DGW Release Notes v2.0.40.747

The DGW 2.0 software no longer supports the Mediatrix 4104 platform.

When enabling sending SIP reason headers with Q.850 codes through the SipEp.ReasonHeaderSupport parameter, there are now a larger number of cases where the Reason headers are included in the SIP messages.

Prior to this modification, Reason Headers with Q.850 reason codes were included only when the telephony interface was an ISDN interface, and only when a reason code was provided by the ISDN interface, which excluded the presence of a reason code in case of a SIP error.

With this modification, Reason Headers with Q.850 reason codes are included:

• For all types of telephony interfaces (not just for ISDN interfaces)
• For all types of causes, including when a call is ended for a SIP cause such as incompatible media
• For all 4xx, 5xx, 6xx responses during the establishment of a call (before the call is established)
• For all BYE and CANCEL requests issued for a call.

Rulesets created prior to DGW 2.0.38 that use the actions Limit CAPS, Limit Parallel Calls, or Limit Bandwidth can now be used with the DGW 2.0.40.

IN 12567

The SipEp.GwSpecificMwiMessaging.Host parameter will now accept IpV6 addresses.

When an ACS reads a "write-only" parameter, the unit will now return "0" instead of an incoherent value.

When enabling sending SIP reason headers with Q.850 reason codes through the SipEp.ReasonHeaderSupport parameter, there are now a larger number of cases where the reason header is included in the SIP messages sent.

On the Network/Interfaces Web page, the drop list to select the Network Interface for the LLDP configuration now includes the configured IPV6 interfaces.

IN 12833

Ethernet flow control support is now advertised by ports ETH2 to ETH5 (Sentinel, G7 and S7).

The followong parameters were added:

• Device.Services.X_0090F8_IpRouting.ApplyConfig,
• Device.Services.X_0090F8_IpRouting.CancelEdits
• Device.Services.X_0090F8_IpRouting.Ipv4ForwardingEnable to the TR-069 datamodel

Trailing whitespaces (spaces and tabs) are now ignored in the following parameters:

• CRout.Route.ExpressionCriteria
• CRout.MappingExpression.Criteria RG Flags

The Cwmp service will now wait the end of a transaction before restarting needed services.

The uptime timer computation was updated. Mediatrix units no longer restart by themselves after 25 days.

A potential vulnerability was discovered in the CWMP client. This could leave us vulnerable to code injection attacks. This issue was corrected.

IN 11994

When using persistent TLS connections, repeated negotiation could occur causing the unit to unexpectedly close or significantly slow down. TLS connections are now handled properly.

In some scenarios, when many registrations were performed at startup, the Sbc service would fail to start. The Sbc service is now able to restart even if several registrations are performed at start-up.

The Event Log Web page was improved to easily log notification events per service.

• For Nlm Event notifications, the selection of notifications by a severity level group is now possible.
• The "Edit" button is greyed when Diagnostic Traces are disabled.
• To add a new row, the '+' button must be clicked.

SBC rulesets containing the Limit CAPS, Limit Parallel Calls, and Limit Bandwidth actions that were created on a DGW 2.0.38.717 version or older did not work properly on newer versions of DGW.

New parameters for these actions were introduced in DGW 2.0.38.717. Rulesets created prior to this version and which use these actions do not have these parameters and they do not work correctly when used on DGW 2.0.38 and DGW 2.0.39. Starting with version DGW 2.0.40, appropriate default values are used when the rulesets have missing parameters for these actions.

IN 12567

The Ipv6 addresses will now be accepted on the specific messaging server setting.

If an ACS tries to read a write-only parameter, the value "0" is now returned instead of an incoherent numeric value.

IN-12889

The Pots.FxoCustomBasicParameters.Impedance parameter had country impedance name without impedance values. The description was updated to help the user find the impedance value of these countries.

In the Network/Interfaces Web page, the drop list to choose the Network Interface in the LLDP configuration only contained the IPV4 interfaces. The IPV6 interfaces were not present. It was possible to select them through SNMP or CLI, though. IPv6 interfaces were added.

IN 12833

Ethernet flow control was enabled between the main processor and the first PRI card to avoid potential packet losses on the Ethernet connection between the main processor and the PRI cards.

IN 12776

When a NAPTR response is received, DNS servers are no longer blacklisted, allowing the process of SIP registration.

IN 12754

SRTP calls between Mediatrix units and MX-One were not working properly. SRTP Incoming audio can now be played.

This syslog is no longer sent when using port 0 as it is a valid substitution for the default Sip port.

It was possible to modify the IpRouting.AdvancedIpRoutes table from TR-069 but it was not possible to apply the changes because the ApplyConfig command was not supported in the TR-069 data model. Now it is available along with the Cancel/Edits command (i.e. the counterpart of the ApplyConfig command) and the Ipv4ForwardingEnable parameter (which enables/disables the AdvancedIpRoutes feature).

When editing regular expressions in the Call Router / Route Config Web page, white spaces at the end of regular expressions were not visible and were not ignored. Users could end-up with regular expressions with white spaces at the end without seeing them. Trailing white spaces (spaces and tabs) are now ignored.

The CWMP inform maximum possible value was 136 years. This was reduced to a year.

If the user changed the default password of the default username, performing a partial reset would set the password back to its default value. When a partial reset is performed on the unit, performing a restart of the unit will no longer reset the modified password to the value active before the partial reset.

The Cwmp service now checks the availability of any service before accessing them. The service is now also restarted at the end of the transaction and not after each execution that requires restarting the services.

The LLDP service no longer stops working when there are no DHCP responses and the policy changes the VLAN id several times.
