Corrections and Modifications

This release also includes the following corrections and modifications:


When SIP Server and IP Communication Server (IPCS) are on the same machine, IPCS no longer uses excess memory if SIP Server sends a NOTIFY message and a BYE message at the same time in response to the IPCS REFER message. Previously, in this scenario, the BYE message was processed first and the NOTIFY message was ignored, causing IPCS to use excess memory to store the NOTIFY messages. (ER#s 251966876)


IPCS no longer terminates unexpectedly when it receives a SIP INVITE message with an invalid TO header (for example, To: <sip:<123@10.10.10.1>). (ER#s 261820149)


IPCS now passes the correct frame data when a SIP INFO message is received. Previously, if the codec negotiated between IPCS and Media Gateway was the same as the codec negotiated between IPCS and the ASR Server, incorrect frame data was passed, causing DTMF RTP events to be unrecognizable.

The MRCP server now monitors the Out-Of-Service servers properly. Previously, when the MRCP server was powered off abruptly, In-Service traps were sent incorrectly. (ER# 252791165)


IPCS properly sends the Bargeintype attribute to the MRCP Server when it is set to hotword. Previously, when the Bargeintype attribute was set to Hotword in prompt tag, it was not sent to the MRCP Server. (ER# 247016593)


IPCS no longer stops or skips non-bargein prompts when DTMF digits are pressed. Previously, IPCS skipped the first prompt following an INPUT block if the input digits were more than the maximum digit length. (ER# 249102081)


Call Flow Assistant (CFA) now sends the UPDATE_CALL_STATUS_REQ request to the IVR Server Client in asynchronous mode for a disconnected call. Previously, this request was sent in synchronous mode which caused CFA to timeout if it received a treatment request from the IVR Server Client. (ER# 248100081)

CFA now sends timeouts to PageCollector. Previously, in certain scenarios, CFA could not clear calls that timed out. As a result, CFA did not respond to PopGateway call-in progress messages, and these calls were dropped. (ER# 242271959)


IPCS now checks for the key-ahead digits in the tone buffer before starting the prompt play. Previously in an ASR disabled application, if the input for a barge-in enabled prompt was given before the prompt started, the barge-in was not recognized immediately and the entire prompt played. (ER# 239697196)


PopGateway now shuts down properly when a graceful shutdown command is issued while a REGISTER message is being sent. Previously in this scenario, PopGateway would exit unexpectedly. (ER# 239710881)

Corrections and Modifications

This release also includes the following corrections and modifications:


In behind-the-switch configurations, the Backup Dispenser can now be configured in Call Flow Assistant (CFA) using the DID.xml URL in case of failures parameter—for example, http://<Backup_Ini_Dispenser_Machine>/$did$.xml. For more information on the DID.xml URL in case of failures parameter, see the "Configuring IPCS in the EMPS" chapter in the Genesys Voice Platform 7.6 Deployment Guide. (ER# 240017087)


The SIP response code that is sent by the IPCS when its ports are unavailable is now configurable. On the PopGateway node in the Element Management Provisioning System (EMPS), the NoChannelsResponseCode parameter can be set to a value between 400 and 699. Previously, when IPCS ran out of available ports, and a new call INVITE message was received, it sent a single SIP 486 response only. (ER# 236969999)


IPCS now sends RTP data to the IP address of the MRCP server that is negotiated by the SDP. Previously, under load conditions, IPCS would send data to the incorrect MRCP server. (ER# 237163383)

Corrections and Modifications

This release also includes the following correction and modification:


When PopGateway is playing multiple files, start-of-speech events are now reset only at the beginning and end of Automatic Speech Recognition (ASR). Previously, if a start-of-speech event occurred between the prompt that was playing and the next prompt to be played, PopGateway did not wait for the ASR results, which caused the call to hang indefinitely.

