Improvements

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

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

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-1513 Enabled text rotation on OLED displays for TCIS-4/5 and TCIV-5+ devices

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

Subscription requests now accept any namespace in the Address field.

The “wsnt:Filter” element is now optional. If omitted, the subscription will include all topics by default.

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

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.

MTN-3887 FPS label on video devices is now shown as Target FPS

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.

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.
