This Fix Update provides DB2 V11.1 support for BVR V6.1 for AIX. For details of this feature, please refer to the following Solutions article:
48000984791-blueworx-voice-response-v6-1-for-aix-support-for-db2-v11-1

Also the following issue has been fixed:

Important: After installing this PTF, you will need a license key from your Blueworx sales representative or Blueworx support for BVR to continue taking calls. There is a grace period of 45 days in which to do this. Please see below for further details.

New feature contained in Fix Level 6.1.0.523:

In order for customers to ensure their compliance with license terms, Blueworx Voice Response has now been updated with a different License Use Management (LUM) system, a more modern approach to managing active channels.

The system will now require a software key to ensure that a Blueworx Voice Response system uses only licensed channels. The key is unique to each specific system and must be generated by a Blueworx support representative. This new level of management provides customers and Blueworx with coverage to ensure that all licenses have been purchased and that customer systems remain in compliance.

After installing BVR 7 for AIX 7.0.0.2, BVR for AIX 6.1.0.523 or BVR for Linux 7.2.2, you will need to follow the step-by-step instructions at:

48000984740-bvr-license-key-procedure

and contact our support team who will generate a unique software key for your system. A software key looks similar to this:

XE8RGT-LGFVK3-JDKY5B-7WCJN6-WRUXGP

Licenses can be used on any system; however, a License Key can only be used on the system they were generated for. If you wish to move your licenses to a different system you will need to contact Blueworx Support and provide the System Identifier of the new system and a new License KEY will be generated for that system.

New fixes contained in Fix Level 6.1.0.523:

Internal Defect fix

• Update to GSKit 8.0.14.53 CC certified stream version

Internal Defect fix

• A new configuration option "Late Offer on Outbound Calls" has been added within the "Voip SIP Signalling" configuration panel. If set to yes then no SDP will be provided on the outgoing INVITE request associated with an outgoing call. If set to no (the default) then behaviour will be unchanged for outgoing calls and SDP will be attached to outgoing INVITE requests
  
  For further information on this feature, please refer to the following article:
  48000984795-support-for-late-offer-on-voip-sip-outbound-calls

Internal Defect fixes

• Fixed the following error that can occur when running dtProblem:

  get_db2info[25]: DB2PRODDIR: 0403-040 Parameter null or not set.

• Fixed a problem that was resetting the ownership and permissions on file /etc/rc.dirTalk everytime the user ran vae.setuser. This file should be owned by root so this fix allows you to do this without having to go back again to reset it again.
• Fixed some problems associated with the use of MST (MRCP state tables) and MRCP custom server. Within an SSI setup, ownership of the MRCP custom server cannot be achieved by running certain commands such as dtjenable and vae.setuser on the SSI client. This fix provides detection of this and details on how to run these commands on the SSI server. This fix also removes a dependency for the Speech Client fileset to be installed before the ownership of the MRCP custom server could be updated by vae.setuser.

Internal Defect fix

• The wvrtrunk command does not complete and hangs when attempting to enable trunks (using command "wvrtrunk -e -t all" for example) if there are any adapters containing trunks that are set as "defined".
  This will be corrected by ensuring any trunks that are set to "defined" are ignored when attempting to enable or disable trunks, as expected.

Internal Defect fix

• DTTA adapter dump files are incorrectly created with a length of 0 bytes. This has no customer implications; however the dump files are used as part of the support process.

Internal Defect fix

• Improvement to dnd statistics monitoring - active chans now gives more accurate results.

Internal Defect fixes

• Previously running vae.setuser did not modify the owner for files in $DTJ_LOGS (/var/dirTalk/DTBE/dtj_logs). The owner of files in $DTJ_LOGS (/var/dirTalk/DTBE/dtj_logs) is now set to the owner specified on the vae.setuser command.
• Fixed very bad DTNA compressed voice quality. This affects the recording of compressed voice rather than playing compressed voice segments.
• GSKit 8.0.14.32 CC certified stream version security update
• dtProblem now validates certificates in keyring.db and saves in security.txt inside dtProblem zip

Internal Defect fix

• Removed an incorrect VOIP SIP overload warning. This warning incorrectly reports that WVR has become overloaded. VOIP SIP incorrectly assumes a single threaded DTNA and also uses invalid DTNA statistics. The warning has been removed as the DTNA has specific warnings on a per thread basis which are much more accurate.
  
