Thanks, do you have any links on how to convert the RTP g.729 into the format that the decoder expects? I would highly appreciate your help.
I don't know the link. But basically you take each bit of the payload,
and convert to a 16-bit word, that is the input of the decoder. It
worked fine for me.
And I would be grateful if you can give the mail address of the ITU
Don't know. Never tried to contact them.

Subject: Re: [Ethereal-dev] G.729
If you are trying to use the G729 payload from an RTP to feed the
decoder that will not work. The decoder is expecting a bit stream, each
bit encoded as a 16-bit word: 0x0071=zero-bit and 0x0081=one-bit
PS: this looks like a question for the ITU mailing list :-)

I wonder if any have any idea about the ITU G.729 sample implementation
sample code. when we use their decoder application, then generated PCM
16-bit file is almost the same size as the input bitstream g.729 file,
and we know that this is a compressed format, is there a problem, or
those samples are assuming something special?
Please help, Thanks
