A new package of Asterisk UniMRCP Modules 1.3.0 has been released and can be downloaded from the following location:

http://www.unimrcp.org/project/release-view/asterisk-modules-1-3-0

Please note that the released source package is no longer shipped with any specific version of Asterisk or UniMRCP, but provides bare modules compatible with a large variety of versions you may choose from, in particular:

• Asterisk 1.6, 1.8, 10, 11, 12, and 13
• UniMRCP r1988 and above (> 1.1.0)

This is an initial release which provides RPMs available to UniMRCP members. As opposed to source distribution, though, binary packages have to be built against specific versions of underlying components. Thus, RHEL/CentOS 6 RPMs built for Asterisk 11.16.0 are currently available and can be conveniently installed using yum. Please note that a complicated chain of dependencies is getting properly tracked and installed by issuing a simple yum command:

yum install asterisk-11.16.0-app-unimrcp-1.3.0-1.el6.x86_64.rpm

and/or

yum install asterisk-11.16.0-res-speech-unimrcp-1.3.0-1.el6.x86_64.rpm

Become a member, ask for support of a particular version of Asterisk/OS you are interested in, and get the RPMs at no additional charge. Furthermore, the members are entitled to request publishing up to four UniMRCP releases per year.

In brief, this release completes support for Asterisk 12 and 13 and also fixes compilation against Asterisk 1.6.0 and 1.6.1 branches. The applications SynthAndRecog() and MRCPRecog() are now capable of playing multiple/mixed prompts. The input timers can now be fully customized.

The detailed list of changes introduced in this release follows.

• Added support for Asterisk 13.

2.1. MRCPSynth()

2.2. MRCPRecog()