  The reported warnings are DTNA/SIP System Overload Warnings with an errno of 29805 with the message "Some incoming calls are not being answered to prevent the system from being overloaded."

Internal Defect fix

• This PTF contains changes to the help text associated with the VOIP proxy mode parameter. These changes clarify the support and operation of the Automatic Service Lookup:DNSSRV method.

Internal Defect fix

• Fix a problem with CHP and playing segment, audio name and greeting files. If the audio files are stored in a compression format opposite to the system compression format the audio files will be ignored by WVR. With the fix any play and check storage will check both the system compression and then the opposite compression format.

Internal Defect fixes

• Fixed 3 problems in the SIP REGISTER mechanism:
  1. Fixed the CSEQ to increase by 1 for each new message rather than incorrectly remain at 1.
  2. Corrected the code to recognise an expiration length if received within the contact header rather than in an expires header.
  3. Added a RegisterAs option for those registrars that do not deal with hostnames, only IP addresses. By default, WVR will use its hostname contact address. RegisterAs is used to specify an IP address or hostname to override the default value on a per-host basis in the master.ini file. See the description in $SYS_DIR/voip/master.ini.orig for more details.
• Fixed internal system monitor functionality.

Internal Defect fixes

• Fixed to ensure that all attributes required by a Nuance server are included in a TTS <speak> request
• Fixed the processing of a 404 MRCP return code returned in a MRCP COMPLETE status message in response to a Speak request sent to a speech server.
• Fixed the calculation of a MRCP header field sent when issuing a speak command to the MRCP speech server.
• Fixed processing of MRCP header fields to allow processing of session ID returned by Loquendo.
• Fixed processing of session attributes returned from speech server so that MST can process unsupported attributes without returning an error. .
• Added an output log to MST_Import to ensure problems can be debugged.
• Added a new DTMF algorithm variant 2 that will only report DTMFs that are on for at least 60ms (Note, this is a Field access level system parameter). This should only be used if double detections are occuring for DTMFs and the audio stream contains a smaller clipped DTMF before the real DTMF. This can occur when TDM voice is converted to VoIP and then back to TDM before entering the DTXA/DTTA. The gateway doing the TDM to VoIP conversion can ended up leaving a little bit of the original tone before declaring an RFC2833 DTMF. When the stream is converted back into TDM the RFC2833 generates a new tone sometime after the original tone. Thus two DTMFs appear in the audio stream.

Internal Defect fix

• Fixed a problem to ensure that the VXML2 termchar shadow variable is set after a <record> is terminated by a DTMF key.

Internal Defect fixes

• Usability updates to the DTcheck_bin utility.
• Report back correct error code when attempting to log into the same mailbox simultaneously.
• Fix auto restart scripts for the DTNA adapter.
• Fixed incorrect message length reported when pausing the message during recording. The length used to just contain the last segment of the message rather than all segments.
• Fixed a potential problem with vae.setuser when changing the default WVR user from dtuser to another AIX user id. Before the fix, there was a chance that any new executables shipped as a result of fixes etc would not have their file ownership changed to the new user.
• Fixed a problem with restarting WVR devices if WVR was still running when the machine was rebooted. If the dtline devices end up in the defined state then WVR doesn't recover the devices correctly. This results in script errors appearing in DTstatus.out and trunks failing to appear in WVR.
• Fixed a machine crash due to a race condition where the DTNA sends trunk information to the WVR device driver during a shutdown. The WVR device driver attempts to access the trunk information from the DTNA via an internal structure which has since been freed.
• Outbound RFC2833 packets fixed to use the correct payload type.
• Added better filename reporting to vm_integrity and DTverifydb

Internal Defect fixes

• Fixed the support of CDR recording of VXML applications.
• Fix a codec problem with the library path sometimes not being initialised correctly. When this occurs audio files will not be played.
• Fixed an internal WVR V6.1 build issue.
• Correct release level checked by DB2_CHECK script and DT6_DB2_SPEC

SS7_D7 Fixes

SpeechClient Fixes

Internal Defect fix

• Moved some excess MRCP tracing to trace level 9. This reduces the extra unwanted trace at level 2 that was masking some other customer problems.

