New Features - Turbine Intercom

SNOW-577 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-278 IP Multicast audio support for SIP Intercom

Turbine and INCA IP intercom stations now support IP multicast audio when configured in SIP mode. Up to 10 multicast IP addresses can be configured.

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-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.

SNOW-109 ECPIR panels - Led dimming minimum brightness

ECPIR panels can now set minimum brightness for LED using StationWeb. This resolves issue when operator could dim LEDs to low so it looked like the panel is not working.

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)

New Features - Exigo Network Amplifiers

SNOW-177 Exigo Network Amplifiers: StationWeb new options

• Configuration of the Exigo Network Amplifiers can now be done via the web pages when the amplifier is in Alphacom mode.
• Live view of state is available through the web.

SNOW-141 Exigo Network Amplifiers: Line input forwarding

• Line input off amplifiers can now be routed directly to the output channel without a server being available
• When Line Input Forwarding is enabled, no audio is received from the server - only local audio is allowed

SNOW-103 Exigo Network Amplifiers can be connected to Alphacom systems

• VSFT-Turbine software can now be used on Exigo amplifiers. This allows the amplifiers to be connected directly to Alphacom systems.
• Each amplifier channel will behave as an IP station with all features available
• Channel 2 can mirror channel 1 so that only one license and directory number is used
• Monitoring of the amplifiers is available via the Alphacom event handler and syslog
• Function requires AlphaSys version 12.5.2.0 or later
• Sip and pulse is not supported on Exigo amplifiers

MTN-1690 G711 is now supported in Exigo

Audio engine on all devices now support G711 which is sometimes used for SIP integration

Technical Preview - VSF-Turbine 4.9.3.0

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

Bugfixes and Improvements - VSF-Turbine 4.9.3.0

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

Turbine sends UDP SIP even though configured to use TCP. Fixed

SNOW-333 Warning for TCIV as Pulse server

New warning added on StationWeb: It is recommended not to use TCIV as Pulse server in a systems with more than 5 registered clients. For such systems please use any other Vingtor-Stentofon IP station type, such as TCIS-x, or TKIS-2.

SNOW-245 Remove Enable full audio output setting from web

The reason this flag was added is because we removed the far end anti clip filter, which caused the station to reboot easily if the received signal was clipped. Now we have enabled anti clip filter and DRC by default - the station will not reboot anymore even if it’s powered from PoE.

SNOW-244 Expose TFIE-6 menu settings on station web

Now all TFIE-6 menu settings are also available on StationWeb.

SNOW-88 Enable all DAK actions for all Turbine stations

All DAK actions are now enabled for all Turbine stations, not filtered anymore by station type.

MTN-1785 Upgrading stations using Pulse Server not working if TFTP server is on another subnet

Fixed.

MTN-1757 Serial registration method does not display correct status

Fixed with displaying proper registration status on StationWeb info Page.

MTN-1432 TFIE-6 Address book- Dir. number not displayed and entries are not in order

Fixed with showing Dir. number and also added options to order by Dir. number or Label/Name (TFIE-6, TCIS-6, TCIV-6)

MTN-1236 TCIS-6 Address book does not support national characters

Fixed with added support for international non-English characters.

MTN-618 Turbine station does not send ARP update during startup.

Replacing a faulty station with static IP address with an identical configured station must wait for the ARP tables of the switches to timeout before register at AlphaCom. This is now fixed with sending ARP update during startup.

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

Characters like !#$%&/()=@* are now handled in the password input field for 802.1x.

Known Issues - VSF-Turbine 4.9.3.0

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

More than 12 characters entered causes registration problems

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

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-268 Relay follow M-key cannot handle quick M

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

MTN-1503 Changing the Detailed Logging setting disables syslog logging

If Detailed Logging is enabled or disabled, the syslog functionality doesn't work - Turbine log messages do not arrive on the syslog server. Workaround: Changing Log level setting for syslog will enable the syslog logging again

VSIS-878 Factory reset does not delete uploaded Script

All uploaded scripts should also be removed on Factory reset

SNOW-579 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

MTN-2020 Acoustic Echo Cancellation performance issues

Compared to earlier versions it is observed more echo artifacts, and in some cases full echo return.
Note! When using a Turbine on the maximum gain level in Full Open Duplex, some echo artifacts may occur. This depends on many factors like the station mechanics, the mounting, the tone and level of Far-End audio talker etc.
