==Release info==
'''Name:''' VSF-Turbine <br>
'''Description:''' VSF-Turbine is a firmware archive for [[Zenitel Devices based on iMX28|Zenitel devices based on the IMX28 processor]].

The firmware is delivered in a ZIP archive:. <br>
'''Version:'''

*'''vsft-6.1.x.x''' - Used for standard in-field upgrades

'''Date:''' 25.05.2021 <br>
'''Status:''' General Availability
'''Compatibility: Pulse to IC-EDGE System'''<br>
You can upgrade from Pulse (VS-IS 4.x) to IC-EDGE, but the whole system needs to run with the same Turbine software (VS-IS 5/6). <br>
In an IC-EDGE System, INCA intercoms cannot be used as the Edge Controller. <br>
TCIV video intercoms should not be used as the Edge Controller for systems exceeding 4 devices. <br>
IMT 1.5 or newer can be used for station discovery and upgrade but must not be used to configure IC-EDGE. <br>
'''Pulse to IC-EDGE Licenses'''<br>
Pulse licenses will be honored in an IC-EGDE System. This means that when you upgrade firmware from VS-IS 4.x to 5.x/6.x your Pulse licenses will work for IC-EDGE. <br>

{{Note|The number of free VS station licenses has been increased from 16 to 32 in IC-EDGE. This means that you get an additional 16 VS stations to connect to in IC-EDGE}}
{{Note|Both Multisite Trunking and VS-Client are free of charge in IC-EDGE}}

==Fixed Issues - Turbine Intercom==
===MTN-3318 Upgrading IP-LCM-A to 6.1.3.0 version causes reboot loop=== 
When upgrading IP-LCM-A station to 6.1.3.0 version, stations is stuck in reboot loop. This is now fixed.

===MTN-3303 Permanent Audio Stream mode: "RTP Stream Always Enabled" made station out of function=== 
If "RTP Stream Always Enabled" the station would not be registered and would not function. This is now corrected, and the station will again be registered and function normally. 


==Known Issues==	
===MTN-3299 TLS Private Keys not restored on Turbine stations=== 
In case that TLS Private Keys are deleted from Turbine station, the only way to restore them is to manually upload them to the station. Factory reset or station upgrade will not restore TLS Private Keys.
		
===MTN-2692 Turbine stations won't register to ICX500 or Alphacom if the dash symbol is not removed from the Directory Number field.=== 
In an unconfigured Turbine station there is a dash character in the Directory Number field in the "Main Settings menu. This dash symbol must be removed when the directory number is entered, else the station will fail to register.
		
===MTN-2686 Outputs not working for Exigo amplifiers in SIP mode=== 
GPO's does not work when exigo amplifiers are in SIP mode.
		
===MTN-2363 Factory reset does not delete uploaded Script=== 
All uploaded scripts should also be removed on Factory reset
		
===MTN-2362 H.264 RTSP stream in UDP mode can display small artifacts at the bottom of the stream=== 
H.264 RTSP stream in UDP mode can display small artifacts at the bottom of the stream.
		
===MTN-2361 TCIV H264 stream does not work in Honeywell Maxpro NVR=== 
RTSP H.264 does not work in Honeywell Maxpro NVR, workaround is to use MJPEG RTSP stream
		
===MTN-2360 Client side forwarding does not work in SIP mode=== 
Client side forwarding, which can be configured as a DAK action or activated from INCA display menu, does not work in SIP mode. Workaround is to use SIP server side forwarding.
		
===MTN-2359 Stream is not always established in Pelco VideoExpert VMS version 3.0 or newer=== 
Stream is not always established in Pelco VideoExpert VMS version 3.0 or newer, workaround is to follow all the steps described here https://wiki.zenitel.com/wiki/Adding_TCIV_ONVIF_camera_to_Pelco_VideoXpert_Professional when adding TCIV station to Pelco VideoExpert
		
===MTN-2358 Making a point-to-point call during High priority Group call will drop group call audio.=== 
When 2 stations establish a point-to-point call during High priority Group call, they will no longer receive audio from current High priority group call.
		
