DGW Release Notes v44.2.1669

A new Pause command can now be used in scripts to insert waiting time. The command is "Pause XX" where XX is a value in seconds (maximum 300).

The online help text displayed for an element on the DGW Web pages now includes the name of the parameter(s) related to the element.

For example the Online help of the Register field, located in the SIP/Registrations/Endpoint Registration table was:

will now be:

IN-13461

The default value of the Conf.ScriptsDhcpOptionsFormat parameter is now AutoDetect. For customers with non-default value in their profile, their default value stays the same.

IN-13855

The range of the SipEp.DefaultSessionTimerMinimumExpirationDelay and SipEp.DefaultSessionTimerMaximumExpirationDelay parameters is now 180..86400.

The Ems service now supports periodic provisioning using Virtuo.

The provisioning frequency can be configured for hourly, daily, or weekly provisioning, at a configurable date/time range.

Refer to the Reference Guide for more information on the following new parameters:

• Ems.PeriodicProvisioningTimer
• Ems.HourlyTimeRange
• Ems.DailyTimeRange
• Ems.WeeklyTimeRange

These new parameters are not available in the DGW Web interface.

For both Trunk and Endpoint gateways, a new Keep-Alive method is now supported. If the SIP gateway is configured for the TCP or TLS protocol, the TcpKeepAlive method can now be activated through the SipEp.SipKeepAliveMethod parameter. The new SipEp.SipKeepAliveRetry parameter was also added under SIP/Servers

The SipEp.DefaultSipFailoverConditions and SipEp..GwSpecificFailover.SipFailoverConditions parameters had their syntax extended to support additional failover conditions for endpoint gateways:

• 504OnInvite: Failover occurs when a 504 response is received to an INVITE. No condition on the content of the response.
• 5xxOnInvite: : Failover occurs when a 5xx response is received to an INVITE. No condition on the content of the response.

The Cli.SshSecurityLevel parameter was added to allow the selection of three levels of security of the SSH connection for the CLI.

By default the SSH connection for the CLI uses a Standard security level, which is a good compromise between security and interoperability with SSH clients. The new SSH Security Level parameter is available under DGW Web interface/Management/Misc.

In DGW 44.2, the embedded SSH server for the Cli service has been upgraded to replace some unsecure ciphers by new secure ciphers.

Moreover, the support of DSA host keys has been removed, in favor of ECDSA host keys. The RSA host keys are still supported.

The SipEp.SipKeepAliveMethod parameter was updated: the new TCP Keep- Alive value was added.

The new SipEp.SipKeepAliveRetry parameter was added under SIP/Servers

IN-13461

The default value of the Conf.ScriptsDhcpOptionsFormat parameter is now AutoDetect. For customers with non-default value in their profile, their default value stays the same.

IN-13855

The range of the SipEp.DefaultSessionTimerMinimumExpirationDelay and SipEp.DefaultSessionTimerMaximumExpirationDelay parameters is now 180..86400.

IN-13865

• Improved the Ethernet driver on S400
• Increased the network priority on S400

A new SSH Security Level parameter is available under DGW Web interface/Management/Misc.

Some old SSH clients software may no longer be able to connect to the Cli service due to a default configuration that is more secure than previously. If that is the case, there are two options:

• Media5 recommends using a recent SSH client software.
• Or the Cli.SshSecurityLevel parameter can be configured to Permissive from the Management/Misc DGW Web page.

Some old SSH clients software may no longer be able to connect to the Cli service due to the removal of the DSA/DSS keys. Media5 recommends using a recent SSH software to connect to Mediatrix units.

On the first SSH connection following the upgrade to DGW 44.2, the SSH client software will likely ask again to trust the Mediatrix unit. This can be prevented by configuring the SSH client software to prioritise a RSA host key algorithm before the ECDSA algorithm.

The ISDN, R2, and Eam DGW Web pages are now available with the custom profile.

IN-13430

When the unit was started, the execution of the configuration script could fail if provisioning from an ACS was executed during the same interval of time. This happened when both systems were using the same user and competing for setting the configuration of the unit. When the unit is started, if a script is executed, all Set operations via TR-069 are now blocked until the script is completed in order to avoid having two methods configuring the unit at the same time.

On the Configuration Scripts web page, the "#" no longer appears and the page can be refreshed.

IN-13865

Sometimes, when a network packet burst occurs, the Mediatrix S400 drops some packets internally instead of sending them to the network interface. RTP packets are now all sent to the network interface.
