Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.Install latest uni-ast-package with all components, and lumenvox server with 
sppech recognition license
2.Configure basic lumenvox conection 
(http://www.lumenvox.com/knowledgebase/index.php?/article/AA-01129/0)
3. Test asterisk with a simple dialplan 
(http://www.lumenvox.com/knowledgebase/index.php?/article/AA-01130/0)
4. Asterisk restart and it seems to send a TEARDOWN RTSP message at the 
beginning:

Here asterisk restarts.

What version of the product are you using? On what operating system?
I'm using uni-ast-packege-1.2.0, and the latest lumenvox.

Please provide any additional information below.
I tested the lumenvox ASR and media server using unimrcpclient program and it 
works fine, but with asterisk it doesn't work. I also tried with uni-ast v1.0.0 
and v1.1.0 and the result is the same. Attach asterisk verbose and debug, and 
lumenvox debug.

version 1.1.0 works.

As far as I can see, although an MRCPv1 profile was used with MRCPRecog(), the 
MRCPv2 agent was still somehow involved in session initialization, which is 
definitely not the expected behavior.

I'm not even sure whether this can be a configuration or build issue or 
anything else. As the next step, can you provide additional information such as 
configuration and build related details (Linux, gcc version,...).

I'm using Centos 6.5, kernel 2.6.32-431.20.3.el6.x86_64, I use 
gcc-4.4.7-4.el6.x86_64 to build uni-ast-package-1.2.0. I send you all the 
configs. Thank's for the response....please tell me if you need more info

It looks like app_unimrcp loads MRCP version 1 profiles incorrectly (MRCP 
version 2 profiles are not affected).

I had made a few related changes in the client stack recently which were 
included in UniMRCP-1.2.0 release. The client stack itself is not affected, 
both v1 and v2 profiles work as intended. However, app_unimrcp needs to be 
patched.

Temporary workarounds:

1) Use MRCPv2 instead of MRCPv1
or
2) Use unimrcp-1.1.0 with the latest Asterisk modules 1.2.0
or
3) Downgrade to uni-ast-package-1.1.0 completely
