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

Release info

Name: VSF-Fortitude Audio Only
Description: VSF-Fortitude Audio Only is a firmware for Zenitel devices based on the IMX8M Nano processor.

Improvements

DS-1517 Unconfigured IP speakers now announce their own IP address at startup

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-1366 ZIPS devices now have a tone test that test the speaker/mic connection and the amplifier circuit.

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.

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

 == Improvements==
-=== MTN-4701 Duplicate Hardware Version information ===
+=== DS-1517 Unconfigured IP speakers now announce their own IP address at startup===
-Duplicate Hardware Version information in station web has been removed. Hardware Version information can be found in Hardware Revision.
-=== DS-1560 Edge Controller: Batch Upgrade Feature removed===
+=== DS-1516 Relays/outputs can now be triggered by multicast paging streams===
-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.
+The activation is following the audio stream priorities in the multicast paging.
+=== DS-1366	ZIPS devices now have a tone test that test the speaker/mic connection and the amplifier circuit.===
+=== DS-1259 In the Hostname field the maximum number of characters is increased to 64===

 == 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-4769 It is now possible to play Audio message on triggering Relay or Output ===
-It is now possible to play an audio message when triggering a Relay or Output. Previously, nothing was shown when selecting Relay for an Event under Audio Messages. Relay and Output are now available for selection.
-=== MTN-4742 ONVIF Improvement: Default Video Source Configuration===
-GetVideoSourceConfigurationOptions now returns a default video source configuration even when no configuration is specified.
-=== MTN-4717 Volume Override Level and Automatic Volume Control (AVC) configuration ===
-Volume Override Level and Automatic Volume Control (AVC) configuration on IP Speakers (ZIPS) are now configurable from the Edge Controller
-=== 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-4656 Fixed numbers of GPIOs for configuration===
-GPIOs were available for configuration, while IP Speaker has one GPIO. Now only one GPIO is shown for configuration.
-=== MTN-4655 GPIO is now shown as Relay if set as Output===
-If GPIO was set as Output under I/O tab, it was not shown as Relay under Relays/Outputs tab. This is now fixed.
-=== 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-1502 Multicast paging could stop working under some rare conditions===
+=== DS-1568 Fixed an issue where second Permanent Audio Stream (PAS) would not start===
-Multicast paging would stop working under some rare conditions, this is now fixed.
+The PAS stream 2 under special config page zForm_stream_config should now stream as expected.
