Technical Preview

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

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.

Bugfixes and Improvements (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.

Bugfixes and Improvements

MTN-1438 Handling NAND Flash in Production

Due to problem with certain flashes a new Flash Partition Layout was required.

VSIS-1155 During upgrade process station can end up in reboot loop if firmware files not transferred successfully

Firmware upgrade procedure is made more robust and all firmware image files are checked for successful transfer before flashing procedure is started.

Bugfixes and Improvements (GA)

VSIS-1146 Turbine and INCA fail in AlphaCom with Relay Multicast

Multicast fails when Turbine and INCA listen to audio program over Relayed Subnet (AlphaCom environment)

VSIS-1222 Internet Explorer had issues with properly handling dynamic UI controls

Introduced better javascript handling so that all HTML components are properly rendered in IE

VSIS-1196 Answer Group Call doesn't work with Answer Call function

When Answer Group Call is used with Answer/End Call action it works OK (workaround).

VSIS-1211 Multiple MJPG streams in browser causes poor TCIV audio quality

With multiple MJPG streams open in different browsers, we can have poor audio quality because the CPU is very high. Fixed with limiting number of 240p streams to 3 (from 4).

VSIS-1230 TCIV limitations with PAS and MJPG clients

Available number of Permanent Audio Streams on TCIV has been decreased to 1. If PAS is enabled on TCIV, number of available MJPG clients will be decreased by 1 as long as PAS is enabled. This means that limitations are 1 MJPG client for 480P, and 2 MJPG clients for 240P.

Bugfixes and Improvements (LA)

MTN-696 Selectable group call chime in Pulse

In order to use the group call functionality for broadcasting messages through PTT the chime must be possible to deactivate or disabled during such an announcement

MTN-845 Turbine with Static IP failed to upgrade from different subnet

When Turbine is set with static IP address the upgrade will fail when IMT or TFTP server is located in different LAN subnet. This is now fixed with proper gateway handling in barebox (bootloader) environment. NOTE: Upgrading the bootloader is done from the Station web page, "Station Administration" > "Manual Upgrade", enter Image file: boot/sti- ("boot/" being a prefix in front of the file name).

MTN-890 VAD control from AlphaCom through $DIP doesn't work on Turbine


MTN-918 "Line out source: Microphone" setting does not work, option is missing in SIP/Pulse


MTN-1049 Relay idle setting doesn't take effect immediately

Previously uploaded security certificate is being removed with firmware upgrade. For station to successfully authenticate toward 802.1x AAA server, the certificate will need to be uploaded again.

MTN-1165 Wrong MAC shown after loading XML backup on Turbine

Fixed for Turbine. MAC address, host name, hardware type and frontboard (if factory set in /goform/zForm_fact_set) will be correctly set after restore of config file.

MTN-1196 TCIV rebooting when connected to CCTV server

Implemented solution to prevent more then 4 client connections for MJPEG stream 240p and more then 2 for 480p.

MTN-1230 Multicast for Turbine Stations with onboard switch (TFIE, TKIE and ECPIR) fails

Repaired multicast handling in networks that do not have an IGMP querier.

VSIS-318 License grace period expiration warning on StationWeb

Warning is displayed on station web under server monitoring and licensing. Remaining days of grace period are displayed.

VSIS-704 Group call should use caller codec

Only the g722 codec was supported before, so now the call codec is taken from caller

If camera module upgrade took longer than 1 minute, TCIV station ended up in reboot loop. This is now fixed.

VSIS-819 Hide unsupported DAK functions on substations

DAK functions which are not supported on substations are no longer shown.

VSIS-1158 TMIS Factory Reset from Frontboard

Key scanner chip was reset after factory reset key press detection

VSIS-1162 Disable Call functions on DAKs when Idle function does not support it

Certain Idle functions do not allow Call function to be set on DAK. For those functions, Call functions are now disabled in station web.

VSIS-1163 Turbine in SIP/Pulse mode does not read ipaddress if DAK is set to call ringlist

The turbine station will now read ipaddress if the station is not registered and the ringlist is not a direct ip call (configured to call number@ipaddress).

VSIS-1165 Added Video setup mode - Cisco

Cisco phones have issue when sending less then 25 fps. Now users can select Cisco mode on StationWeb and video will always be sent in 25 fps. In that case fps parameter on StationWeb will just be related to how many images will be different

VSIS-1172 ECPIR-3P DAK LED notification has been improved

See documentation for more details

VSIS-1173 TCIV Video is now enabled by default

Mode is MJPEG with 480p and 15fps.

Known Issues

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.
