MTN-4004 Added support for more complex passwords

Passwords can now be 32 characters long, numbers, letters and the following special characters are supported ?!@$*,.- The password must meet the following criteria:

  • Minimum length of 8 characters
  • At least three out of the following four requirements must be met:
    • Contains at least one digit (0-9)
    • Contains at least one uppercase letter (A-Z)
    • Contains at least one lowercase letter (a-z)
    • Contains at least one special character

MTN-3259 Added option to make device ringlists independent of Edge Controller ringlist updates

When ‘No updates from Edge Controller’ checkbox is enabled, the ringlist is managed locally in the station. Global ringlist configuration in the Edge Controller is then ignored.

MTN-3981 Now possible to disable microphone in IP speakers

Now the microphone input can be disabled in configuration “Audio Input Terminal”/”Internal Mic” with option “Not Connected”. The default configuration for the microphone is ‘enabled’. Note! The Tone Test will not work when the microphone is disabled.

DS-564 VSFT Devices with accessory configuration - Internal Loudspeaker Gain affected by Line Out Gain

There was a dependency between gain controls for different audio outputs. On default configuration levels (0 dB) the Internal Loudspeaker was -4.5 dB compared to the target level (65 dBA at@0,5m and nominal signal). Adjusting the Line-Out Gain would further impact the Speaker output level. The gain controls are now independent.

DS-463 Reduce VoIP delay for PAGA-interface

Targeting Kits being a VoIP gateway from analogue systems, the possibility to reduce the digital signal delay by turning off all digital Voice Processing is added. Use “Advanced Audio Config” / “Audio Signal Processing” and turn off all processing blocks. This will reduce latency with about 60 ms. Furthermore to reduces latency disable “RTSP and ONVIF” on both sender and receiver end (when not being an ONVIF enabled system). This can reduce end-to-end delay with 20-30 ms more. Also some improved receive JitterBuffer handling should ensure lower latency. In total end-to-end latency should be down to 50-60 ms with all measures above active.

Fixed Issues

MTN-4061 Digital/analog mic switching on TCIS works only when input 5 is used

Now the input pin number 1-6 to use is read from config under “Audio Input Terminal”/”Internal Mic”

MTN-4056 It's now possible to disable OPTIONS timeout in Edge mode

Added a text field to disable or change the timeout for SIP OPTIONS when in Edge mode. Setting the timeout to 0 disables it. This option is analog to the one provided in SIP mode.

MTN-4000 RTSP can now be enabled or disabled

RTSP stream can be manually enabled or disabled (it's enabled by default), when disabled all RTSP related settings get grayed out (disabled).

Known Issues

MTN-4049 IP Heavy Duty Telephone shows speaker volume setting when in Edge Controller mode

IP Heavy Duty Telephones do not have a speaker, this has been disabled in the device model. The setting option in Edge Controller mode does not do anything and should be ignored

MTN-3489 Downgrading IP_LCM from vsft- will cause a reboot loop

If downgrading the IP_LCM from vsft- to an earlier version, the IP_LCM will go into a reboot loop. Workaround is to factory reset the IP_LCM just after downgrading.

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 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.
