Improvements and bug fixes

My Subscription
Added support for displaying AI monthly quota packs separately by minute specifications. For each specification, the used, available, and total minutes are displayed (Path: My Subscription > AI Transcription (Monthly Quota Pack) / AI Receptionist (Monthly Quota Pack) > Type).

Cloud PBX

Fixed the OEM ID issue: The OEM ID displayed for some Cloud PBX instances in Yeastar Central Management did not match the corresponding OEM ID recorded in Yeastar Partner Portal and the PBXs.

Repository

Added support for restoring backup files across P-Series Appliance Edition, P-Series Software Edition, and P-Series Cloud Edition.

Note: When restoring a backup file to a PBX running a different product edition, the network configuration is not restored.

Feature Description

Optimized Optimized the following API interfaces for Cloud PBX:
  • Added the request parameter subordinateUserId to the /dm/open_api/v1/cloud_pbx/instances interface, allowing to create a Cloud PBX instance for a subordinate user.
  • Added the response parameter ownerUserId to the /dm/open_api/v1/cloud_pbx/instances/{cloudPbxId} and /dm/open_api/v1/cloud_pbx/instances/get interfaces to return the unique ID of the PBX owner.

For more information, see Developer Guide - Cloud PBX.
Domain Optimized Optimized the Domain API:
Firmware Optimized Optimized the Firmware API:
  • Added the request parameter subordinateUserId to the /dm/open_api/v1/firmware interface to query the firmware versions available to a subordinate user.

    For more information, see Developer Guide - Query Available Firmware.
Backup Files Optimized Optimized the Backup File APIs:
  • Added the values hardware_pbx and software_pbx to the response parameter backupFileType for the /dm/open_api/v1/backup_file interface to indicate the product edition of the PBX from which a backup file was generated.

    For more information, see Developer Guide - Query all the Backup Files.

  • Added the request parameters backupFileType and restoreNetwork for the /dm/open_api/v1/backup_file/restore interface to support restoring a backup file to a PBX running a different product edition.

    For more information, see Developer Guide - Restore a Backup.
Domains
  • Fixed the following certificate issues:
    • When the SBC and SBC Proxy certificates were configured for domains within the same DNS zone managed by cPanel, the SBC certificate renewal succeeded, but the Proxy certificate renewal failed.

    • Saving a certificate for a domain hosted on Hetzner failed, because the system used the deprecated Legacy DNS Console API, resulting in a DNS provider authentication error.

    • Automatically applying a certificate for a domain hosted on ClouDNS failed, because the domain's name servers had not finished synchronizing.

  • Fixed the client IP spoofing issue: A forged X-Forwarded-For header could cause the system to identify a spoofed IP address as the actual client IP, potentially allowing IP-based access controls to be bypassed.

Security
  • Fixed the security issue related to CVE-2026-98432: TCP connection requests containing IPv4 options could trigger a use-after-free vulnerability, potentially causing the YCM server to crash.