Internal Defect fixes

• Fixed internal error that was caused when MRCP servers do not respond within timeout window. This error would cause an OutOfMemory Exception in the VRBE error logs.
• Fixed internal system monitor functionality.

Internal Defect fix

• Fixed interpretation of grammarID that could cause speech recognition results to be ignored for some speech vendors.

Internal Defect fixes

• Fixed an issue where the following error would appear under heavy call load:
  Unhandled exception occurred during MRCP message receive. Details: java.lang.NullPointerException at com.ibm.telephony.directtalk.mrcp.ReceiverThread.run (ReceiverThread.java:197)
• Ensure logging of Speech Resource related connection problems at startup.
• Fixed an issue with MRCP not honouring the negotiated RTSP port on SETUP messages, which would instead stream to the default port.

Internal Defect fix

• Removed a spurious check in the MRCP plugin that generated the following error if a speech server other than WVS was used.
  
  (1007560) WVR can only be used with Blueworx Voice Server.
  
  There is no limitation on the MRCP speech servers that can be used with WVR 6.1.

VRBE_XML Fixes

Internal Defect fix

• Fixed an problem where WVR would not properly process 4XX and 5XX HTTP return codes responding to fetches, taking the empty response as the document. The error code should now be correctly logged rather than just resulting in a parse error such as "VXML browser terminated with exception com.ibm.vxi.intp.BrowserProcException: VXIContext::interpret"

Internal Defect fixes

• Fixed Single Call Mode CCXML to prevent a bug where applications would take 30 seconds to answer calls, playing silence instead of progressing with the call.
• Fixed an issue where an incorrect error message would be shown if rejecting an inbound call due to the default application being unavailable, instead the message would read "Unknown called

dtj.plexmanager.logging=false

Internal Defect fix

• Fixed a problem that caused a VXML consult transfer to fail with a timeout when using Genesys CTI

Internal Defect fixes

• Previously the Genesys Framework configuration panel provided by dtjit had "Client Name" and "Call ID Range" as optional parameters. This was incorrect and these parameters have now been modified to be mandatory. At the same time typical default values have been provided for the Start and End settings for "Call ID Range".
• Provide new AAIKVPSeparator parameter within default.cff TelephonyService to override default AAI separator character.
• Improve error reporting when attempting to parse an invalid VXML document. The trace and log will contain URI (including attributes), line number, column number and XML parsing error. The logging showing the semi parsed VXML document as been removed as this was confusing and unhelpful.
• Fixed a rare NullPointerException. The NullPointerException was reported as:
  (DTJ1008046) FAILURE: VXML2TurnCoordImpl.doField Caught a
  RuntimeException: java.lang.NullPointerException
  at com.ibm.wvr.vxml2.VXML2TurnCoordImpl.doField
  (VXML2TurnCoordImpl.java:1359)
  at com.ibm.wvr.vxml2.VXML2TurnCoordImpl.doTurn
  (VXML2TurnCoordImpl.java:269)
  at sun.reflect.GeneratedMethodAccessor32.invoke
  (Unknown Source)
• Fixed internal system monitor functionality.
• Fixed specification non-compliance where we would ignore the Path set on any cookie headers that we received in VoiceXML applications. A resolution mechanism has been added to handle overlapping cookies with different paths set on a web server - for example, a web server could specify different sessionid cookie headers for two different areas of the site. Existing fetching without paths should be unaffected, but if a user wishes to force use of the old method then they should set the following in $DTJ_HOME/dtj.ini
  wvr.vxml2.FetchSession.ignoreCookiePath=yes
• Increased the default trace buffer size and reduce time waiting if there are no more trace buffers. This does not change the amount of trace written to disk or the size of the trace files on the disk. The change is to handle situations when a lot of trace is being generated and the internal trace system can not keep up. When this happens the tracing routines will slow down causing VRBE to also slow down.
• Fixed an issue where WVR would fail to fetch certain Nuance builtin URIs reporting a FileNotFoundException.
• Fixed a NullPointerException gleaned from using a voice-enabled menu in a document that does not specify 'xml:lang'.
• Fixed dtjit which incorrectly offered en_UK as an option in the Locale field for Add/Change TTS Service and Reco Service panels. This has now been corrected to be en_GB.
• Fixed an issue with very long URI lengths that would cause resource not to be cached for VXML and potentially cause performance issues by altering the way that files are named in the cache. This fix will mean WVR will not use any files cached before this fix is applied.
• Fixed the universals help grammar to work with various speech site documents.
• Updated the dtjes script to delete both old and new style of VoiceXML cache.
• Move some CPU intensive tracing from trace level 8 to trace level 9.

