2N OS version 2.50.0 for 2N Intercoms includes the following changes
Precautions to be taken during update to FW version 2.50.x
- For security reasons, network settings can no longer be modified using 2N Network Scanner.
- All 2N OS devices (except those on the original platform: IP Vario, IP Force, IP Safety, IP Solo, IP/LTE Verso, IP Base, IP Uni, IP Audio Kit, IP Video Kit, Access Unit, SIP Speaker) can no longer be downgraded below version 2.47.0 after updating.
- Devices no longer accept certificates signed with 1024-bit RSA keys. These certificates are removed during the update and must be replaced with certificates using at least 2048-bit RSA or ECC keys. Services relying on weaker certificates will stop functioning, and a warning will appear next to the certificate selection parameter in the web interface.
- In EAP-TLS mode, 802.1x no longer supports RADIUS certificates containing the `id-kp-clientAuth` Extended Key Usage. If such certificates are used, they will be rejected after the update, resulting in the device being unable to authenticate and connect to the network.
- Due to essential authentication updates for an improved user experience, you must restart the ACS server to restore connectivity for devices upgraded from a version lower than 2.49.0 to version 2.49.0 or higher.
New Functions and Improvements
- Reception of `In-Band (Audio)` DTMF is now disabled by default to improve resilience against malicious attacks.
- STUN support has been added and can be configured under `Calling > SIP # > Configuration`.
- Added support for the Japanese language in the display UI of Answering Units and IP Style.
- Support for 2N Electronic Locks is now included as part of the standard firmware release.
Essential Corrections
- Improved compatibility of outgoing H.264 and H.265 video streams.
- Private keys are no longer exposed via `GET /api/mobilekey/config`.
- Updated several internal libraries.
- Web configuration pages for Automation features now load correctly even when the device is offline (without an active internet connection).
- Eliminated occasional audio distortions on IP Uni and IP Audio Kit devices.
- Fixed an intermittent issue where audio inputs could become swapped on IP Uni and IP Audio Kit devices.
- Devices no longer crash when a user with a limited validity period presents their card, provided the associated RFID reader extension module has `Door` set to `Not used`.
- Cached DNS entries for SIP registrars now expire immediately and correctly when the registrar IP address changes, preventing registration failures.
- Fixed an issue where devices could lose and reacquire their IP address via DHCP twice after a factory reset and subsequent reboots.
- Resolved a device crash that could occur when sending emails using specific SMTP server configurations.
- The `snmpget` function now works correctly on devices using SNMPv3.
- Devices now correctly process `Too Brief` SIP responses during registration and immediately apply the updated expiry period.
- Fixed device crashes caused by specific malformed or non-standard ONVIF requests.
- Corrected an issue where video resolution could be incorrectly limited when selecting lower bitrate settings for the H.265 codec.
- Added a limited-range mode to the WaveKey opening algorithm to prevent unintended door openings from excessive distance.
- PEAP MSCHAPv2 authentication is now fully functional and reliable across all supported models.
- Eliminated a condition that could cause SIP registration to become permanently stuck in the unregistered state.
- Other corrections and fixes.
