1 Firmware Pack

The firmware pack is a ZIP 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.

Description
IN 12439	DGW-

3572Add new packet capture options for remote troubleshooting.all

Packet capture functionality was added in the NLM service, allowing captured packets to be sent to a file in the File service or transferred in real time via a PUT to a HTTP server. This packet capture can be used from all configuration interfaces with the exception of TR-069.

The packet capture uses the new following parameters and commands:

Nlm.PCaptureState
Nlm.PCaptureNbFrames
Nlm.PCaptureNbSecs
Nlm.PCaptureFilter
Nlm.PCaptureFileUrl
Nlm.PCaptureLinkName
Nlm.PCaptureStart
Nlm.PCaptureStop
Nlm.PCaptureTransferCertificateValidation
Nlm.PCaptureTransferCertificateTrustLevel
Nlm.PCaptureTransferCipherSuite
Nlm.PCaptureTransferTlsVersion

The packet capture can be configured via the Web interface, under the System/Packet Capture tab.

4916	The session-id is not regenerated upon Web login.	Web Service
The session-id present in the cookie is now regenerated systematically upon login. The session-id is also cleared in the cookie on logout.
IN 12045	DGW-3570	SDP offers can now include the ptime attribute.	all
The ptime attribute in SDP offers can now be added. Two new parameters were added to the Web interface: Include ptime Attribute : Specifies what value must be put in the ptime attribute of the SDP offers. Configured ptime Attribute : Specifies the configurable value to be put in the ptime attribute of the SDP offers provided the Include ptime attribute parameter is set to Declarative, Configured . The Include ptime Attribute parameter can have 3 values: Disabled Declarative, Preferred Codec : Takes the ptime that the preferred codec would use. Declarative, Configured : Takes the value of the Configured ptime Attribute parameter.
IN 11925	DGW-2462	Support the G.723.1 codec on Mediatrix C7, Mediatrix G7, and Sentinel units.	Sentinel, G7, and C7
The G.723.1 codec is now supported on the Sentinel, the Mediatrix C7, and the Mediatrix G7 units.
---	DGW-

3472Allows loading a MOH music file from the local file system.allIt is now possible to transfer a mp3 file for MOH using the file service. The mp3 file must be imported on the unit via the file service, with the "Path" or "Destination" set to "moh/". Then, in the "Music on Hold" configuration page, "file://filename.mp3" will be accepted has a valid URL.

1184	Calls are rejected even if some DSP resources are still available.	Sentinel
Each endpoint is statically bounded to a specific DSP on the unit. This may lead to call rejections even if some DSP resources are still available because of an unbalanced resource utilisation. Endpoints requesting DSP resources to process a call are now dynamically bounded to the DSP with the most available resources on the unit. At the end of the call, DSP resources are freed and are available to be used by other endpoints. This ensures a balanced resource utilisation and leads to more successful calls processed by the unit.
---	DGW-239	Add Sentinel 100 support in Dgw application.	Sentinel 100
Dgw application now supports the Mediatrix Sentinel 100.
---	DGW-235	The graceful restart is now supported by the Sbc service.	Sbc service
When a graceful restart is executed (either because a service is restarted or because of an automatic restart during a firmware installation) the Sbc service will refuse during the grace delay any new calls and will wait for all active calls to end before restarting the unit. If the grace delay expires, all active calls will be ended before restarting the unit.

2 Modified Features, Functionalities, and Interface Modifications

Incident #	CR #	Synopsis	Applies To
Description
	DGW-

3981Syntax of the Nlm.SyslogRemoteHost parameter not validated.Nlm

The syntax of Nlm.SyslogRemoteHost is now validated when a new value is set via Web page, the Cli, Snmp, or a configuration script. The upgrade and restore functionalities are not affected by this validation.