Internal Defect fixes

• Fixed the <menu> VXML element so that Voice navigation of a menu now works correctly with Nuance and Loquendo.
• Improved application error logging and inclusion of document name where missing.
• Fixed an issue with NLSML slot results being presented as conglomerate results if different slot names were used in individual results.
• Fixed an issue where a single result, single slot NLSML-enabled grammar could have the wrong interpretation format.
• Fix to enable the passing of the VoiceXML <mark> element to a speech server in a VoiceXML version 2.0 application.
• Made a change to the <menu> element processing to ensure that the language is sent to the MRCP server if the menu can be navigated using voice.

Internal Defect fixes

• Fixed a NotSerializableException possible with caching Audio files of the form:
  com.ibm.vxi.cachemgr.CacheException: Lost Connection to the VRNode,reason [error marshalling arguments; nested exception is:
  java.io.NotSerializableException: com.ibm.wvr.vxml2.DTAudioProxy]
  at com.ibm.wvr.vxml2.DTAudioProxy.put(DTAudioProxy.java:846)
  at com.ibm.vxi.resmgr.Fetcher.fetchFromServer(Fetcher.java:828)
  at com.ibm.vxi.resmgr.Fetcher.performCachePolicy(Fetcher.java:488)
  at com.ibm.vxi.resmgr.Fetcher.run(Fetcher.java:226)
• Fixed an issue where VoiceXML2 applications invoked from the Java API could fail with a NullPointerException at:
  com.ibm.wvr.vxml2.DTTelServiceSupport.getSessionVar
  (DTTelServiceSupport:210)
• Fixed an issue where CCXML would not use the default port on an outbound <send> HTTP post.
• Fixed an issue with caching long URIs that did not contain a '?', and would instead throw an IOException with the message "Filename was too long to create a file for, name: <URI>".
• Prevented a potential memory leak in the VRNode caused by a gradual increase in thread usage.
• Fixed an issue where VRBE would repeatedly fail to load resources from the cache due to cache corruption. VRBE now forces a refetch of the cached resource.
• Provide parameters to allow a system administrator to limit the number of threads WVR will use when fetching resources on system startup.
  
  The following parameters have been added which should be added to $DTJ_HOME/dtj.ini :
  wvr.vxml2.fetchthreads.limit
  wvr.vxml2.fetchthreads.limit.timer
  
  Where wvr.vxml2.fetchthreads.limit is the maximum number of threads to use (default is 500) and wvr.vxml2.fetchthreads.limit.timer is the time in minutes to apply the limit (default 10 minutes).
  After this time, WVR will revert to the default maximum thread limit. Setting wvr.vxml2.fetchthreads.limit.timer to 0 applies the limit permanently.
• Fixed an issue where CCXML wildcard NumToApp mappings would take precedence over specific VoiceXML or Java API applications. For example, using the following NumToApp mappings:
  NumToApp=111,VXMLApp
  NumToApp=1*,CCXMLService
• Fixed an MRCP resource problem that can result when multiple VXML documents are called from one CCXML document during a single call.
• Fixed a potential StringIndexOutOfBoundsException that could occur is there was an error when using dtjcache to list items.
• Fixed the VoiceXML caching to allow long URIs to be stored (Previously, AIX would prevent any URI longer than 254 characters being stored)
• Fixed an issue which would cause a second instance of connection.connected events to be generated when being moved from one session to another using <move>.
• Fixed an issue where return values from a VoiceXML <exit> would be preserved for a second VoiceXML document used on the same call.
• Fixed CCXML-controlled VoiceXML transfers to be more descriptive in errors. Also fixed dialog.transfer events to contain .uri as per spec, the .URI parameter has been kept for backwards compatibility.
• Fixed an issue where dynamic browsers were not released for five minutes when VoiceXML made a transfer using CCXML.
• Fixed an issue with CCXML <move> that could lead the session.connections entry of a connection to have an inconsistent input and dialogid entry.
• Fixed an issue where <createcall> requests from CCXML could fail when the rest of VRBE was still starting up. Calls would fail with System Failure.

