This release introduces revamped configuration format. The new format allows to use profiles in more flexible way. Also, it addresses XML conformance issues. Corresponding XML schemas are available as well. Please upgrade your local configuration files as the old format is no longer valid.

The other major addition is the implementation of request timers. It aims to address a potential vulnerability of the UniMRCP client stack in case there is no response back from an MRCP server. RTSP, MRCPv2 request timeouts as well as several SIP timeouts are configurable now.

Yet another interesting addition is an utility tool called svnrev, which allows to generate uni_revision.h header file containing SVN revision number and build stamp. Although this tool has basically been integrated into VS and GNU build, it's experimental and probably informative only yet.

Changes since previous release 0.9.0 r1383 include

• Enhanced MRCP, RTSP parsers to be able to process messages with headers, which don't entirely fit the read buffer. The issue encountered on processing of a huge number of vendor specific parameters included in the response to GET-PARAMS request. (Issue-57, Vlad)
• Disabled simultaneous termination of tasks. Now tasks are terminated one by one. (Issue-56, Derik)
• Fixed apt_pair_parse() to copy name/value strings from the stream.
• Fixed possible stack overflow on the construction of log entries. Log entries are limited with 4096 bytes.
• Added a sample scenario to umc application to show how SET-PARAMS and GET-PARAMS methods should be used.
• Fixed RTSP client stack crash while processing the response to final TEARDOWN request. (Issue-60, Chris)
• Provided an option to adjust size of buffers used to receive/transmit MRCPv2 messages. (Issue-57, Vlad)
• Added the main page for doxygen generated documentation. (Vali)
• Implemented an option to trace current thread identifier in the logs. (Anthony)
• Checked playout delay to be codec frame aligned. (Shy)
• Fixed remote address in the trace for "Close RTP Transmitter".
• Revised C/C++ header guards not to violate naming convention of the C standard. (Issue-62, Markus)
• Added SVN keyword Id to all the source files to be automatically expanded on each commit with the revision number and stamp of the file.
• Fixed access violation while reading server config. (Issue-66, Vali)
• Enhanced detection of Flite configuration. (Issue-67, nombrandue)
• Added logger.xml configuration file to load the settings of logger from.
• Added missing mpf_codec_open() and mpf_codec_close() calls, which might be required for integration of new codecs. (Shy)
• Added multipart content generator and parser.
• Enhanced asrclient library built on top of libunimrcpclient to provide streaming interface as an alternative to file input.
• Introduced generic timer queue and poller task.
• Removed no longer referenced net client and server tasks.
• Fixed UniMRCP server crash in case there is no MPF engine configured for the MRCPv1 profile. (Issue-74, Anthony)
• Increased XML_FILE_BUFFER_LENGTH to ensure configuration files fit the buffer.
• Revised task and inter-task communication related debug traces.

Thanks for using UniMRCP.

I would like to announce the second release of UniMRCP connector bridge for Asterisk.

The connector bridge is prepackaged with Asterisk-1.6.1.14 and UniMRCP-r1456 (> 0.9.0). These are the recommended versions to use, though other versions are also supported.

This release contains a few enhancements in speech resource module (res_speech_unimrcp), which implements the Generic Speech Recognition API of Asterisk.
* Added internal configuration file (/etc/asterisk/res-speech-unimrcp.conf) with further reference to UniMRCP client configuration.
* Supported various recognition grammars including builtin grammar, text/uri-list, multipart/mixed and everything else.
* Added an option to preload grammars for a channel
* Added an option to set properties (MRCP header fields) for a channel

It also introduces a new and great application module (app_unimrcp) gracefully contributed and actively maintained by J.W.F. Thirion <This email address is being protected from spambots. You need JavaScript enabled to view it.> Molo Afrika Speech Technologies (Pty) Ltd.

Asterisk dialplan applications are:
* MRCPSynth - text to speech,
* MRCPRecog - speech recognition


The released package can be downloaded from
http://unimrcp.googlecode.com/files/uni-ast-package-0.2.0.tar.gz

For the installation, configuration and usage please refer to the wiki page

This release introduces new major features such as
- Implementation of MRCP recorder resource
- Support for RFC4733/RFC2833 out-of-band and in-band DTMF generation and detection
- Implementation of RTCP stack (Nuance compliance)
- Support for 64-bit platforms


For the first time 64-bit Windows binaries are available as well. Please note, 64-bit UniMRCP can be installed only on 64-bit OS, while 64-bit UniMRCP SDK can be installed on both 32-bit and 64-bit. This allows you to develop 64-bit applications even on 32-bit OS.


Changes since previous release 0.8.0 (r1199) include
- Added compile time define to support "too long" MRCP request identifiers (Issue-48, Vali)
- Fixed race condition on client stack initialization (Issue-49, Aabaziev)
- Re-factored abstract MRCP resource entity
- Loaded MRCP resources from config (unimrcpclient.xml and unimrcpserver.xml must be updated)
- Added a few accessors to mrcp_application interface in order to completely hide session interface from the application context.
- Properly processed nua's shutdown (John)
- Fixed function prototypes to compile without warnings with -Wstrict-prototypes gcc option (John)
- Fixed a few RTSP/MRCPv1 session management related issues (Issue-51, Vali)
- Fixed core dump with large in-line grammars (Issue-52, Asackheim)
- Added recorder plugin and sample recorder scenario/session
- Added DTMF generator and detector (Vali)
- Added sample DTMF recognizer scenario/session
- Reworked timer/clock related entities, added scheduler entity
- Fixed build warnings from sun studio (Mike)
- Supported both synchronous and asynchronous start of client stack.
- Fixed memory (resource) leak on client/server task termination. Threads MUST be detached first in case of async task termination (Issue-53, Derik)
- Installed uni_version.h alongside with other header files required for the integration
- Added x64 platform configuration to VS2005 build
- Fixed compilation warnings using 64-bit compilers
- Updated inno-setup scripts to be able to build both win32 (x86) and x64 (x86-64) installers.


Thanks for using UniMRCP.

Happy New Year!
This is the greeting, which is likely said and heard many times during the days.
It's a good tradition and time when we may summarize activity done during the previous year and setup some goals for the new year.

The project continued to evolve during 2009, despite of the global financial crisis and resulted difficulties.
There were scheduled and periodically released five versions of UniMRCP, which introduced new features, provided bug fixes and ensured stability.
Integration with well know open source telephony platforms, utilization by several corporates, support contracts, custom development options and my strong desire keep the project going. This makes me think about the first major release of UniMRCP in 2010, which would be another value added release indicated a certain milestone. I'll follow up with the next 0.9 version during the days and come up with a few suggestions, proposals thereafter during this month.

Also it seems I've got another good tradition to polish the website of the project a bit during the holidays. Please checkout the new face.

Let it be a successful and prosperous year for all of us!
