Previous Release - VSF-Display Series 9.3 Release Notes

This document provides the release notes for VSFF8MP 9.4 with incremental bug fix releases. The release notes describe new features, improvements and issues fixed after vsff8mp-9.3.3.1.

Release info

Name: VSF-Fortitude8
Description: vsff8mp is a firmware for devices in the Zenitel Display Series.

The firmware is delivered in two different files:

Version: 9.4.3.0
Date: 30.01.2026
Status: General Availability

VSFF8MP 9.4.3.0

Improvements

DS-1638 The default Acoustic Echo Cancellation (AEC) profile is tuned for better double-talk and voice quality.

The default AEC filter configuration is set to do less processing of the audio signal for best voice switching, double-talk and voice quality. When installed in challenging environments using high volume settings, the AEC level might have to be set to Moderate or High to remove echo return.

DS-1613 ZDD now has search option for address book

User can enable search option over web. Keyboard will appear to search contacts.

DS-1585 Far-End Signal Squelch configuration changes needed reboot to apply

Now Squelch parameters are applied on the-fly when saving changes.

DS-1557 New option to hide the on screen clock

A new setting is now available on the device web interface that allows to hide the on screen clock.

DS-1553 Reduced audible hiss from ZMK-1/RDP speaker when idle or at low audio levels

The ZMK-1/RDP now disables the speaker amplifier when there is no active audio. If Far-End Signal Squelch (FESS) is enabled, active squelch will also disable the amplifier, reducing audible hiss when the line is idle or audio levels are low.

DS-1516 Relays/outputs can now be triggered by multicast paging streams

The activation is following the audio stream priorities in the multicast paging.

DS-1259 In the Hostname field the maximum number of characters is increased to 64

Fixed Issues

MTN-4820 The Volume settings in the web interface accepted input values outside the defined maximum/minimum range.

Volume settings now only accepts input values within the defined maximum/minimum range.

MTN-4709 Fixed an issue where logo upload failed for filenames over 50 characters

Previously, uploading a logo file with a filename longer than 50 characters would fail silently, resulting in a broken image link in the browser. Deleting the missing logo could cause the device to reboot. This issue has been resolved: uploads with filenames exceeding 50 characters are now blocked with an error message, preventing broken images and device crashes.

Security Updates

MTN-4795 Fixed multiple vulnerabilities

Fixed multiple vulnerabilities registered under CVE-2025-64126, CVE-2025-64127, CVE-2025-64128, CVE-2025-64129, and CVE-2025-64130. These vulnerabilities were associated with legacy web interface components. The affected functionality has been removed or redesigned to prevent misuse.

Action: Upgrade to version 9.3.3.0 (8.2.3.4 for TCIV legacy hardware) or later to ensure the latest security enhancements are applied.

DS-1555 Security Update

Resolved vulnerabilities related to:

CVE-2025-59817 Authenticated Remote Code Execution “zForm_auto_config”
CVE-2025-59818 Authenticated Remote Code Execution “zForm_upload_scripts”.

Action: Upgrade to 9.3.3.0 or later (8.2.3.4 for legacy TCIV)

 ==Fixed Issues==
-=== MTN-4796 ONVIF Subscribe Enhancements===
+=== MTN-4820 The Volume settings in the web interface accepted input values outside the defined maximum/minimum range.===
-Subscription requests now accept any namespace in the Address field.
+Volume settings now only accepts input values within the defined maximum/minimum range.
-The “wsnt:Filter” element is now optional. If omitted, the subscription will include all topics by default.
+=== MTN-4709 Fixed an issue where logo upload failed for filenames over 50 characters===

This issue has been resolved: uploads with filenames exceeding 50 characters are now blocked with an error message, preventing broken images and device crashes.
-=== MTN-4742 ONVIF Improvement: Default Video Source Configuration===
-GetVideoSourceConfigurationOptions now returns a default video source configuration even when no configuration is specified.
-=== MTN-4688 Fixed issues with ONVIF backchannel RTSP failures on missing media===
-Now always creating full media pipeline for backchannel to ensure better compatibility.
-=== MTN-4681 Ringing tone in ICX/AlphaCom now depends on setting in AlphaPro===
-Ringing tone level in ICX/Alphacom mode was low and did not respond to the Ringing Volume setting configured in AlphaPro. This is now fixed, ringing tone level is higher and dependent on value set in AlphaPro.
-=== MTN-4566 Removed Partial Reboot Option===
-The Partial Reboot option has been removed from the device web recovery page.
-=== MTN-4474 Multicast paging no longer gets interrupted or stopped on unrelated config changes===
-Audio will no longer be interrupted or stopped when unrelated configuration change, such as adjusting the volume, are made.
-=== DS-1572 Audio Setup Real-Time challenges===
-Observed on Connect case call to queue four duplicated SDP in short time interval causing up two 4 start and stop on one setup. This optimization deprecates memory intensive AEC context save and restore by keeping state in code-object between calls. Also added state handling on new Audio Session separating network audio and audio engine initialize in different steps.
-=== DS-1571 Duplicated SDPs from SIP-Invite/Re-Invite causes multiple audio start/stop with possible side effects===
-Observed on Connect case call to queue four duplicated SDP in short time interval causing up two 4 start and stop on one setup. This optimization check for duplicated SDPs in Re-Invites and do nothing if repeated with same parameters.
-===DS-1527 Zenitel Connect – Increased Virtual DAK Entry Limit ===
-Fixed an issue where Virtual DAKs were limited to a maximum of 9 entries. Attempting to configure more than 9 entries caused configuration scrambling and an effective cap at 10 entries. The limit has now been lifted to support a larger number of entries reliably.
-=== DS-1502 Multicast paging could stop working under some rare conditions===
-Multicast paging would stop working under some rare conditions, this is now fixed.