Internal Defects fixes

• Introduced a new dtj.ini paramter 'wvr.vxml2.grammar.fetch.external' to provide an override in WVR for unnecessary grammar fetching/caching when using SpeechServer.
  
  If wvr.vxml2.grammar.fetch.external=false, then http/https/builtin grammars will no longer be fetched by WVR (either at prefetch or during document execution), but they still will be fetched by the speech server. Only file: grammars will continue to be fetched by WVR.
  
  By default this is set to true (current behavior) ie all grammars are fetched by WVR.
• Fixed an issue where cached VoiceXML files would remain in the cache (but be unused ) when the cache control headers were changed to nocache or to have an expires value of 0.
• Fixed a potential NullPointerException when executing a dialogprepare element in CCXML. Note that this would not occur with a straight dialogstart.
• Remove erroneous file from vxi.jar.
• Allow non W3C defined builtin grammars to be referenced within VXML2 documents as supported by Nuance. e.g. CreditCard.
• Fixed an incompatibility issue with Nuance recognition and WVR which could cause an "ERROR: NLSMLException" to be reported in the VRBE log files.
• Fixed an issue where if two VXML dialogs were started sequentially from one CCXML document, when the second dialog was initialised an exception could occur stopping the CCXML application.
• Fixed an issue where self-terminating <send> elements in CCXML documents with space after the / character would throw a StringOutOfBoundsException
• A race condition exists between the starting of the Java Hostmanager and the DTAAlarm process. If the Hostmanager wins the race then errors such as:
  com.ibm.hursley.trace.DTAAlarmQueue.process() NotBoundException java.rmi.NotBoundException: DTAAlarm
  
  are written to the VRBE log file. This fix resolves the race condition and ensures these errors are not logged.
• Under certain circumstances DTAAlarm can terminate with a RemoteException when dtjshost -exit is run. This change prevents this invalid termination from occurring.
• Fixed issue with VoiceXML not getting passed parameters from CCXML intermittently when many VXML browsers are being started. The error seen would depend on what the parameter was being used for, typically with the <value> tag. An example error would be VarScope::eval:The undefined value has no properties.:
  error executing:session.ibm.values.passedInParam
• To avoid JVM errors between multiple AppNodes, the dtjit tool will automatically specify one separate VXML2Cache per AppNode. The error that could otherwise appear is: "Unable to obtain exclusive file lock".
• Fixed a CCXML issue that would occasionally cause a CCXThread.run() error message to report a NullPointerException, stopping CCXML from starting up. This is due to a timing error in sending messages before the internal queues are set up completely.
• Previously the session.uri field would strip forwardslashes from the uri after the protocol, e.g. http://example.com becomes http:example.com. This fix ensures the URI is set to the exact value used to fetch the source of the CCXML document.
• Enables the use of code like the following in CCXML:
  <var name="myHints" expr="new Object()"/>
  <assign name="myHints.CLGN" expr="new Object()"/>
  <assign name="myHints.CLGN._value" expr="'932000'"/>
  <assign name="myHints.CLGN.NUMBER_TYPE" expr="'0'"/>
  <assign name="myHints.CLGN.NUMBER_PLAN" expr="'0'"/>
  <createcall dest="'tel:121281;phone-context=056534'" hints="myHints" timeout="'10s'"/>
  to make a call to an ISDN switch whilst setting multiple parameters, rather than just a single level. (In the example above, setting myHints.CLGN to a simple string rather than a map of several attributes.) The _value part will be turned into the value of the tag by WVR, e.g.
  <`CLGN`=`932000` `NUMBER_TYPE`=`0` `NUMBER_PLAN`=`0`>
• Fixed a problem where <object> element calls to java classes may fail due to tighter rules on class name definitions. This fix ensures that java classes are invoked correctly internally and requires no change to the customers VXML application.