5491	Calls incoming from SIP to ISDN fail on G7 when the Local Firewall Default Policy is Drop.	Lfw
All internal connections will be accepted when the Lfw Default Policy is Drop.
	DGW-4918	The organisation of the parameters in the Firmware Upgrade Web page can be confusing.	all
Go to Management\Firmware Upgrade. The following parameters were moved to a separate table at the bottom of the page: Automatic Restart Enable Default Settings On Restart Automatic Restart Grace Delay Image Added
IN 12439	DGW-4916	The session-id is not regenerated upon Web login.	Web Service
The session-id is now regenerated upon login to prevent session fixation attacks.
	DGW-4897	SBC Rulesets with CAPS action consider calls with re-INVITE as separate calls.	Sbc
The CAPS action in SBC ruleset now treats two INVITEs with the same alias as the same call attempt within 30 seconds. This ensures that re-INVITE won't be blocked.
---	DGW-3791	On the Mediatrix 3000, the Sbc_Configuration.cfg script configures non-optimal gateway names in the SipEp.UserAgents table.	3000
The Sbc_Configuration.cfg script is used to configure a Mediatrix 3000 unit to run as an SBC. This script produced non-optimal values for the SipEp.UserAgents[].GatewayName parameters for FXO, BRI, and E1/T1 ports. The gateway name was set to "All". This was changed to "trunk_lines_gw" to be more consistent with these types of ports.
IN 12045	DGW-3570	SDP offers can now include the ptime attribute.	all
The ptime attribute in SDP offers can now be added under the SIP/Interop tabs of the Dgw Web interface. Image Added

Description
	DGW-

6311Received Reinvites with the same CSeq used in the invite causes one way audio or call failures.Sbc

If the Sbc receives a reinvite using the same CSeq as the one of the invite it sent, it no longer causes one way audio or call failures.

DGW-6238PCM captures are sent to UDP port numbers 5000+X and 6000+X, where X is the channel numberall

The PCM captures were sent to UDP port numbers 5000+X and 6000+X, where X was the channel number. Now they are always sent to ports 5001 and 6001.

DGW-6197Ciphers are not listed by Sbc in the proper order.all

The order of the ciphers was no longer from most secure to less. This was corrected.

DGW-6196Cipher AES_256_CM_HMAC_SHA1_80 is ignored by the SBC.SBC

When offered a AES_256_CM_HMAC_SHA1_80 in SRTP, the SBC no longer ignores it.

IN-12876

DGW-6135Link to Date/Time Criteria Editor not working.all

The link to the "Date/Time Criteria Editor" page available in the Transformation Rule editor Web page has been restored.

DGW-5391Mediatrix 3XXX series units sometimes close unexpectedly after an update.all

Mediatrix 3XXX Series units no longer close unexpectedly after an update.

DGW-5073Configuration script not working properly for subnet settings.Dhcp

The subnet settings in the DHCP configuration were incorrectly exported using the configuration script.

DGW-5033The %capubip% macro used in a Registration Agent contact creates a Contact containing a port specified as ":0"SBC

When the Sbc.RegistrationAgent.Contact parameter was configured with the %capubip% macro while the corresponding port was set to 0 in the Sbc.SignalingInterface table, the REGISTER request was sent with a Contact containing a port specified as ":0" . In this case, the Contact is now created without a port .

DGW-3981Syntax of the Nlm.SyslogRemoteHost parameter not validated.Nlm

The syntax of the Nlm.SyslogRemoteHost parameter is now validated when a new value is set via the Web page, the Cli, Snmp, or a configuration script. The upgrade and restore functionalities are not affected by this validation.

5 Known Issues

Incident #CR #SynopsisApplies To---DGW-6418allDescription is empty in issue RN (DGW-6418)---DGW-6358allDescription is empty in issue RN (DGW-6358)DGW-

