IPCCX - g.729 choppy voice issue

[Henrique Ferreira]

Hello !

I need your help with IPCC using codec G.729.

IPCCX was installed using G.729 but I don't know why, the sound is choppy. Using G.711 it works fine.

Do you think it could be a problem with the .wav file? Any idea?

IPCC Ver.:8.0.2

Call Manager Ver.: 8

Thank you very much.

Where is transcoding going on?  I have had people setup Media Resources and then realize after voice problems they are transcoding or the MTP is nailed up across the WAN on the wrong CUCM server/gateway.   Is this IPCCX virtual or standalone?

Hi Tommer, thanks for replying.

I tried with another g.729 wav file (which was working in a CM) and it worked in IPCCX. Therefore it may be a problem with my converted g729 audio file. Now I want to convert again the raw .wav to g729.

I read cisco documents and i can do that by copying the .wav to CM. The problem I'm facing now is to get the g729 file from the CM to my machine.

the command is :"file get activelog mohprep/FILENAME.wav" (i'm using CM7).

The SFTP server I'm running is Core FTP mini-sftp-server.
Everything goes smoothly, but I'm not sure what I should type in "Download Directory:". I keep getting "Invalid download directory specified" error.

I'm looking for a solution.
thanks!

Fixed.

I used a different software (freeSSHd).
When you get to "Download Directory", just type .

Download Directory: .

Transfer completed.

Using this g.729 that CM converted, it sounds is good.
Thank you very much.
