v. 2.0.41.762


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.


2 New Functionalities


Incident #CR #SynopsisApplies To
Description
---DGW-6378Introduction of the new Survivability Proxy (SipProxy) service.SipProxy

In case of Hosted SIP Services failure, the new Survivability Proxy service (SipProxy) ensures internal call control for registered IP phones and other connected equipments while redirecting external calls to the PSTN, if available.

This service is available on the C7, G7, S7, Sentinel 100, and Sentinel 400 platforms. A field-installable licence is required to activate this service.

---DGW-6356Add the support of RFC4730 Event Package for Key Press Stimulus (KPML).all

The support of RFC4730 Event Package for Key Press Stimulus (KPML) when acting as a user agent server was added. The feature is disabled by default and can be activated via the SipEp.UasKpmlSupport parameter.

---DGW-6175Increase the jitter buffer from 135 ms to 900 ms.Sentinel 400, Sentinel 100, C7, S7, and G7

More space was reserved for the jitter buffer allowing the Sentinel 400, the Sentinel 100, the Mediatrix C7, the Mediatrix S7, and the Mediatrix G7 to support a jitter buffer value up to 900 ms. A new mode of packet processing optimised for large Jitter buffer sizes was also added.

---DGW-5996Add the Argentina country tones.all

Argentina country tones are now available.



3 Modified Features, Functionalities and Interface Modifications


Incident #CR #SynopsisApplies To
Description
---DGW-6175Increase the jitter buffer from 135 ms to 900 ms.Sentinel 400, Sentinel 100, C7, S7, and G7
  • Sentinel 400, Sentinel 100, C7, S7, and G7 platforms now support maximum jitter buffer values up to 900 ms.
  • It is now possible to set the nominal jitter buffer value for custom voice and voice band jitter buffer configurations.
  • Using a value of 0 for the nominal jitter value is interpreted as the middlepoint between the minimal and maximal jitter buffer values.
  • The Mipt.InteropPacketReceptionMode parameter was added, for which the default value is Mode1. With this option, processing of unsupported inbound packetisation times was removed to increase quality (ex: 10-100 ms with increments of 1 ms for the G711). Legacy mode is still present as Mode0, but is not enabled by default.

DGW-5946SDP offers with image and RTP ports fail.SipEp

Add new value for the parameter SipEP.InteropAllowAudioAndImageNegotiation to allow the customers to disable image port in answer. The SipEP.InteropAllowAudioAndImageNegotiation parameter now supports the following new enum values to allow the customers to disable image port in an answer.

  • DisableOffer: Outgoing offers never include image and audio simultaneously. Incoming offers with audio and image media with a non-zero port are answered with audio and image media, but considered as offering only audio.
  • DisableAll: Outgoing offers never include image and audio simultaneously. Incoming offers with audio and image media with a non-zero port are answered with audio and image media but the image media will be disabled. If it has the T.38 codec enabled and wishes to send or receive fax, a new re-INVITE will be sent to negotiate image port. RG Flags

IN-12721

DGW-6670Early Media RTP sent from the Mediatrix unit are blocked by remote peer network restrictions.all

New SipEp.InteropActivateEarlyMediaOnProvisionalResponseAck interop parameter:

  • Disabled: During the SIP call establishment, the first RTP packet is triggered by the transmission of the "SIP 183 Progress" (Default behavior)
  • Enabled and all conditions are encountered: During the SIP call establishment, the first RTP packet is triggered by the transmission of the "200 OK" of the PRACK of the "SIP 183 Progress".
---DGW-6582Error messages are not displayed on the Packet capture Web page.all

A new message "There is no packet capture in progress." has been added.

4 Issues Fixed


Incident #CR #SynopsisApplies To
Description

IN-13222

DGW-7652Out of order RTP Events may in some cases have wrong sequence numbers.all

Out of order RTP Events now have the correct sequence numbers.

IN-13057

DGW-6936The Contact header contains a wrong URI in the 200 OK for an INVITE-Replaces.SipEp

In a 200 OK for INVITE-Replaces that transfers an outgoing call; the Contact header contained the URI of the first transferor. This Contact header will now contain the Caller URI.

IN-13057

DGW-6899The Referred-by header copied from the REFER to the INVITE is incomplete.SipEp

The Referred-by header copied from the REFER to the INVITE contained only the URI and did not contain the parameters. Now all parameters are copied with the URI in the Referred-by header.