Internal Defects fixes

• Fixed the support of CDR recording of VXML applications.
• The dtaalarm code produced a new log file in $DTJ_LOGS each time the alarm server is started, rather than using existing log file. It should now operate correctly.
• The toString method in DTAAlarmMessage did not check for null params in the param list. If it got one then a null pointer exception occured. This is now fixed.
• DTAAlarmQueue.java required logging of certain failures, which were only traced. The queue should now operate properly.
• Upgraded message displayed by dtjit shown when VRBE tracing is on and VRBE is not running.
• Fixed a StringIndexOutOfBoundsException raised by the VXML browser which could cause the browser instance to terminate.
• Update prerequisite level for Java6.sdk to Service Release 7 (Fix level 6.0.0.175) as it is required to fix memory release problem.. The following URL is a link to the Java 6 APAR:
  http://www.ibm.com/support/docview.wss?rs=1207&uid=isg1IZ67337
• Corrects a mis-spelling in the vrbetrace shell script that meantwhen logging was required from the dtjit utility by setting DTJIT_DEBUG environment variable, if vrbe tracing or logging was modified then the correct java executeable required toexecute the modification was not invoked and the modification.
• Fixed issue when internal components of WVR tried to talk to each other when one had already exited - now they should stop.
• Fixed an issue where dialogs taking a long time to return tried to communicate with connections that no longer exist.
• Fixed a problem with the <break> tag that could be seen when migrating a VXML2 application from a WVR 4.2 system.

VOIP_SIP Fixes

Internal Defect fix

• Corrected a code defect that prevented MWI blind notification from working when using VoIP/SIP.

Internal Defect fix

• Fix MEDIA_CTRL_DTNA restart problem if VOIPL3_SIP crashes. The MEDIA_CTRL_DTNA will now correctly attempt to reconnect to the MRCPrecv and send queues.

Internal Defect fixes

• Some tracing of NOTIFY used some information from the SIP transaction. If the NOTIFY occurs without a proper transaction this can cause a crash. The trace now only occurs if the transaction is valid.
• Stop MEDIA_CTRL_DTNA dropping into the wrong code path when VOIP is shutdown. This was causing error 29800 to be raised.
• Remove a race condition in ES services used by VoIP. This race condition caused error 29106 from es_queue.c
• Remove 100rel from Supported header in outbound INVITE. This can cause the UAS to require 100rel and reliable responses. WVR currently doesn't support this. The result is the 101-199 response is resent until WVR CANCEL's the call.
• Fixed a problem where WVR reports 29805 SIP signalling process error on setRecordRoute for messages that do not have a record route defined. This fix removes the erroneous warnings.
• Fix prevents VOIP_MONITOR from core dumping if /tmp is cleared.
• Register removed from ALLOW as we ignore it, INFO added to ALLOW as we support it, and 100rel added to Supported as we support it.
• Added Accept and Accept-encoding headers as required in RFC 3261.
• Now reject INVITES with no acceptable media types as 488 - not acceptable here, as per RFC 3261.
• Correctly report a busy condition in response to an Options request when no channels are available.
• Fixed provisional responses for calls with a Require: 100rel.

Internal Defect fixes

• Allows "#" in the FROM header in VoIP SIP calls.
• In the case of a SIP blind transfer, if the transfer target did not answer, WVR erroneously logged a yellow alarm id 29805. This error logging has been removed in the no answer case.
• In the case of a SIP consultation transfer using the VOIP_Call_Transfer custom server, if the transfer target did not answer, WVR erroneously logged a yellow alarm errorid 29806 stating 'The outbound transfer call failed to answer'. This error logging has been removed in the no answer case.
• Prevents WVR from including REFER in the ALLOW header when system is configured not to accept incoming transfer requests such as REFER.
• Prevents WVR from attempting an INVITE when making calls to an invalid address
• Fixes error causing SIP_RESPONSE_ADDRESS_INCOMPLETE to be sent unnecessarily when processing a REFER message.
• A REFER message with a Replaces parameter in the Refer-To header now returns a SIP not implemented message rather than address incomplete message.
• Fixes incorrect SDP messages when SIP OPTIONS received, and prevents errors being raised when an OPTIONS message is received before a call is established.
• This fix corrects the o= (owner) and c= (connection info) SDP (Session Description Protocol) header addresses returned in a SIP message to be that of the 2nd network interface when the system is configured to use the 2nd network interface for VOIP SIP messaging. Previously for VOIP SIP calls the default (1st network interface address) was being used in these SDP parameters.

Internal Defect fix

• Remove unused semaphores from VoIP/SIP that were leaking.
