2N OS version 3.0.0 for 2N Elevator Systems includes the following changes
Precautions to be taken during update to FW version 3.0.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.
New Functions and Improvements
- Reception of `In-Band (Audio)` DTMF is now disabled by default to improve resilience against malicious attacks.
- Default values and ranges for `Calling > Alarm Call > Test Alarm` parameters have been updated. `Enable` is now set to TRUE by default, and `Press Duration to Activate` now accepts values from 5 to 60 seconds.
- STUN support has been added and can be configured under `Calling > SIP # > Configuration`.
- The custom language name defined in the translation file is now displayed in the Display UI instead of the generic "Custom" label.
Essential Corrections
- Updated several internal libraries.
- Web configuration pages for Automation features now load correctly even when the device is offline (without an active internet connection).
- 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.
- Other corrections and fixes.
