v. 2.0.42.768


1 Firmware Pack

The firmware pack is a ZIP file that contains the modules and the features to install on your Mediatrix unit when a new release is available.

When unzipping the firmware pack, the content is extracted according to a pre-defined tree architecture. This creates a directory that contains the files required for the Mediatrix unit to properly upgrade its firmware.


2 New Functionalities


Incident #CR #SynopsisApplies To
Description
---DGW-7879The virtualised network adapter must be configurable in the Virtual Machine.VM

The virtualised network adapter is now configurable via the VM service. The default choice is the Intel 82540em (a.k.a e1000), and if the OS supports it, it can be configured for "virtio-net" (a.k.a. virtio)

IN-12889

DGW-7682Add FXO port calibration customisation.FXO

It is now possible to adjust the digital hybrid coefficients for FXO telephony cards.

The Pots.FxoCustomBasicParameters[Id=FXO].DigitalHybrid parameter was added to allow the configuration of the digital hybrid coefficients for FXO telephony cards. This new parameter is not available in the DGW Web interface. This new parameter will only be applied if the Pots.FxoCustomBasicParameters[Id=FXO].OverrideDefaultCountryParameters parameter is enabled.

IN-13099

DGW-7259Create a virtual network interface, independent of a physical ethernet port (i.e. not bridged) to enable communication between the host and the VM(s) instance.VM

A virtual network interface can now be added to the host to enable communication between

  • the host and the VM(s) or
  • one VM to another

The interface uses a specified IP address from the provisioning. Two new parameters were created:

  • InternalVirtualSwitchEnable: specifies if an internal virtual network interface should be created between the VM(s) and the host.
  • InternalVirtualSwitchIpAddr: specifies the IP address and subnet mask to use on the host.

IN-12528

DGW-5539Add an interoperability parameter to send a 183 with SDP before sending a 180 on FXS endpoints.all

The SipEp.InteropSend183WithSdpBefore180 interoperability parameter was added to send a 183 with SDP before sending a 180 on FXS endpoints.

The feature is disabled by default and can be activated via the SipEp.InteropSend183WithSdpBefore180 parameter. This parameter is not available in the DGW Web interface.

---DGW-3460Add new diagnostic log file troubleshooting feature.all

This feature enables the collection of data analysis information into a compressed archive after a system interruption or on demand via the new diagLogAutomaticDump parameter.This parameter can also disable the diagnostic file log generation after a system interruption. Depending on the unit, it may take several minutes for the generation of the diagnostic log and therefore restarting the unit make be longer after a system interrupt. The new diagLogAutomaticDump parameter is available in the DGW Web interface under System/Diagnostic.

The result of the generation of the diagnostic log file is a tar compressed file containing system information files such as disk space usage, unit info, uptime, and the system RAM. On some plat-form the core dump might be present.

IN-13122

DGW-7092Allow ISDN switches to use logical numbering instead of the ISDN standard numbering.PRI

The new InteropConsecutiveChannelIndicator interop parameter allows the ISDN service to send the channel indicator in consecutive logical numbering instead of physical numbering as it should be. The parameter can have two different values:

  • enabled: numbering goes from 1 to 30
  • disabled: numbering goes from 1 to 15 and 17 to 31. IMPORTANT: The new InteropConsecutiveChannelIndicator interop parameter should NOT be enabled except when the other side of the ISDN line is known to not follow the ISDN specification.

IN-12842

DGW-6924SIP Signalling is not handled properly by QoS.Lldp

When the network policy for the specified application type is unknown, the VLAN ID, the Layer 2 priority, and the DSCP value fields will be ignored.

---DGW-3460Add new diagnostic log file troubleshooting feature.all

The manual diagLogAutomaticDump parameter was created to manually enable/disable the collection of information files into a compressed archive for later analysis.The new diagLogAutomaticDump parameter is available in the DGW Web interface under System/Diagnostic.



4 Issues Fixed


Incident #CR #SynopsisApplies To
Description
---DGW-7901Access to deprecated Isdn.PrimaryRateInterface.LineType parameter via the CLI or configuration script are not working.all

The access to the deprecated Isdn.PrimaryRateInterface.LineType parameter via the CLI or configuration script is now correctly redirected to the Hardware.Ports.LineType parameter.

IN-13221

DGW-7523Unit does not send DTMF in RTP media if a re-INVITE is received between the DTMF start and the DTMF end.all

This scenario occurred when the Key Press Stimulus (KPML) feature was used to initiate telephony supplementary services such as hold/resume.

