I had a company make some g.729 audio files, but the 7100 uses the g.726.
I cannot find a converter anywhere, so I am hoping someone here can help me out.
I used to use smart wav converter, but that site is no longer.
ANy help would be appreciated. Thanks in advance.

Try switch by nch software.
I never converted from g729 though. You may need to get them as wav/mp3 from the company