Corrections and Modifications

This release also includes the following corrections and modifications:


In behind-the-switch mode, if PopGateway is not able to fetch the DID.xml, it fetches the fallback DID URL from the CC_EXCEPTIONMAP. Previously, PopGateway would check the EXCEPTIONMAP and fetch the error URL. (ER# 229151758)


When using Native RTP, IPCS now accepts multiple termination characters when detecting DTMF. Previously, IPCS would only recognize the first termination character in the list of characters, which caused incorrect handling of calls. (ER# 230349503)


Whisper-to-agent now plays successfully when a second call is placed to IPCS. The fix sets the string that contains the downloaded file name to empty and retrieves the file name from the proper source during the second call. Previously, after the first call, the downloaded tmp file in the cache was deleted, but the index that pointed to the deleted file path in the cache was not updated. This caused the previously deleted file in the cache to be used for the second call. (ER# 228097324)


IPCS ports no longer appear out-of-service when SIP Server performs a primary/backup switchover. Previously, during SIP Server switchover, IPCS did not clear failed REGISTER responses from its internal list, resulting in out-of-service ports. (ER# 232389263)


In behind-the-switch mode, the previously posted session variables are no longer lost while performing a synchronous record post. (ER# 232731379)

Corrections and Modifications

This release also includes the following corrections and modifications:


IPCS now sends the SIP REGISTER message with two contact headers. The first one carries the contact address of the primary SIP Session Manager (SSM), and the second one carries the address of the secondary SSM. This behavior is configured by enabling the AllowSIPRegMultipleContacts when configuring IPCS with primary and backup SSMs. Previously, in an HA configuration, and using an Avaya SES switch, IPCS sent only the contact header of the primary SSM, and if the primary SSM was unavailable, calls were dropped because an alternative contact address was not specified. (ER# 44375991)


IPCS now detects DTMF when receiving calls from an Avaya Switch. Previously, DTMF was not detected when the Avaya Switch sent a ReINVITE with an empty SDP to IPCS. (ER# 173245127)


IPCS now supports call flows received from Alcatel OXE 4400 and OXE 9.0 switches. (ER# 223111894)


IPCS now sends and receives RTP data from different NICs on the same machine. (ER# 218539461, 220128333)


For Outbound calls, IPCS now sends the telephone-event with the configured payload type. (ER# 221003116)

Corrections and Modifications

This release also includes the following correction and modification:


IPCS now supports multiple DTMF tones using the same time stamp in the RTP header with the new multidtmf_one_timestamp parameter. If this parameter is set to a value of 1, the end bit is used to differentiate the DTMF tones, and the timestamp is ignored. (ER# 233715951)


IPCS now correctly receives the Connection Disconnect Hangup event from the subdialog application while executing AT&T transfers. Previously, when Transfer Connect was executed as part of a subdialog, and that subdialog executed the <return> element, the page transition manager did not return control to the main dialog page. (ER# 233750561)


When using multiple NICs, Call Flow Assistant (CFA) no longer associates the hostid to second NIC IP instead of first NIC IP by setting the localIPAddress parameter. This parameter provides the IP address to be used when generating the unique ID. If not set, CFA uses the first IP address returned by the OS. (ER# 234352704)

Corrections and Modifications

This release also includes the following corrections and modifications:


SIP INVITE requests sent to IPCS without Session Description Protocol (SDP) information no longer result in stuck virtual ports when there is a problem creating the media path. IPCS now sends a SIP 500 Server Internal Error message when it fails to create the media path with local SDP information. (ER# 219476195)


IPCS now captures the Local IP address configured in the MCU section and sends it in the SDP of the 200 OK message. (ER# 219027263)


IPCS no longer executes the sysroot catch handler instead of applicationroot catch handler when the caller hangs up while sending a SIP INFO message. (ER# 220070861)


IPCS now updates the Total Outbound Calls Rejected value when the connecttimeout parameter expires before it receives a 4xx response and IPCS returns a NO ANSWER. (ER# 101378759)


IPCS now looks for the java script files in the correct directory. Previously, if the main VoiceXML application had a root page document residing in another directory, and the root page referenced a java script file (for example, <script src=""xyz.js"/>), GVP looked for the file in the main application directory instead of the root document directory which caused a url fetch error. (ER# 216875770)


For Outbound calls, voice applications that use the transferaudio parameter will play audio for consultation transfers as well as for bridged transfers. Previously, in this scenario, audio played for bridged transfers only. (ER# 112782653)


PopGateway no longer fails during Registration when the SIP start Channel Id is set to a very large number. (ER# 212235387)


When using the TlrRegisterResource method, IPCS now specifies the correct starting port number. (ER# 197320498)


IPCS now waits for the termination digit during a bargein. (ER# 212395500)


IPCS no longer skips playing the audio file when cleardtmfbuffer parameter is set to false and DTMF input is stored in the DTMF buffer. (ER# 215893354)