---DGW-6789When the firmware is upgraded from DGW 2.0.29 or older to DGW 2.0.39 or DGW 2.0.40, the Option 66 and Option 67 provisioning configuration in the Dhcp service is lost.all

Option 66 and Option 67 provisioning configuration table is no longer lost when the firmware is upgraded to DGW 2.0.41.

Upgrading to loads DGW 2.0.39 and 2.0.40 will not be fixed.

---DGW-6776The Sbc service registration cache would sometimes get wrong expiration values.Sbc service

When multiple registrations were received at the same time, the expiration value could get corrupted and show a value in the past. The Sbc unit can now properly handle multiple registrations at the same time.

---DGW-6771During DTMF conversion, the *(star) and #(pound) keys are sent as 0.SBC unit

When converting INFO towards AVT on the SBC unit, the *(star) and #(pound) keys are no longer sent as 0.

IN-12721

DGW-6724Outbound rules are not executed for REGISTER or OPTIONS.SBC

In the Sbc service, outbound rules were only applied to certain Sip traffic. Both inbound and outbound rules are now applied to all Sip traffic.

---DGW-6693When a wrong certificate is used, the SBC unit can become unresponsive forcing the user to restart the unit.Sbc service

When the Sbc service was using a wrong certificate to validate a connection with a registrar, the unit would sometimes get unresponsive forcing the user to restart the unit. When the Sbc service uses a wrong certificate, the connection fails, but the unit no longer needs to be restarted.

IN-12721

DGW-6670Early Media RTP sent from the Mediatrix unit are blocked by remote peer network restrictions.all

The new SipEp.InteropActivateEarlyMediaOnProvisionalResponseAck parameter was added to delay the transmission of the first early-media RTP packet therefore it is no longer blocked by the remote peer network restriction. The interop parameter can have the following values:

  • Disabled: During the SIP call establishment, the first RTP packet is triggered by the transmission of the "SIP 183 Progress" (Default behaviour)
  • Enabled and all conditions are encountered: During the SIP call establishment, the first RTP packet is triggered by the transmission of the "200 OK" of the PRACK for the "SIP 183 Progress".

IN-12567

DGW-6648Missing telephony interfaces in the "IfTable" MIB-2 table.all

VLAN interfaces were being added to the IfTable, overlapping some existing telephony interfaces. Some telephony interfaces were therefore no longer displayed in the IfTable, even if they existed. There is no longer any overlap between the different sources of interfaces in the IfTable.

---DGW-6582Error messages are not displayed on the Packet capture Web page.all

The packet capture error messages are now displayed on the Web page.

IN-12842

DGW-6565Slow and unsafe TLS version negotiation for persistent connections.all

When a TLS persistent connection was created, it would only use the highest supported TLS version for the handshake. If the handshake was refused for version reasons, the connection was closed then re-opened with a lower version. The process would repeat until a version supported by both sides was found. The problem was that this method was both slow and unsafe.

With the new behaviour, the new connection will contain all the supported TLS versions and will negotiate which version to use in the first handshake.  This new negotiation behaviour is faster and safe.

---DGW-6357Notification message has changed.all

The destination URL is no longer displayed in the "1000-Packet capture started" notification.

IN-12549

DGW-5946SDP offers with image and RTP ports fail.SipEp

When the parameter SipEP.InteropAllowAudioAndImageNegotiation is set to Disable and the unit receives an offer with image and audio, it responds with an actual port on image m=line but the image is disabled and the fax reception fails.  The SipEP.InteropAllowAudioAndImageNegotiation parameter will now support new enum values (DisableOffer and DisableAll) to allow customers to disable image port in an answer.

IN-12567

DGW-5895Incoming packet loss on the network causes bad voice quality.all

The voice quality is now better when there is incoming packet loss on the network.



5 Known Issues


Incident #CR #SynopsisApplies To
---DGW-7031A Virtual Machine can use more storage than capacity configured in Vm service.Vm

A Virtual machine can be created with a disk capacity higher than the disk capacity configured in VM configuration file.

---DGW-7027Unable to download large VM images with some browsers.VM

It is not possible to download large VM images when using some browsers such as Internet Explorer 11.

---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.

  1. Acces the DGW Web page.
  2. Go to System/Hardware.
  3. For one of the ports, from the *Signaling *drop-down list, select any value. (make sure to remember the value you are changing)
  4. Click Apply.
  5. From the Signaling drop-down list, select the initial value you previously changed.
  6. Click Apply.
  7. Restart the unit.
  8. 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.

DGW-1244The 1024k file limit capacity is not detected on units that support the Log To File feature.all

If more space than permitted is used, unwanted behaviours such as scripts not being properly executed or problems upgrading or downgrading DGW.
