• Links in the Contents section enable you to access information regarding a specific release. Releases are listed by version number rather than in date order. For this reason, a recent release may be listed after earlier releases, if the version number is lower. Except when otherwise noted in the information for a specific release, each release includes all of the features and corrections that were introduced for the applicable operating system at earlier dates, regardless of the version numbering.
• The Release Number table lists the supported operating systems for each release at a high level. For more detailed information, see the Genesys Supported Operating Environment Reference Guide.
• The Known Issues and Recommendations section is a cumulative list. It includes information on when individual items were found and, if applicable, corrected.
• The Corrections and Modifications section for each release may list additional issues that were corrected without first being documented as Known Issues.
• The Discontinued Support section is cumulative. It lists functionality that is no longer supported and the release number of the version in which support was discontinued.

Supported Operating Systems

New in This Release

This release is under shipping control. This section describes new features that were introduced in this release of MRCP Proxy.

• MRCP Proxy supports primary/backup speech server list.
• MRCPP will route requests to speech servers based on authorized ASR/TTS engine names passed by MCP.

Corrections and Modifications

This release includes the following corrections and modifications:

The following problem is solved: When MRCP Proxy was configured as HA pair (active-standby) and during initialization, MCP connected to the standby MRCP Proxy first, the proxy instance accepted the MCP connection and then immediately disconnected (as running on standby mode). However, as MCP was not fully initialized yet, it failed to handle the disconnect. As a result MCP was not aware of the disconnect and did not perform failover to the active MRCPProxy. (ER# 304105231, 304105221)

Supported Operating Systems

New in This Release

This release is under shipping control. This section describes new features that were introduced in this release of MRCP Proxy.

• 32-bit and 64-bit GVP application binaries are available for Windows and Linux 32-bit operating systems and 64-bit operating systems, respectively.
• Dual stack IPv6, IPv4.
• Resource selection and call rejection, based on MRCPv1 speech resource and availability.
• Nuance Recognizer 9.0.18 and Vocalizer 5.0.5 with NSS 5.1.5 MRCP Server v1.
• This release adds ADDP trace support to the CCILib library, so that any Genesys Voice Platform component which uses CCILib will print the corresponding trace logs when configured to use ADDP.

Corrections and Modifications

This release includes the following corrections and modifications:

When the Genesys Voice Platform MRCP Proxy is started, the build information is printed in its log file in the following order:

1. The Management Framework libraries and their build versions.
2. The GVP common library and the corresponding component and their build versions.
3. Other third-party dependencies without the version information.

Note that in the Linux operating system, if the ident utility is not installed, then the MRCP Proxy versions are not printed. (ER# 284220141)

The Genesys Voice Platform MRCP Proxy no longer creates a Windows registry entry each time it is started. Now, one entry is created the first time that MRCP Proxy starts after it has been installed. (ER# 281806924)

The Genesys Voice Platform MRCP Proxy no longer incorrectly sets the port to zero in the outgoing INVITE's Via header when sip.transport.x is configured with an actual IP address. (ER# 281245911)

The Genesys Voice Platform MRCP Proxy now sends a 404 response to Media Control Platform (MCP) as soon as the PING request to MRCP servers fail and MCP sends TEARDOWN to MRCP Proxy. Previously, when the MRCP Proxy was connected directly to the MRCP server and the connection failed, it did not immediately notify the MCP of the failure. Therefore, the MCP did not immediately generate an ASR/TTS error. (ER# 270328551)

Known Issues and Recommendations

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

In RHEL 6.x, MCP and MRCP Proxy should not co-exist in the same machine. Performance suffers.

Workaround: Specify that the MRCP Proxy listen on a port that doesn't conflict with other ports / port ranges in various GVP components residing on the same machine. (GVP-20268)

When Nuance Speech Servers are overloaded and are running out of licenses, they return the message 500 Server Internal Error for any subsequent requests from MRCP Proxy or MCP—and the request fails.

Workaround: Provision Nuance licenses based on the expected capacity of the deployment—the number of peak concurrent GVP ports that use ASR and TTS—so that the Nuance Speech Servers do not run out of concurrent licenses. (ER# 303031051)

When MRCP Proxy is configured as an HA pair (active-standby), and MCP connects to the standby MRCP Proxy first during initialization, the proxy instance accepts the MCP connection and then immediately disconnects (because it is running on standby mode). However, because MCP is not fully initialized yet, it fails to handle the disconnect correctly. As a result MCP is not aware of the disconnect and does not perform a failover to the active MRCP Proxy. (ER# 304105221)

When MRCP Proxy is loaded with heavy traffic and Nuance MCRP and License Server(s) are re-started, the proxy may terminate while cleaning up existing sessions with the disconnected servers. Genesys recommends that you alter licenses or other configurations for the Nuance Servers when MRCP Proxy is not loaded (e.g., during off-business hours or a maintenance window). (ER# 303370657)

When the MRCP Proxy is connected directly to the MRCP server and the connection fails, it does not notify the Media Control Platform of the failure immediately. Therefore, the Media Control Platform does not generate an ASR/TTS error immediately. (ER# 270328551)