PopGateway provides a configurable parameter DefaultMediaFormat, which specifies the default format for audio prompts. If the VoiceXML application does not specify the prompt format with the com.telera.audioformat extension, the value specified with the DefaultMediaFormat parameter is used. Previously, if the format was not specified using the com.telera.audioformat extension in the VoiceXML application, IPCS played the prompts using the μlaw codec. (ER# 218932501)


IPCS now accepts the entire RTP header which conforms to RFC[3550]. Previously, IPCS received RTP packets that contained the basic (the first 12 octets) part of the header only. If the header contained CSRS identifiers, MCU would unexpectedly exit. (ER# 216963414)


The third-party memory management application, SmartHeap 7.x, has been upgraded to version 9.0. Previously, if the VoiceXML file included a large number of JavaScript functions embedded in a CDATA section, SmartHeap caused the memory usage to spike in the PopGateway, and IPCS terminated unexpectedly. (ER# 216509954)


The MRCP Client now validates the cnmrcp pointer before processing the socket reset connection event. Previously, when a 408 Timeout error occurred, the MRCP Server closed the connection, and when the MRCP Client attempted to access the cnmrcp pointer, the MCU process terminated. (ER# 217418445)

Corrections and Modifications

This release also includes the following corrections and modifications:


IP Communication Server (IPCS) now correctly disconnects a bridged transfer when the caller hangs up while the Agent's phone is ringing. (ER# 195762501)


Session parameters are now passed to MCU during a retry or a redirect call. Previously, when an outbound call failed with a 480 error, and GVP was configured for retry using the sip4xxretrycode parameter, on the redial, session parameters were not passed which caused IPCS not to play the Text-to-Speech (TTS) prompts. (ER# 214849811)


When using Host Media Processing (HMP), IPCS no longer passes the incorrect shadow variable after a DTMF termination. Previously, the shadow variable returned message$.termchar = undefined instead of message$.termchar = dtmf. (ER# 212263912)


When in behind-the-switch mode, Call Flow Assistant (CFA) now sets the local exception map when returning the DNIS to PopGateway. Previously, in this scenario, CFA set the global exception map which caused PopGateway to fetch unknowndnisurl when receiving a BAD_XMLPAGE error. (ER# 198815411)


HMP IPCS now correctly orders the codec list in the 200 OK response to an INVITE message. (ER# 137493241)


SIP INFO variables are now created in all execution contexts. Previously, SIP INFO variables were only created in the main execution context which caused the subdialog execution context to return undefined values when attempting to access the session variables from the main execution context. (ER# 204576095)


For OBN calls, CFA no longer writes unnecessary outbound messages in the logs when Policy Manager is disabled. (ER# 211682264)


IPCS now performs case insensitive string comparison when clearing the buffer of DTMF tones. Previously, when the speechenabled parameter was set to true, the prompts were skipped if DTMF tones were found in the buffer. This caused the IVR application to generate errors and not continue. (ER# 207516248)


HMP IPCS no longer waits for the time set in the interdigittimeout parameter to expire when the expected input is one digit. (ER# 209206759)


IPCS no longer waits for the time set in the termtimeout parameter to expire when the termination character is received. (ER# 209206531)


IPCS no longer sends the BYE response without setting the Max-forward headers in the SIP message.(ER# 191423841)


When using Nuance 8.5, IPCS now returns a matched result for the formitem variable name. Previously, in this scenario, IPCS sent Object Object for this variable. (ER# 202130454)


IPCS now clears the Automatic Speech Recognition (ASR) DTMF buffer when it receives an ASR error. Previously, for menu based applications, the ASR DTMF buffer was not cleared if an ASR error was encountered. This caused the call to continue instead of terminating. (ER# 204584491)

Corrections and Modifications

This release also includes the following corrections and modifications:


IPCS now accepts the timeout attribute in the <nomatch> tag. Previously, the timeout attribute was replaced with the default system root timeout of three seconds, which did not allow the use of the timeout attribute in the catch handler. (ER# 172634711)


IPCS now generates an error.connection.baddestination event when the destination URI is either malformed or invalid. Previously in this scenario, the error.unsupported.uri event was generated. (ER# 176802311)


IPCS no longer fails to register with Nortel switches. Previously, the registration failed because the from header in the REGISTRATION message was different than the to header. (ER# 181462283)