The DTMF NOTIFY for KPML is now sent after the DTMF end reducing the occurrence of the problem

IN-13180

DGW-7406Monitoring and Blacklisting parameters in the Sbc Call Agents are not retained when "cancel modification" is used.Sbc

When a Call Agent is modified or deleted and if the "cancel modification" is used, the Monitoring and Blacklisting sections are now restored.

---DGW-7308Conference calls may fail when processing many calls and when more than one conference call is hosted on the unit.all

Conference calls on the Mediatrix S7/G7 series and the Sentinel 100/400 units with more than one DSP could fail even if the unit had sufficient resources. Conference calls no longer fail.

---DGW-7287The connection to upload a file in HTTPS was accepted using a TLS version lower that the one configured.all

TLS minimum version was only enforced in downloads. It is now enforced both in uploads and downloads.

---DGW-724890-second delay when unit receives a restart on channel 16.PRI

When the unit received an unexpected ISDN Restart on channel 16, D Channel, there was a 90-second delay before the unit continued to respond to the next restart. The unit now ignores restarts on channel 16.

IN-12842

DGW-7098When a call is forked and a re-invite is sent to renegotiate the SDP the call closes.all

The call no longer closes when a call is forked and a re-invite is sent to renegotiate the SDP.

IN-13122

DGW-7092Allow ISDN switches to use logical numbering instead of the ISDN standard numbering.PRI

Some ISDN switches use a logical numbering from 1 to 30 for the timeslots instead of the ISDN standard physical numbering from 1 to 15 and 17 to 31 bypassing the signaling timeslot 16 which must not be used for data transmission. The new InteropConsecutiveChannelIndicator interop parameter was added to use the logical numbering scheme instead of the ISDN standard. When enabled, this new interop parameter allows the ISDN service to send the channel indicator in consecutive logical numbering instead of physical numbering as it should be. The parameter can have two different values:

  • enabled: numbering goes from 1 to 30
  • disabled: numbering goes from 1 to 15 and 17 to 31. IMPORTANT: The new InteropConsecutiveChannelIndicator interop parameter should NOT be enabled except when the other side of the ISDN line is known to not follow the ISDN specification.
---DGW-7031A Virtual Machine can use more storage than capacity configured in Vm service.VM

A Virtual machine can no longer be created with a disk capacity higher than the disk capacity configured in VM configuration file.

IN-13098

DGW-6932ISDN channels remain in maintenance state following ISDN restart procedure.Isdn

When the Isdn service is restarted, the Restart messages are now handled properly if channel numbers span across multiple information elements. Therefore, ISDN channels no longer remain in maintenance state if the Isdn service is restarted.

IN-12842

DGW-6924SIP Signalling is not handled properly by QoS.Lldp

After discovering the VLAN ID from the LLDP, SIP Diffserv flags were not tagged correctly causing the signaling policy to be wrong. When the network policy for the specified application type is unknown, the VLAN ID, the Layer 2 priority and the DSCP value fields will now be ignored.


DGW-5726CWMP active notifications for FXS endpoints are not sent properly when a PRI card is present.FXS, PRI

CWMP active notifications are now sent properly even if there is a mix of telephony cards.



5 Known Issues


Incident #CR #SynopsisApplies To
---DGW-7027Unable to download large VM images with some browsers.VM

It is not possible to download large VM images when using some browsers such as Internet Explorer 11.

---DGW-67954124 one-way audio problem on ports 17-24.all

One-way audio problem may happen on 4124 after many days of uptime on ports 17-24.

---DGW-6455E1T1 cards configuration is lost after backup restoration.3000 and Sentinel 400

This problem does not affect units that have never run the DGW 2.0.35 release.

For units running DGW 2.0.35, that have had the DGW 2.0.35 running, or for units that you do not know if the DGW 2.0.35 load was ever installed, use this work around:

IMPORTANT: Before you start, make sure to take a Configuration Script of your complete configuration.

  1. Acces the DGW Web page.
  2. Go to System/Hardware.
  3. For one of the ports, from the *Signaling *drop-down list, select any value. (make sure to remember the value you are changing)
  4. Click Apply.
  5. From the Signaling drop-down list, select the initial value you previously changed.
  6. Click Apply.
  7. Restart the unit.
  8. Take a backup of the configuration.

Result: This will rewrite the persistent configuration of the unit with the proper values.

---DGW-2457Downgrading to version DGW 2.0. 37.697 and below causes the DGW application to stop responding and restart.Sentinel 400

Downgrading to GA version DGW 2.0. 37 and below on a Sentinel 400, with analog cards and without a DSP card, causes the DGW application to stop responding and restart. When the DGW application restarts, the Telif service is stopped. For the unit to work properly, you will need to rollback to a DGW software version higher that 2.0.37.697.