===MTN-2356 SNMP not working properly on TCIV under high CPU load=== 
SNMP is not working properly on TCIV under high CPU load, which means that SNMP traps and inform messages can be sent with delay, or not be sent at all. This only happens if TCIV is placed under very high load, under normal operating conditions SNMP function without any issues.
		
===MTN-2339 Group call chime is not played on 3rd party SIP stations=== 
Group call chime (WAV file) is not played on third party SIP devices when Group Call is set over multicast IP address.
		
===MTN-2220 Default SNMP settings issue with firmware downgrade to 4.9=== 
When downgrading from VSFT 4.11+ to 4.9 a factory reset is necessary if user wants to use default SNMP configuration. For custom snmp.conf file, re-upload with a custom snmp.conf file will fix the problem.
		
===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.

=VSF-TURBINE 6.1.3.0=
==New Features - Turbine Intercom==
===MTN-3144 Third button option for hold state.=== 
Added third button option under Direct Access Keys for managing calls that are put on hold. This option is available in SIP and Edge.

===MTN-3114 Added functionality to force ringing on both accessory and internal loudspeaker=== 
Force loudspeaker ringing option is available in call settings in all modes. It is disabled by default.

===MTN-2956 Whitelist functionality is now added for SIP mode.=== 
If whitelist is enabled on the station callers that are not added to whitelist are rejected.

<br>

==Improvements - Turbine Intercom==
===TYR-109 Security hardening for TLS connections and Secure SIP=== 
Security level set to 112 bits of security. As a result RSA, DSA and DH keys shorter than 2048 bits and ECC keys shorter than 224 bits are prohibited. Any ciphersuite using RC4 is also prohibited. SSL version 3 is also not allowed. Compression is disabled.

===MTN-3093 Improved Tone test to combat noisy environment and to be able to use in places with multiple stations in the close vicinity=== 
Tone volume is automatically adjusted to suit the ambient noise levels and therefore make it suitable to use it in noisy environment. Further improvement is made for environments like a train where multiple stations are next to each other. This might have caused the intercom with faulty speaker picks up tone from another station doing the test at the same time and wrongly reports success. This is now solved by playing multiple frequency tones.

===MTN-2852 Frontboard DAK can now be configured to switch to internal speaker while performing PTT.=== 
This is used as a workaround for issues with headset auto detect. User is able to configure DAK key to send M key as well as switch to internal speaker. This is exposed for TFIX and TFIE stations in call settings of ICX AlphaCom mode.

===MTN-2770 SNMP now allows subnet 32 in allowed network=== 
SNMP now allows subnet 32 in allowed network making possible to limit SNMP traffic to only one IP address.

===MTN-2693 Added call monitoring options=== 
In SIP mode it is possible to configure SIP OPTIONS timer to monitor established calls. If the remote part in a call is unavailable, the call will automatically be hung up. This option is available in advanced configuration mode.
Changed registration handling

The minimum registration time is now 30 seconds. If registration time is configured to be below 60 seconds the registration will fail 15 seconds after initial registration message when the SIP server is not responding.

When station fails to register to a SIP server associated calls which are ringing or queued will now be automatically hung up.

===MTN-2689 Additional information shown for uploaded certificates=== 
Uploaded certificates will now show expiry date, issuer and subject.

===MTN-2661 Options for adjusting CH1 and CH2 offset gain now visible on both normal and extended turbines.=== 

===MTN-1045 Disable scrolling while in call=== 
Stations which have address book and scroll buttons are no longer able to use those buttons while there's an active, incoming or outgoing call.

<br>

==Improvements - Exigo Amplifiers==
===MTN-2694 Support for revert logic handling on ENA 2060's dry contact input=== 
External fault reporting can now be configured to reverse fault reporting logic. Additionally read IP address and disable factory reset are now exposed on station web for Exigo Network Amplifiers.

<br>

==Fixed issues - Turbine Intercom==
===MTN-3231 Address book is not downloaded with .csv extension.=== 
When you would download address book it would download as .txt. Now this is fixed.

