I would be really grateful for it.

The procedures for getting free ITU documents are given here:
http://marknelson.us/2006/08/10/free-itu-docs/
The G.723 spec includes source code and test vectors, but I don't know
if you can get them with the free download.

| Hello Mark,
Thanks for your message. Please can you guide me to from where I can
get the G723 specs even if it is not for free. What is the procedure to
get it and how much it will cost.
Thanks a lot for your inputs.
Best Regards

Anshul, the original post included a URL that documents the process.
Did you read the article?
Barring the enormous effort of actually clicking on a link and reading
a few hundred words, perhaps you could just go to itu.org and look it
up yourself.
Either way is pretty easy.

| Hello,
I could not open the ftp link you sent me when trying to open it I got
the following error..
An FTP protocol error occurred while trying to retrieve the URL:
ftp://ftp.cs.cmu.edu/afs/cs.cmu.edu...st_adpcm_ccitt/
Squid sent the following FTP command:
CWD afs
and then received this reply
afs is not available to guest users
Your cache administrator is admin.apigmgr@st.com.
can you guide me to how to proceed to the link.
Thanks Anshul

| Hello Mark,
I checked your site and then went to itu.org and downlaoded the SW but
it is huge and I still need to decipher what is required from that for
me. It includes lot many examples other than the G726 implementation.
Thanks a lot for guiding me to itu. It is really really helpful.
Best Regards

For some reason, the highest directory to which you can "cd"
on that server is
/afs/cs.cmu.edu/data/anonftp
Anything higher gives the error message. I can access the site
using the text-mode FTP client that came with Windows, and I
can access it with Netscape, but I don't know about Squid.

You can find the codec and binary lib from http://www.imtelephone.com

| The codec and binary lib are available at http://www.imtelephone.com
but the problem with that is that they are for 16 bit PCM data and the
audio samples available to be after recording are 8 bit companded
(either A law or u law).
Can you help on that. It would be really great.
Thanks & Best Regards
