Description

IN 12439

DGW-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.

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-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-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

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.

--- DGW-239 Add Sentinel 100 support in Dgw application. Sentinel 100

The Dgw application now supports the Sentinel 100.

3 Issues Fixed

Incident # CR # Synopsis Applies To
Description
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-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-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-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-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.
