1 Firmware Pack

The firmware pack is a ZIP binary 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 # Synopsis Applies To
Description
--- DGW-8324 Add the Image Format parameter for the creation of a virtual machine (VM) Vm

The Image Format parameter allows the user to choose a VM image format when creating a VM image. The new parameter is available in the DGW Web interface under

Under

System/

System

VM in the Virtual Machine Creation table. Possible values are:

  • raw which is the default value
  • qcow2
--- DGW-8173 New versioning schematic of DGW 2.0 application. all

The DGW 2.0 application is renamed DGW. Refer to the DGW Software Numbering Convention technical bulletin published on our documentation portal.

--- DGW-8090 Add the possibility for the Vm service to convert an existing VM image from a file format to another (QCOW2 or RAW). Vm

The "Vm.ConvertVmImage" command allows to convert an existing VM image into QCOW2 or RAW file format. The command can also compress the VM image and remove the existing image following the creation of the new converted VM image file.
--- DGW-8069 Virtual machines (VM) should be properly shut down before restarting the Mediatrix unit. Vm

When the Mediatrix unit is shut down, then a process now allows the unit to properly close the virtual machines. The new Vm.ShutdownTimeout parameter was added to configure the maximum amount of time allowed for a VM to stop. this parameter is not available in the DGW Web page.

Incident # CR # Synopsis Applies To
Description

IN-13236

DGW-8444 Unable to select the transport protocol in a Call Agent via the DGW Web page when a gateway is selected. Sbc

When a gateway is selected in a Call Agent, the configuration of the Force Transport parameter via the DGW Web page was disabled, now it is enabled.

IN-13236

 		DGW-8161 The SBC must provide additional control for the value of the Contact used in SIP dialogs. Sbc

Two new SBC Call Agent Ruleset actions were added to provide a better control of the value of the Contact used in SIP dialogs

  • Keep Contact user
  • Set Contact-URI user

IN-13390

 		DGW-8108 The warning message returned by the set command executed by the SnmpEx.Access.Command is interpreted as an error. Snmp

The SnmpEx.Access.Command (1.3.6.1.4.1.4935.1000.100.200.100.900.1.100.1.100.200.0) was interpreting the warning message returned by an executed set command as an error. The warning message is now interpreted as a success and not an error, as it should.

IN-13236

 		DGW-7942 The Sbc service is removing parameters of the SIP Contact header, causing interoperability issues. Sbc

The Sbc service was removing the parameters of the SIP Contact header.To allow greater control over SIP Contact parameters, new Sbc Call Agent Ruleset actions were added.The following new Call Agent Ruleset actions were added to control which Contact header parameters are relayed:

5 Known Issues

Incident # CR # Synopsis Applies To
---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.

  • Acces the DGW Web page.
  • Go to System/Hardware.
  • For one of the ports, from the *Signaling *drop-down list, select any value. (make sure to remember the value you are changing)
  • Click Apply.
  • From the Signaling drop-down list, select the initial value you previously changed.
  • Click Apply.
    • Restart the unit.
  • 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.
