Previous Release - VSF-Fortitude8 9.3 Release Notes

This document provides the release notes for VSF-Fortitude8 9.3 with incremental bug fix releases. The release notes for VSF-Fortitude8 9.4 describe new features, improvements and issues fixed after VSF-Fortitude8 9.3.3.1.

Release info

Name: VSF-Fortitude8
Description: VSF-Fortitude8 is a firmware for Zenitel devices based on the IMX8 processor.

The firmware is delivered in two different files:

vsff8-9.4.3.x - Used for standard in-field upgrades
vsff8-prod-9.4.3.x - Used in production- and recovery upgrades.

Version: 9.4.3.1
Date: 30.01.2026
Status: General Availability

VSF-FORTITUDE8 9.4.3.1

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

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

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

DS-769 STUN support for intercom devices (Tech preview)

Basic STUN support is added for intercom for peer to peer RTP media between two intercoms that communicate over public PBX.

When STUN is configured to communicate on local network hairpin rules are required on router.

Issues fixed

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.

DS-1633 TCIV+ and TCIS+: New equalizer (EQ) filters for improved audio quality

Created new microphone and loudspeaker EQ filters for all TCIV+ variants, resulting in a more flat frequency response and a reduction of some loudspeaker resonances. This allows for less Acoustic Echo Cancellation (AEC) filtering resulting in improved mic voice signal, and at the same a more pleasant sound quality from the loudspeaker.

DS-1600 Fixed an issue where OLED display text kept scrolling even when scrolling timer was set to 0 on TCIS-4/5 and TCIV-5+

This has been corrected so that the text no longer starts scrolling when the scrolling timer is set to 0.

DS-1568 Fixed an issue where second Permanent Audio Stream (PAS) would not start

The PAS stream 2 under special config page zForm_stream_config should now stream as expected.

Known Issues

MTN-4333 HD-Audio mode not working using digital microphone input

Audio is distorted when digital microphone is used. Audio is OK if using analogue microphone input

+=== DS-1585 Far-End Signal Squelch configuration changes needed reboot to apply===
-==Improvements==
+Now Squelch parameters are applied on the-fly when saving changes.
-=== MTN-4790 Enhanced Grace Period Message for Edge Systems===
-The grace period message has been improved to provide clearer information. Users will now find it easier to understand when their system is in a grace period and if actions are required.
-=== MTN-4701 Duplicate Hardware Version information ===
+=== DS-1516 Relays/outputs can now be triggered by multicast paging streams===
-Duplicate Hardware Version information in station web has been removed. Hardware Version information can be found in Hardware Revision.
+The activation is following the audio stream priorities in the multicast paging.
-=== DS-1560 Edge Controller: Batch Upgrade Feature removed===
+=== DS-1259 In the Hostname field the maximum number of characters is increased to 64===
-The Edge Controller batch upgrade feature has been removed. Batch upgrades should now be performed using IMT, which provides greater flexibility and efficiency. Devices can still be updated individually via the web interface.
+=== DS-769 STUN support for intercom devices  (Tech preview) ===
+Basic STUN support is added for intercom for peer to peer RTP media between two intercoms that communicate over public PBX.
-=== DS-1513 Enabled text rotation on OLED displays for TCIS-4/5 and TCIV-5+ devices===
+When STUN is configured to communicate on local network hairpin rules are required on router.
-Text shown on OLED displays can now be rotated (0°, 90° and 270° increments) for TCIS-4/5 and TCIV-5+ devices

 ==Issues fixed==
-=== 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-4777 The speaker volume is now functioning correctly and retains its settings following a device reboot.===
-=== MTN-4759 Added lua-sec module to the software image, enabling scripts to use SSL functions.===
-=== MTN-4757 The keypad backlight on TEIV-1+ will now be on during the ringing and calling state===
-=== 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===
+=== DS-1633 TCIV+ and TCIS+: New equalizer (EQ) filters for improved audio quality===
-Audio will no longer be interrupted or stopped when unrelated configuration change, such as adjusting the volume, are made.
+Created new microphone and loudspeaker EQ filters for all TCIV+ variants, resulting in a more flat frequency response and a reduction of some loudspeaker resonances. This allows for less Acoustic Echo Cancellation (AEC) filtering resulting in improved mic voice signal, and at the same a more pleasant sound quality from the loudspeaker.
-=== MTN-3887 FPS label on video devices is now shown as Target FPS===
+=== DS-1600 Fixed an issue where OLED display text kept scrolling even when scrolling timer was set to 0 on TCIS-4/5 and TCIV-5+===
-The frame rate setting reflects the intended or target frames per second. However, the actual FPS may vary depending on factors such as encoding conditions, stream configuration, available bandwidth, and image complexity (e.g., high motion or low light scenes). This value is not guaranteed to be constant.
+This has been corrected so that the text no longer starts scrolling when the scrolling timer is set to 0.
-=== DS-1572 Audio Setup Real-Time challenges===
+=== DS-1568	Fixed an issue where second Permanent Audio Stream (PAS) would not start===
-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.
+The PAS stream 2 under special config page zForm_stream_config should now stream as expected.
-=== 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.
