Supported Operating Systems

New in This Release

This is a hot fix for this product. This section describes new features that were introduced for this release of Voice Platform PSTN Connector.

This hot fix addresses the issue when the RTP packets from MCP comes in wrong sequence due to network delay. Now the PSTN Connector reorders packets before playing audio correctly to the caller.

• A configuration option was added to the MediaManager section, which you can use to enable PSTN Connector to correctlt reorder those RTP packets.
  
  rtprecvaudiobuffersize
  Default value: 0 (disabled)
  Valid values: 0-no upper limit
  Changes Take Effect: After start or restart

  Recommended setting is 1000; a smaller number may not trigger the packet reordering.
  Set to 0 (or omit) to disable the functionality. (GVP-21257)

Corrections and Modifications

This release includes the following correction and modification:

The PSTN Connector no longer terminates unexpectedly if it receives calls before it has completed initialization. (GVP-20387)

Supported Operating Systems

New in This Release

This is a hot fix for this product. There are no new features in this release of Voice Platform PSTN Connector.

Corrections and Modifications

This release also includes the following corrections and modifications:

The PSTN Connector now returns all received m-lines when responding to the Media Control Platform, and sets the RTP port number to 0 (zero) in the SDP to indicate unsupported media types, prompting the Media Control Platform to disable the corresponding media streams. Previously, this scenario caused the prompt playback to be cut off before completion on outbound calls initiated through the Supplementary Services Gateway. (ER# 289105447)

The PSTN Connector now resets the port state to IDLE at the end of a successful Blind call transfer. Previously, the port state was not reset, causing stuck ports. (ER# 295791816)

New in This Release

This release is under shipping control. There are no new features in this release of Voice Platform PSTN Connector.

Corrections and Modifications

This release also includes the following correction and modification:

The PSTN Connector does not stop streaming in the Dialogic callback thread when the call is prematurely terminated immediately after answer and the first stream buffer is received. Previously in this scenario, the PSTN Connector got into a bad state and stopped responding. (ER# 273272131)

The PSTN Connector now translates all SIP error codes to the appropriate TDM disconnect cause codes. Previously, some of the cause codes were invalid on the Channel Associated Signaling/Robbed-Bit (CAS/RB) configuration, resulting in errors during call disconnection. (ER# 273272137)

New in This Release

This release is under shipping control. This section describes new features that were introduced in this release of Voice Platform PSTN Connector.

• Supports the ISDN Explicit Call Transfer (New Zealand variant).

• Supports the new Use2DigitPortNumber configuration option in the GatewayManager section.

  Use2DigitPortNumber
  Default Value: true
  Valid Values: true, false
  Changes Take Effect: At start/restart

  Use this option to send two-digit logical port numbers in the X-Genesys-GVP-IVRPort header if the configured Dialed Number (DN) uses two digit numbers for its name, or to send three-digit logical port numbers in the X-Genesys-GVP-IVRPort header if the configured DN uses three digit numbers for its name. (ER# 267942115)

Corrections and Modifications

This release also includes the following correction and modification:

Audio packets from the Media Control Platform (MCP) to the PSTN Connector are no longer dropped under high load conditions. This issue has been resolved in this release. (ER# 258240960)

The logging path for the ccilib.*.log has been changed in the log.all configuration option so that logs are now stored in a non-GVP directory. (ER# 268953628)

Known Issues and Recommendations

This section provides the latest information on known issues and recommendations associated with this product.

When PSTNC is run under load on a CAS configuration in a Linux environment, some calls may be dropped before being answered. (ER# 316677971).

Due to third party software issues, the PSTN Connector is not supported on Windows 2008 R2 or Windows 2008 64-bit.

Deploying any GVP Windows IP through Genesys Administrator may occasionally result in the following error, although the actual deployments are completed successfully:

Execution of installation failed. Retcode = 1

(ER# 258776961)

During load testing, the following ec_stream busy error was thrown in TDM channels during media playback:

Got GCEV_OFFERED and media is not idle, forcing media idle. [BrMVoxSt=1] [MVoxFwSt=1 = CS_IDLE] [BrCallSt=Accept].
Stop mvox is pending since 2010/07/06 01:57:56.615
startStreaming: Failed to start streaming for device [0x158]. ec_stream ERROR :: DLGC ERR API dxxxB24C4ec_streamDevice busy
Failed to start Streaming. Bridge Return Code = 8
startMedia: Error during Start Streaming

(ER# 256416618)

Audio packets from the Media Control Platform (MCP) to the PSTN Connector might be dropped under high load conditions. To workaround this issue, decrease the packet transmission rate by changing the value of MCP configuration option [mpc]rtp.prefilltime from 200 to 400.

Note: The workaround might increase the prompt playback latency.

(ER# 258240960)

The audio that is sent by PSTN Connector on the TDM side may have random short gaps. This behavior is intermittent with Dialogic Springware JCT boards only, and may cause incorrect DTMF recognitions at the far end. Dialogic Ticket # C87731. (ER# 247227068, 247135168)

The PSTN Connector does not support SIP over TCP. (ER# 244835768)

The following parameter should be added to Table 25, under the DialogicManager section, on page 195 of the Genesys Voice Platform 8.1 User's Guide:

ATTConfSleepTimeBeforeAnswer
Default Value: 5000
Valid Values: Any integer.
Changes Take Effect: after restart.

Specifies the sleep time, in milliseconds, for the PSTN Connector to wait before connecting the agent and the caller in an AT&T Conference Transfer if using whisper to agent. If not using whisper to agent, set this parameter to 0.