IPCS now generates a connection.disconnect.transfer event for successful consultative transfers. Previously, the connection.disconnect.hangup event was generated. (ER# 179789928)


When IPCS is situated behind IP Call Manager (IPCM), PopGateway now waits for a response to the unregister successfully message before shutting down the SIP stack. Previously, PopGateway would shut down the SIP stack after the successful unregistration message without waiting for a response. This caused PopGateway to generate an exception to a graceful shutdown. (ER# 185899676)


IPCS now negotiates the RFC2833 DTMF events for dynamic payload 127. (ER# 189391254)


IPCS now recognizes DTMF and ASR when working with Nuance Quantum NSS 5.0.4 and Recognizer 9.0.5 speech engines. (ER# 198279101)


When using the bargein hotword, IPCS now skips the remaining prompts in the list. Previously, all prompts in the list were played after the bargein was encountered. (ER# 196646204)


The SWMS server no longer stops when Host Media Processing (HMP) IPCS uses the G729 or G723 codecs. (ER# 173245568)

For an incoming INVITE that contains unsupported content, IPCS now sends a 415 Unsupported Media Type with the Accept header values of application/sdp, application/dtmf, and application/dtmf-relay. Previously, if the incoming INVITE contained unsupported content (for example, Nortel CS100), IPCS returned the 415 Unsupported Media Type message without the above Accept header values which caused IPCS to retransmit the same INVITE without recognizable content.

The operating systems supported by this release are listed in the Contents, above.

New in This Release

This release is under shipping control. This section describes new features that were introduced in the initial 7.6 release of Genesys Voice Platform IP Communication Server.

Corrections and Modifications

This release includes the following corrections and modifications that were made between Release 7.5 or earlier releases and the initial 7.6 release:


When the speechenabled parameter is set to false, and the <screxpr> grammar tag is used, the VoiceXML interpreter no longer generates an error. Previously in this scenario, the VoiceXML interpreter evaluated the grammar URI as an empty string and generated a badfetch error. (ER# 122376701)


IPCS with Host Media Processing (HMP) can now play A-law media files. Previously, IPCS with HMP could only play Mu-law media files. Also, if an A-law media file was played while using HMP, there was a lot of noise in the background. (ER#  130928101)


When using IPCS with HMP, in a VoiceXML application expecting ASR or DTMF input, the timeout timer now starts after the prompt finishes playing. Previously, the timeout timer started as soon as the application started playing the prompt inside the menu/input block, which resulted in IPCS generating a noinput event before the caller had a chance to provide input. (ER# 162300653)


IPCS now supports sending the PRACK (Provisional Response ACKnowledgement) SIP message in response to a 183 Session Progress message sent by a Media Gateway. You must set PrackSupport=1 in the PopGateway section of an IPCS node in EMPS to make use of this correction. Previously, even if PrackSupport was enabled, no PRACK message was sent when a 183 Session Progress message was received. (ER# 119929963)


The format of the audio file, as specified in the VoiceXML application, is now properly sent to the Media Control Unit (MCU). Previously, a crackling sound was heard at the beginning of audio file prompts playback if the format was specified in the VoiceXML application. (ER# 136368711)


IPCS can now detect a tone to be valid even when it receives a single RFC 2833 RTP tone packet, which enables interoperability with SIP phones and media gateways that do not generate repeated tone packets. You can enable this option with the configuration parameter ToneDetectionOnFirstPacket. (ER# 137252181)


IPCS now supports pre-connect (early) CPA detection. (ER# 134300309, ER#  110844577)


IPCS now supports hotword recognition after the call is bridged. (ER# 111943309)


OBN OCS now works properly when IVR Server Client is turned on for the application. (ER# 126316739)


The caller and the agent are now disconnected if REFER time outs (NO_ANSWER) in Consultation transfer. Previously, they were not disconnected. (ER# 117645684)


GVP now evaluates the relative URL when it is sent to MRCP server. (ER# 122338754)


IPCS now sends the SIP register message to the configured register port. Previously, IPCS was sending it to the default 5060 destination port. (ER# 124700541)


IPCS no longer reports the second re-invite to TelephonyController as an earlier event than the first ACK, when both SIP messages arrive at almost the same time. (ER# 129026811)


