optimized the filters in CDR list.

    • Added column header filters Source Trunk, Destination Trunk, and DID/DDI.
    • Moved the Outbound Caller ID and PIN Code filters from top filters to column header filters.

Recording File
Fixed the recording playback and download issue: Archived recording files of inbound calls to queues or ring groups could not be played or downloaded.

Optimized the Extension Call Statistics report: For a monitored call, the report separately displays two entries containing call metrics for the monitored party and the monitoring party.

API
  • Added API interfaces for CDR in openapi/v2.0, which can be used to query CDRs and set CDR options.
    Note: The query interfaces in openapi/v2.0 can only used to retrieve CDRs generated on version 37.21.0.117 or later.

  • Optimized the API event 30013 (Call Transfer Report): When a blind transfer occurs, the destination extension number is also included in the report.
