New Features

Advanced CDR & Call Timeline

As one of the most anticipated features, Advanced CDR replaces legacy CDR with a single-call storage model and introduces a new CDR Details view, enabling admins to review every call performance more efficiently, identify issues faster, and fine-tune call strategies through more granular analysis, capabilities that are especially valuable in contact center scenarios where detailed call visibility matters most.

From Legacy CDR to Advanced CDR

Previously, with Legacy CDR, a single call was recorded as multiple fragmented records. With Advanced CDR, each complete call is stored as a single CDR, simplifying review and analysis. On top of this, new added CDR Details brings more granular insights into every call, including call recordings, traceable call timelines, call duration breakdowns and other call-related data. After upgrading, all new call records will be stored in the Advanced CDR format.

Key Enhancements in Advanced CDR

CDR Details: A new centralized table that brings together call recordings, timelines, call notes, and call duration insights. Admins can quickly search and filter CDR details by call type, participants, queues, ring strategies, and more ranges, greatly improving daily call review efficiency.
Call Recordings: Each call leg is recorded as an audio file, displayed as an interactive waveform that can be played, paused, or navigated by dragging. Admins can adjust playback speed and volume, download recordings, and jump directly to any part of a call for conversation review or call performacne analysis.
Call timeline: Tracks the full call interaction as a text-based journey, showing start/end points, routing paths, participants, notes, AI summaries and more interaction details, giving admins a complete view of each call for faster troubleshooting and analysis.
Time Breakdown: Provides a visual overview of call durations, including total call time, routing time, handling time, and other breakdowns, allowing admins to quickly understand call flow efficiency, identify delays or abnormalities, and make informed decisions for process optimization.
Call Note: Provides actionable insights for each call and can be edited directly within CDR Details, helping admins quickly capture key observations and make informed decisions.

CDR Management & Storage Improvements

Each complete call is stored as a single record to reduce database usage.
Supports automatic cleanup rules for long-term storage management.
CDR reports can be exported in CSV, XLS, PDF, or HTML formats for easy analysis and reporting.

PBX Dark Mode

The eye-friendly Dark Mode is now supported across all PBX clients, including the PBX Management Portal, Linkus Desktop/Web clients, the Linkus Chrome Extension, and embedded apps for Microsoft Teams and Dynamics 365 (Mobile clients already supported previously). It provides PBX users and admins with a brand-new, more comfortable experience.

Bypass Linkus SIP Blocking

Linkus Mobile Client leverages secure Tunnel technology to bypass SIP restriction issues, ensuring users stay reliably connected with stable, high-quality calls. By doing so, it effectively overcomes carrier-imposed limitations, including registration failures, unstable connections, and degraded call quality.

Additional Optimizations

File Remote Archiving Enhancements: Remote call recording archives now support both .wav and .mp3 formats, with configurable retention limits on third-party servers to improve storage flexibility and compliance control.
Expanded Virtual Fax Compatibility: Virtual Fax now adds support for the newly compatible IXICA platform, alongside existing providers such as Telnyx, IZT Cloud, and Pangea, allowing users to send and receive faxes directly through the PBX without a physical fax machine.
SMS Carrier Expansion: SMS integration carrier now supports Alhambra IT and Aspsms, alongside existing ITSPs such as General, Flowroute, Twilio, Telnyx, Bandwidth, SIPTRUNK and VOIP.MS.
Fanvil Auto-Provisioning Enhancement: All Fanvil phones now support phonebook provisioning via AutoP, simplifying bulk deployment and ensuring consistent contact synchronization.
Simplified DOD Switching via BLF: DOD switching and monitoring via BLF has been simplified. Users can now dial using Feature Code + DOD number or short code, removing the need to include the extension number and making daily operations faster and more intuitive.
