Turbine 4.9 - Release notes

VSF-Turbine 4.9

Release info

Name: VSF-Turbine
Description: VSF-Turbine is a firmware archive for all Turbine Family Intercom stations including devices: TCIS-x, TKIS-2, TCIV-x, TMIS-x, TFIE-x, TKIE-x, TFIX-x, ECPIR-3P and Exigo IP speakers.. The firmware is delivered in two different ZIP archives:

• sti-4.9.3.x - Used for standard in-field upgrades
• sti-prod-4.9.3.x - Used in production and recovery upgrades

Version: 4.9.2.2
Date: 20.03.2018
Status: Limited Availability

New Features 4.9

SNOW-103 Exigo Network Amplifiers can be connected to Alphacom

• ENA2100-AC, ENA2200, ENA2400-AC, ENA2400-DC can be connected directly to AlphaCom
• Each amplifier channel will behave as an IP station with all features available
• Monitoring of the amplifiers available via the Alphacom event handler and syslog
• Function requires AlphaSys version 12.5.2.0 or later

SNOW-250 Advanced Turbine AVC settings on StationWeb

Exposed advanced AVC settings like thresholds, attack and decay rates, lockout time, etc. on Turbine StationWeb for AVC algorithm parametrization. These options should be used only in case when default AVC behavior needs to be fine tuned and when technician has good understanding about the AVC technology.

SNOW-87 Virtual I/O script on DAK event with reading GPI status

Now we can enable/disable DAK key action (e.g. make call) according to state change on certain GPI. Use case: disable intercom for non-authorized personnel using badge-reader, deny intercom call without vehicle in front of the station (detected by a loop into the floor)

Technical Preview

VSIS-865 Digital Audio Squelch on Far-End audio

New function for silencing audio to be played to speaker, if signal energy is below a configurable threshold level. This can be used to suppress noise when below-desired-level signal is present.

SNOW-229 Secure SIP and Secure RTP for Turbines in SIP mode

Added support on Turbines for SIP over TLS. SIP over TLS encrypts the transport layer using the same method as HTTPS which uses certificates to validate the server. In addition, the Turbines now support SRTP which brings encryption to RTP media (call audio). This means that now both call metadata and call media can be fully encrypted. Note: TCIV H.264 is not supported with SRTP

SNOW-191 Support SIP Early Media during 180-Ringing or 183-Session Progress

Support playing a media during SIP 180-Ringing or SIP 183 Call progress, instead of a locally generated ringing tone. This is a very common setup in iPBX systems where server shall generate a media to be played during session progress and before call is accepted (e.g. Call queued before answered). Note that we do not fully support RFC3960.

Bugfixes and Improvements 4.7.3.2 (GA)

MTN-1419 Turbine sends 5 identical SIP Register messages towards iPBX

This can potentially cause issues (e.g. SPAM filtering) on Alcatel OXE 12.0 or latest Asterisk. Improvement implemented.

MTN-1737 Turbine can have registration issues when using TCP Outbound transport

If there was an unsuccessful registration with 3rd party iPBX when using TCP Outbound transport type, the Turbine would not be able to re-register without a reboot. This is now fixed.

MTN-1739 Turbine stations configured with SIP TLS may start replying to wrong port (5060)

If the record-route header did not specify a port or sips scheme, port 5060 was used to send requests while the record-route indicated transport type TLS which should default to port 5061.

MTN-1666 Periodic sound loss when doing announcements using relayed multicast

Improved the Relayed Multicast handling to be more robust on larger systems.

Security and Improvements 4.9.2.2 (LA)

None

Known Issues 4.7.3.0

MTN-268 Relay follow M-key cannot handle quick M

Relay configured to follow M-key does not handle quick press on M-key

MTN-323 Noise from wind on TCIS

Wind may cause powerful acoustic signal on mic that software is not able to filter and at same time keep clear voice. Workaround is to make mechanical filtering or shielding of wind effect on mic.

MTN-408 802.1X config not properly handling special characters in password

Character like % is not handled in the password input field for 802.1x.

MTN-552 PULSE: (Re)Registration of SIP phones takes a long time

Long (re)registration times observed on Divus SIP client and SNOM phone. If the same SIP phone is registered against AlphaCom the process is almost instantaneous.

MTN-598 INCA station fails to register if Hebrew name is too long

More than 12 characters entered causes registration problems

VSIS-878 Factory reset does not delete uploaded Script

All uploaded scripts should also be removed on Factory reset

MTN-1073 Group call fails if system previously configured with ZAP

If system was configured with ZAP (VS-IMT Pulse SDK project) and then switched to XML configuration by deleting data.lua file, it is possible that Group Calls shall not work. A workaround is that (1) data.lua file is deleted from all stations including Pulse server - this will reboot stations, and (2) after reboot go to Server configuration -> Save + Apply - this will again reboot all stations.

MTN-1077 Lamp test not functioning on ECPIR-3P and belonging EBMDR-8

Alphacom DAK Lamp test (feature 7874) not implemented on DAK Panel ECPIR-3P and belonging EBMDR-8

VSIS-1202 TFIE-6 does not display AlphaCom status-messages in Idle

There is no way of knowing if a TFIE-6 is for example forwarded(71,72) or marked absent(77x). Workaround: During commissioning it is possible by Class Of Service programming in AlphaCom to deny access to these services for the TFIE-6

VSIS-1207 Turbine Tone test requires restart to enable it after being disabled

Turbine tone test is disabled by default. If it is enabled and later on disabled, it will require station reboot to enable tone test again. Workaround: Tone test started to work again after rebooting the station.

VSIS-1214 Turbine sends UDP SIP even though configured to use TCP

Turbine sends UDP SIP even though configured to use TCP. Workaround: configure Outbound Proxy to have the same value as Server Domain.
