AWS Lex Plugin 1.4.0 Released

Amazon Web Services (AWS) Lex Speech Recognition Plugin 1.4.0 to the UniMRCP Server (UMS) has been released.

The plugin is based on the following components:

UniMRCP Server 1.6.0
AWS SDK 1.7.216

The binaries are currently available for the following Linux distributions:

Red Hat / CentOS 7 (unimrcp-lex-1.6.3-1.el7.x86_64.rpm)
Ubuntu 16.04 LTS(unimrcp-lex_1.6.3-xenial_amd64.deb)
Ubuntu 18.04 LTS(unimrcp-lex_1.6.3-bionic_amd64.deb)

This release is built against a newer version of AWS SDK.

With this release, the plugin can be configured to assume a role implemented via STSProfileCredentialsProvider. The behavior is controlled by the configuration attribute 'credentials-provider', which is supposed to be set to 'sts' to use STSProfileCredentialsProvider. Note, in such a case, the attribute 'credentials-file' is not observed.

The release adds support for HTTP proxy in communication with the AWS services and also a license server available as a service.

The detailed list of changes introduced in this release follows.

New Features

Added support for AssumeRole implemented via STSProfileCredentialsProvider. See Sections 3.1 and 4.3 in the Usage Guide.
Added support for HTTP proxy in communication with the AWS services.
Added support for HTTP proxy in communication with license servers available as a service.
Implemented redirection of AWS SDK logs to UniMRCP server logs.

Fixed Problems

None.

Configuration Parameters

Updated the attribute 'credentials-provider' to accept a new value 'sts' next to 'default' and 'custom'. The latter is used by default.
Added a new attribute 'sdk-log-level', which accepts values in the range of 0 (OFF) .. 6 (TRACE).