===MTN-3057 Group Calling in Sipelia=== 
Video will now stream when Group Call in Sipelia is established.

===MTN-2836 TFTP provisioning would sometimes look for wrong filename if SIP domain was not configured=== 
TFTP provisioning would sometimes look for wrong file with IPv6 address instead of IPv4 address if the primary SIP domain was not configured. This has been fixed.

===MTN-2824 Audio Messages - station offline message not played=== 
Offline message would not be played, this has been fixed.

===MTN-2823 Call is now terminated in exactly 40 seconds if other party is unavailable.=== 
Before, detection period using the SIP OPTIONS, of other device going offline was random and up to several minutes based on device MAC.

===MTN-2820 Mobile app crash during QR code scan=== 
Bug fix for mobile app crash during QR code scan caused by empty item in Global Address list.

===MTN-2814 Offset gain applied was applied wrong=== 
Offset gain was applied wrong, causing it to be much higher than it should be

===MTN-2795 Audio stops working=== 
If the station detects audio issues, the audio driver will be reset. This might cause a 1 second drop in the audio.

===MTN-2794 Edge controller parallel ringing ringlist configuration is now working correctly.=== 
Before there was issue where saving buttons on a station over Edge controller would reset parallel ringing configuration used when calling ringlist for that particular station. Workaround was to save ringlist settings on Edge Controller again.

===MTN-2777 Line out audio distorted when more than 6dB CH2 gain applied=== 
When more than 6dB Volume CH2 (gain) was applied audio was distorted because gain jumped to 24dB regardless of value. Volume CH2 (gain) should now follow set value.

===MTN-2774 Properly show values in Manual Time configuration=== 
Values for Manual Time configuration are now properly shown and are not only partially visible.

===MTN-2759 Missing pages in station web for ICX-Alphacom mode=== 
Web configuration pages

*Backup and restore
*Logging

are now visible in ICX-Alphacom mode again.

===MTN-2755 Mobile app loses registration after Edge Controller reboot=== 
When Edge Controller is rebooted mobile app would lose registration after 10 minutes, if app was not active in that time frame. This has now been fixed.

===MTN-2677 Call forwarding not working for stations registered to Alcatel SIP servers===
On Alcatel SIP servers when a Zenitel station tried to call a station which had call forwarding active, the call failed. This is now fixed.

===MTN-2663 Video lost on TCIV in some rare cases=== 
In some rare cases video can be lost on TCIV produced in 2019 and earlier. If this happens the TCIV needs to be replaced. This issue cannot occur if upgraded to latest software image.

===MTN-1466 Cannot save firewall settings for same port with different protocols=== 
It was not possible to save firewall settings if rules with the same port number but different protocols (for example port 5060 which has rules for tcp and udp) were edited. This is now fixed.

===SUN-545 Proper default ANC, AGC and AVC values when configuring the system from Edge Controller===
Edge Controller was pushing old default values for ANC, AGC and AVC to the stations, this has been fixed.

<br>

==Fixed issues - Exigo Amplifiers==
===MTN-2972 SNMP daemon uses too much memory when SNMP traps are enabled=== 
When SNMP traps (notifications) are enabled snmpd uses too much memory since it stores 1000 last traps with 24h timeout in log. This has been reduced to 10 traps with 1 hour timeout
	
===MTN-2739 Amplifier Class D chip may crash when analog bypass is used=== 
When analog bypass is used on ENA2200/ENA2400, audio filters were not active which could cause Class D chip to crash. Analog bypass is now changed to Digital (SW) bypass that applies audio filters

In Exigo Management Tool, the Amplifier output channel setting "HW Bypass Mode" on all ENA amplifier types is renamed to "Bypass Mode".

Also, the Bypass Mode can now be set individually for each Amplifier output channel on all ENA device types.

<br>

==Known Issues==
===MTN-3303 Permanent Audio Stream mode: "RTP Stream Always Enabled" make station out of function=== 
If "RTP Stream Always Enabled" the station will not be registered and will not function. Using "RTP Stream Enabled During Call" will work.
