Hi Alexander and Patrick,

The debug output would be required to identify the problem. You could enable it from
/etc/asterisk/logger.conf

Nonetheless, I suspect that MRCPRecog did play the specified file. Most probably, the
play was immediately interrupted due to barge-in (START-OF-INPUT from the MRCP server).
BTW, you could try the same with disabled barge-in option (b=0).

The debug output and disabled barge-in option (b=0) logs in attach. disabled barge-in
don't help us ((

Another quest:
We have:
2. File data/sound/palmira3 Format PCM 16bit, mono, frequency=8000, size 133240 bytes

But in Asterisk output we see another file lenght: 
[Jun 15 19:28:17] NOTICE[5251]: app_unimrcp.c:5028 app_recog_exec: file length:66598

it looks like: 66598 = (133240-44(header of wav file))/2(one channel???, but we also
have mono...) We can't understand - what's the matter with it...

What if you try to play one of the standard messages, for instance f=demo-thanks.

Also, you may need to attach that palmira3 file too.

We try file "demo-thanks" and have the same result. Just file lenght now is 38720. Also
we have played both files (demo-thanks and palmira3) with "Playback" function of dialplan
and have success...

I have used the attached palmira3.wav without an issue. So, the problem is definitely
not in the message itself. I started to suspect it's a codec related issue. Try to
use the same codec on both legs: incoming SIP leg and SIP/MRCPv2 leg. Make a network
capture on the Asterisk box and attach it to review.

I think, that problem is in my vmware Ubuntu. Another machine works correctly.
Ok. This bug may be closed in all ;-) Thank you!
