Available DGW Firmware Versions
1 Firmware Pack
The firmware pack is a binary file that contains the modules and the features to install on your Mediatrix unit when a new release is available.
2 New Functionalities
| Incident # | CR # | Synopsis | Applies To |
|---|---|---|---|
| Description | |||
| DGW-11958 | Add the outbound proxy feature for TLS and TCP in the SipProxy service. | SipProxy | |
The outbound proxy feature is now available in TLS and TCP. The SipProxy service uses persistent connections to create a path between the outbound proxy server and the local SIP proxy. The SipProxy service will now insert a Route header pointing to its configured outbound proxy as the first route if the feature is enabled. The outbound proxy server is configurable through the SipProxy.OutboundProxyHost parameter available in the DGW Web page under SIP Proxy/Configuration.

MOS estimation for the G.722 codec is now supported in the SIP PUBLISH request (RFC 6035). |
|||
IN-11411 |
DGW-11733 | Add the support of the G.722 voice codec on the Mediatrix C7, S7, G7, Sentinel 100, and Sentinel 400. | C7, G7, S7, Sentinel 100, and Sentinel 400 |
The G.722 voice codec is now available for the Mediatrix C7, S7, G7 series as well as on the Sentinel 100 and 400 platforms.

Default behavior of QSIG signaling on BRI interface New parameter Isdn.SignalingChannelInterop.InteropQsigIeInterpretation |
|||
IN-11411 |
DGW-11733 | Add the support of the G.722 voice codec on the Mediatrix C7, S7, G7, Sentinel 100, and Sentinel 400. | C7, G7, S7, Sentinel 100, and Sentinel 400 |

4 Issues Fixed
| Incident # | CR # | Synopsis | Applies To |
|---|---|---|---|
| Description | |||
| --- | DGW-12560 | The SipProxy.TlsPersistentConnectionStatus parameter was renamed SipProxy.PersistentConnectionStatus. | SipProxy |
The SipProxy.TlsPersistentConnectionStatus parameter was renamed SipProxy.PersistentConnectionStatus. The TLS Persistent Connection Status parameter under DGW/SIP Proxy/Status has changed to Persistent Connection Status.
|
|||
| DGW-12299 | SDP precondition attributes present in the SDP offer received by DGW are added to the SDP answer causing interoperability issues. | all | |
RFC 3312 SDP precondition is not supported by DGW. If SDP precondition attributes were present in an SDP offer received by DGW, these attributes were copied back into the SDP answer, which caused interoperability issues. Now, any SDP precondition attribute present in an SDP offer will be removed from the SDP answer, showing that the feature is not supported. |
|||
IN-14428 |
DGW-12033 | The QSIG signaling on BRI interface is not ECMA-143 compliant | QSIG, BRI |
The Channel Identification IE is now compliant to the ECMA-143 standard. The InteropQsigIeInterpretation interop parameter can be used to revert to the previous non-compliant behavior. |
|||
| DGW-11931 | The SSH welcome message is no longer being displayed when connecting to the CLI. | all | |
The SSH welcome message is now displayed when connecting to the CLI. |
|||
| DGW-11783 | CWMP stops responding when ACS connection requests are processed with invalid data. | all | |
The CWMP connection request processing loop was not handling invalid data correctly, and could become unresponsive. The CWMP client will now reject invalid or incomplete connection requests. |
|||
IN-14243 |
DGW-11330 | Mediatrix units may be vulnerable to CVE-2019-11479, which can cause service disruption if the vulnerability is exploited. | all |
A measure was put in place to mitigate the effects of a possible DoS (denial of service) attack as described in CVE-2019-11479. |
|||
5 Known Issues
| Incident # | CR # | Synopsis | Applies To |
|---|---|---|---|
| DGW-12306 | UDP is not yet supported by the Outbound Proxy feature. | SIP Proxy | |
UDP is not yet supported in the Outbound Proxy. The Outbound Proxy feature can be enabled if the UDP transport is disabled in the unit and if TCP or TLS is enabled. Consequently, if the Outbound Proxy is required all SIP devices located behind the SIP proxy must not use the UDP transport. |
