Improvements and bug fixes

Web Interface
Added support for the web interface language Türkmenistan (Turkmen).
Extension
  • Added a configuration item Notification Email Language, which allows for customizing the language of email notifications for an extension individually (Path: Extension and Trunk > Extension > User > Language).
    Note: This setting only applies to the system's default email templates, and is ignored for custom templates.

  • Optimized the voicemail language settings of extensions: The entry of the feature settings has been moved from Extension and Trunk > Extension > Voicemail to Extension and Trunk > Extension > User > Language, allowing for customizing the prompt language that callers will hear when accessing the extension's voicemail.
Linkus Server
Added support for configuring the valid period (in days) of the login credentials sent in the Linkus Welcome Email (Path: Extension and Trunk > Extension > Linkus Server > Email Template > Login Credentials Validity Period (Days)).
Trunk
  • Added a configuration item Generate Linked Hostname, which allows you to decide whether to use FQDN or NAT domain name as the hostname for generating the WebRTC Inbound Call Link and Default Call Template Embed Link.

  • Fixed the trunk issue: After recovering from an unexpected network disconnection, outbound calls through SIP register trunks failed.
Auto Provisioning
  • Added support for auto provisioning the following Yealink phones:
    • T85W, T87W, T88W, T88V
    • T73W, T73U, T74W, T74U, T77U
  • Added support for auto provisioning the following Gigaset phones via RPS method:
    • P820 IP PRO
    • P850W IP PRO
    • P710 IP PRO
  • Added support for downloading and uploading auto provisioning custom templates (Path: Auto Provisioning > Resource Repository > Custom Templates), which allows template reuse across multiple PBXs without the need to recreate templates manually.
    Note: The downloaded template files are encrypted and cannot be opened directly; they can only be uploaded and parsed by the PBX.

Hot Desking
Added support for retaining phone configurations when extension users log out of a Hot Desking phone.
Note: To achieve this, you need to enable the option Retain phone configuration when Hot Desking guests log out (Path: Auto Provisioning > Phones > Options).

For more information, see Retain Configurations for Hot Desking Phones.

Paging/Intercom
  • Added a configuration item Prompt Playback Times, which allows you to specify how many times the prompt will be played and repeated (Path: Call Features > Paging/Intercom).

  • Added a configuration item Dial # to Stop Playing Prompt, which allows you to specify whether broadcaster(s) can dial # to stop playing the prompt during playback when a specific prompt is configured for a paging group (Path: Call Features > Paging/Intercom).

System Preference
Added support for customizing presence statuses and corresponding icons, providing greater flexibility in indicating extension users' availability (Path: PBX Settings > Preferences > Presence).
Note: The custom presence setting will be synchronized across Linkus UC Clients with the following versions:
  • Linkus iOS Client: Version 5.15.8 or later
  • Linkus Android Client: Version 5.15.4 or later
  • Linkus Windows Desktop: Version 1.13.3 or later
  • Links Mac Desktop: Version 1.13.3 or later

For more information, see System Preferences.
Public IP and Ports
Added a configuration item Prioritize NAT over FQDN, which allows you to define the priority of NAT and FQDN when both are enabled (Path: System > Network > Public IP and Ports > Public IP (NAT)).
If this option is enabled, the system will use the NAT address instead of the FQDN when generating remote access URLs, such as Linkus login link, Live Chat embed code, etc.
Hot Standby
Added Maintenance Mode for Secondary Server. When Primary Server is under maintenance (e.g. firmware upgrade or system reboot), it may fail to respond to heartbeat packets from Secondary Server. In this case, you can enable and schedule Maintenance Mode on the Secondary Server to temporarily suspend health monitoring, so as to prevent takeover during the maintenance window.

For more information, see Enable and Schedule Maintenance Mode on Secondary Server.

Active Directory Integration
