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.

And I would be grateful if you can give the mail address of the ITU.
Regards,
Rami

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 :-)

Alejandro
