Improvements and Bug Fixes

Simultaneous Login on Multiple Devices (Multi-Client Login)

The Virtual-Call UC Client now supports simultaneous login on multiple devices. A single extension can remain logged in across different platforms at the same time—mobile app, desktop client, web client, and IP phone. The maximum number of concurrent logins per platform can be configured (Path: Extension and Trunk > Extension > User > Extension Information).

Additionally, super admins can now view and manage all logged-in UC Client devices of an extension—including remarks and remote logout (Path: Extension and Trunk > Extension > UC Clients > Currently Logged-in Devices).

Import Extension Data

Extension information can now be updated via file import (Path: Extension and Trunk > Extension > Import). If an extension number already exists in the system, its settings will be automatically updated with the data from the file.

AI Features—New Menu and Transcription Subscriptions

The built-in AI features (Text-to-Speech, Call Transcription, and Voicemail Transcription) have been moved from the previous Integrations menu to a new location: AI > AI Toolbox.

Additionally, add-on subscriptions for expanding the AI transcription quota are now available (Path: Plan > Add-on Subscription):

Contacts—Extended Contact Fields

The following new fields have been added for company contacts (Path: Contacts > Company Contacts):

• Organization
• Job Title
• Position
• Industry
• Supervisor

Speed Dial—New Remark Field

When adding a speed dial number, you can now fill in a remark field (Path: Call Features > Speed Dial). When calling the speed dial number, the remark is displayed alongside the phone number to facilitate identification.

Time Conditions—More Time Periods

The maximum number of custom business hours and time periods has been increased from 10 to 20. This affects the following features:

Event Notifications—New System Events

The following new event notifications have been added (Path: System > Event Notification > Event Type > System):

SIP Settings—Session Parameters

SDP session parameters can now be customized, including the session name and session originator, to meet specific carrier or device requirements (Path: PBX Settings > SIP Settings > Session > Session Parameter Configuration).

Microsoft Entra ID (Azure Active Directory) Integration

• The integration process has been simplified: setup can now be initiated directly from the PBX—only a Microsoft account login for permission consent is required. The PBX automatically creates the required application in Microsoft Entra ID without manual configuration.

  Note:
  Existing integrations using the previous method will continue to work without interruption.

• New configuration option User Avatar Synchronization: When enabled, user avatars are synced from Microsoft to the PBX extensions.

  

• Contact synchronization with Outlook has also been simplified—it now only requires configuration on the PBX, without additional permission setup in Microsoft.

Scheduled Reports

• New HTML file format for downloading scheduled reports.
• New Duration Format field to select the display format for all duration fields (seconds or HH:MM:SS).
• New Include Details option to choose whether call details should be included in the download.
• The delivery status of scheduled reports is now displayed in the log list.

Security

Overall system protection has been enhanced based on internal security reviews. Updating to this version is strongly recommended to ensure comprehensive protection against IP-based PBX threats and toll fraud.
