Hi guys
I am doing some troubleshooting at MCP about CPD and need to listen the recoding I have done. However these recordings are g729 ones. So, MCP has some tool or Genesys or any you may know to listen/convert?
I tried some online tools and didn’t work.
Thanks

I know that Genesys PS employees had such a tool some years ago (don’t know if they still do, but I assume they do). If you have a contact with them, try asking for it.
have you tried smzip ?
I have used SOX in the past.
Can you please detail? Can’t find references to SMZIP being able to play wav files
Use Goldwave, it’s free and easy to use.

Gold wave doesn’t support g729 by default. I need the codec

For what I have researched, the patents for Annex A and Annex B of g729 have expired. There is an open source project called bcg729… I will try to play with it to create a tool for conversion (though this might take some time until I finish).
Nice 
will check it out too

Hi Cav,
SMZIP utility i think you can use to change codecs.
I don’t see option to attach the tool here.
Please let me know how can i send it or attach it?
Can you share the download URL? Or send it to [email removed]
Thanks

No clue on how to use that SMzip 
I tried many ways and ended up damaging the original WAV file…
What I ended up doing was to modify the MCP option cpd.record.fileext to mp3, so now I have nice and small MP3 files with AMD recording.
Cheers!
BTW:
If you could post some sample on how to use the SMzip would be nice 
Hi Cav,
Here are the steps. :
Type smzip -ac filename.zip <.wav file name >
for eg if filename is 1111.wav then
smzip -ac g729 1111.zip 1111.wav
It will generate the file in the same path.
Please note:
only 8 KHz mono sound is supported.
Hope it helps .
I still got an error:
SMzip media preparation utility 7.6.009.09 ------------------------------------------ WAVfile(10.wav) incorrect type 0x133 (blk.align=10) ERROR: could not open 10.wav
Still would like a simple way to do this…will keep testing later as probably some day will need a real G729 encoder
Emailed you. Also have decoders for SRTP and AMR-WB/AMR-NB somewhere buried in code for another project.

I was able to use this one as g729 decoder. It has an encoder, but I didnt have the chance to test it yet:
http://www.codecpro.com/LicenseG729.php
it is recomended by freepbx docs for decoding g729 captures:
https://wiki.freepbx.org/display/PC/How+to+decode+and+playback+G.729+audio+streams
(you need Visual C++ Redist 2012 x86 32bits installed)
