DGW Release Notes v2.0.42.768

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

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

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

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.

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-12889

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

IN-13099

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-13122

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

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.

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.

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

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

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

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.

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

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

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

IN-13122

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.

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

IN-13098

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

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.

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