Improvements
DS-1910 Deprecation Notice for Legacy ENA Amplifiers
VS-IS 9.6.3.0 is the last supported firmware release for ENA2100-AC (Item No. 1023102100) and ENA2200 (Item No. 1023102200).
DS-1879 Acoustic Tuning & Echo Suppression Improvements
Updated acoustic filter profiles for TMIS station to minimize resonance, suppress echo artifacts, and deliver clearer speech intelligibility during open-duplex calls.
DS-1875 Acoustic Tuning & Echo Suppression Improvements
Updated acoustic filter profiles for VR3G-1 and VR3G-1P stations to minimize resonance, suppress echo artifacts, and deliver clearer speech intelligibility during open-duplex calls.
DS-1872 IPVRS Improved audio frequency response on Mic and Loudspeaker signals
Audio tuning updates have been introduced on the IPVRS to improve speech intelligibility, reduce distortion, and enhance audio switching performance. These improvements deliver a clearer, more natural voice experience in both half-duplex and open-duplex communication.
DS-1671 Acoustic Self-Test Support for IPHDT Handset Stations
Added automated audio tone testing for IPHDT handset stations. The test verifies acoustic integrity between the earpiece and handset microphone, running strictly when the handset is cradled and the station is idle.
Fixed issues
DS-1985 Corrected Maximum Output Volume on IPVRS Stations
Resolved an issue where maximum loudspeaker output on IPVRS stations was lower than specified. The volume range has been corrected to deliver full acoustic output for both standard voice calls and volume override announcements.
DS-1905 Multitone tone test robustness adjustments
Adjusted thresholds for tone FFT bin magnitude feedback from speaker to mic to reduce false negatives in moderate to high noise.
DS-1903 Security Update
Resolved vulnerabilities related to: CVE-2026-95379 Path traversal in certificate deletion API.
- Action: Upgrade to 10.1.3.0 or later
DS-1902 Security Update
Resolved vulnerabilities related to: CVE-2026-95378 Path traversal in certificate upload.
- Action: Upgrade to 10.1.3.0 or later.
DS-1901 Security Update
Resolved vulnerabilities related to: CVE-2026-95377 OS command injection via DHCP provisioning.
- Action: Upgrade to 9.6.3.0 or later for SIP, IC-Edge and ICX-Alphacom, and 10.1.3.0 or later for Zenitel Connect.
DS-1855 ONVIF authentication occasionally failed after device boot
WS-Discovery advertised the ONVIF service before all user accounts were initialized, causing authentication attempts made too early in the boot process to fail.
DS-1844 Bottom pixels on TCIS-6 and TCIV-6+ do not scroll with the other text
Bottom pixels on scrolling stations are now correctly updated
DS-1843 Delay at about 350-500 ms delay when switching speech mode from Listen (send mic audio) to Talk (Play On speaker)
Fixed time delay issue when enabling the Loudspeaker in cases where speaker was fully muted (mic only) and switching back to loudspeaker active. This delay was first introduced on SW version 8.2.3.0.