5491	Calls incoming from SIP to ISDN fail on G7 when the Local Firewall Default Policy is Drop.	Lfw
The Local Firewall drops all internal connections, so we add a default rule to accept these connections.
IN 12478	DGW-5425	When the unit is restarted, the Telif service switches to manual.	all
When the unit is restarted, the Telif service no longer changes from automatic to manual because of a timing issue.
IN 12606	DGW-5380	Unit may become unreachable when many clear channel calls are performed.	all
The unit is no longer unreachable when a clear channel call fails to allocate the DSP channel on a 3000 Series unit.
	DGW-5361	Deactivating the traces of the Conf Script Modifiers also inadvertently deactivates the traces of the Call Manager.	all
Disabling the Conf Script Modifiers diagnostic traces no longer disables the Call Manager traces.
	DGW-5105	The HTTP User Agent field is not set when a firmware upgrade - multiple file update - is triggered via CWMP.	all
The HTTP User Agent field is now set when a firmware upgrade - multiple file update - is triggered via CWMP.
	DGW-4918	The organisation of the parameters in the Firmware Upgrade Web page can be confusing.	all
With the addition of single file update it was hard to get which parameter was needed for which transfer type. The page was re-ordered and re-divided so it is now easier to understand.
	DGW-4897	SBC Rulesets with CAPS action consider calls with re-INVITE as separate calls.	Sbc
A call could be blocked after a re-INVITE because the call attempts per time unit (also known as CAPS) action in the SBC Ruleset was considering each INVITE as a separate calls, which is no longer the case.
	DGW-4895	RTCP XR packets are not relayed by the SBC therefore no calling statistics are generated.	Sbc
The SBC was stopping RTCP XR packets and considering them as malformed packets. This was corrected and now the SBC properly relays the packets to the intended target. The SBC does not support RTCP XR, so it cannot make use of the packet itself.
IN 12517	DGW-4707	The Mediatrix 4404 could not handle 6 simultaneous calls when SRTP was enabled with compression codecs.	4404
This limitation was removed. The 4404 can now use all 8 channels, regardless of the configuration.
	DGW-4473	The Mediatrix Sentinel 400 may restart when targeted by a specific SQL injection attack in SIP.	Sentinel 400
An issue in the logging subsystem has been identified and corrected.The SBC logging subsystem no longer triggers the Sentinel to be restarted.

---DGW-2457Downgrading to version DGW 2.0. 37.697 and below causes the DGW application to stop responding and restart.Sentinel 400Downgrading 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


	DGW-4264	In an SBC specific scenario using the "Force SRTP" ruleset, the voice path is cut after a few seconds.	Sbc
The SBC was replacing the SDP crypto attribute in every 180, 183, and 200 responses, which was not supported by the unit receiving these responses. The SBC now reuses the same crypto attribute in these responses.
IN 12297	DGW-4140	When used as a property criteria in a Call Router route, the "Calling Host" call property is missing the port.	Call router
The port information was missing from the "Calling Host" call property for calls coming from SIP. Now, when the Contact in the SIP INVITE has a port, the port is appended to the Calling Host Call Property.
IN 12314	DGW-4120	Re-INVITEs are refused by the SBC because the peers use the alias from the prior SIP challenge.	Sbc
The SBC now handles Re-INVITEs with the alias received prior to the SIP challenge.
---	DGW-3806	Occasional poor audio quality when making a call.	Sentinel
The RTP packets were not sent at a steady state rate on the Sentinel 400, causing poor audio quality if the jitter buffer of the other device was not of good quality. This has been solved.
---	DGW-3791	On the Mediatrix 3000, the Sbc_Configuration.cfg script configures non-optimal gateway names in the SipEp.UserAgents table.	3000
The Sbc_Configuration.cfg script is used to configure a Mediatrix 3000 unit to run as an SBC. This script produced non-optimal values for the SipEp.UserAgents[].GatewayName parameters for FXO, BRI, and E1/T1 ports. The gateway name was set to "All". This was changed to "trunk_lines_gw" to be more consistent with these types of ports.
---	DGW-

2046The LLDP service stops working.allThe LLDP service no longer stops working when there are no DHCP responses and the policy changes the VLAN id several times

3541	Calls are sometimes dropped when an INVITE containing no Session Description Protocol (SDP) is issued.	Sentinel
The calls are no longer dropped when the Mediatrix SBC routes an INVITE without SDP and receives a 183 provisional response with SDP followed by a 180 with the same SDP, or a 180 Ringing response with SDP followed by a 200 OK with the same SDP.
---	DGW-

1244The 1024k file limit capacity is not detected on units that support the Log To File.allIf more space than permitted is used, unwanted behaviours such as scripts not being properly executed or problems upgrading or downgrading DGW

3364	When pressing a series of touch keys, the tone sometimes remains locked for a few seconds to one of the touch keys.	all
When using any codec with DTMF out of band and rtp, pressing several touch keys in a row could cause one of the DTMF tones to remain locked on a touch key tone causing call issues. This has been fixed and is no longer the case.
---	DGW-

1228Unable to install the Windows Server 2008 and 2003 from USB external device.VM service

It is not possible to use a USB external device to install the Windows Server image (2003 and 2008) OS when creating a virtual machine.

Anchor

3117	The SBC answers authentification challenges without any username/password information.	Sbc
For the SBC to answer to authentification challenges correctly, a rulesets needs to be used. An issue was found that when the SBC received the challenge he would answer without any information on the username and password to use. This was is conflict with the rulesets and cause the connection to fail.