Code Tracer now works with GVP. Previously, TXML caching was removed for all pages that had a sessionid string, but before answering the call, when the first IVR page was fetched and parsed, the TXML action BeginSession object was not handling the scenario where the page was not retrieved from the cache. This resulted in the call getting dropped without executing the IVR. (ER# 130082131)


IPCS no longer throws an error during a Consultation transfer load. (ER# 129017477)


A crackling noise is no longer heard between prompts when there is user input required. Previously, when playing successive prompts that required user input, a crackling noise was heard before each prompt. (ER# 137252190)


PopGateway no longer throws a parse error while parsing the response page from the OBN manager when it is on the same host. Previously, PageCollector was adding an extra null character to the end of fetched data during a internal (COM\SOAP) call. (ER# 120061039)


IPCS now waits for the duration of termtimeout for the DTMF input to finish when no ASR is used and the termchar is defined as #. Previously, IPCS did not wait for termtimeout when the maximum digits were entered and the termchar was #. (ER# 137252197)


The prompt on the caller leg is now played before transfer when the Wait While Dialing feature is disabled. (ER# 31685333)


IPCS no longer disconnects the caller leg if the bridge is unsuccessful. Previously, IPCS would timeout on failure to complete a bridge successfully and would hang up the outbound leg by doing an unbridge, but never terminated the inbound leg. (ER# 55464953)


You can now hear the beep sound when beep="true" in <record>. (ER# 65490151)


IPCS now recognizes a DTMF tone from the CCAS/Stream Manager. (ER# 81403031)


During bridge transfer on HMP, if the endpoints of the two call legs do not support at least one common codec, the bridge transfer no longer fails. (ER# 99750156)


IPCS no longer hangs up the call when IPCS sends DTMF to the far end as SIP INFO and the far end does not respond, resulting in a timeout. (ER# 109291231)


If the invite to the enhanced Media Server fails, IPCS now returns the same 4xx or 5xx response for that invite to the caller. Previously, IPCS returned 415 media not supported to the caller. (ER# 124666503)


IPCS now sorts the negotiated codec list in the order of the far end SDP’s codec list. Previously, IPCS did not order the negotiated codecs correctly in 200 OK in response to INVITE. (ER# 137493241)


IPCS now distinguishes between the first leg and the second leg participating in the bridge, and IPCS can now compare two codec lists. Previously, when default remote bridging was attempted, the bridging failed due to a lack of common codecs. (ER# 93798941)


IPCS now sends BYE to the caller in order to disconnect the caller's leg. Previously during bridging, IPCS sent reINVITE continuously to the outbound leg. (ER# 78737)

While using Convedia, the beep sound is not heard even when beep="true" in <record>. (ER# 155631014)

Found In: 7.6.001.80 Fixed In: 

The record shadow variable returns “message$.termchar” = “undefined” after DTMF termination. The result should be a DTMF value. (ER# 168014083)

Found In: 7.6.001.80 Fixed In: 7.6.410.17

When using OSR 3.0.x and Nuance Recognizer 9.0.x, IPCS throws a no-match error when field type="currency" and the input is seven digits or higher. OSR 3.0.x and Nuance Recognizer 9.0.x should support up to nine digits. (ER# 170769049)

Found In: 7.6.001.80 Fixed In: 

For Host Media Processing (HMP) bridged calls with active hotword, IPCS does not send audio to the Agent if the caller puts the call on hold with SDP a=sendonly. (ER# 108054992)

Found In: 7.5.003.60 Fixed In: 7.6.001.80

IPCS cannot set the refresher parameter to UAC in the 200 OK message if the refresher parameter is present in the session-expires header of INVITE. The refresher parameter will always be set to IPCS. (ER# 99228428)

Found In: 7.5.000.60 Fixed In: 7.6.200.37

If text between <mark> tags is a few words only, the correct <mark> tag may not be returned. (ER# 63936764)

Found In: 7.5.003.60 Fixed In: 

When using the Session Timer, IPCS does not support sending or processing the 422 error code. Therefore, if the far end responds with the 422 error code to an outgoing INVITE, IPCS ignores the min-SE and continues using the same Session-Expires header, so new sessions cannot be initiated. As a workaround, configure the Session Timer Interval (secs) parameter to the minimum min-SE header field value expected to be received by IPCS in a SIP session. (ER# 24345101, ER# 101360696)
