Hey Gale .. figured out the answer .. it was mostly just me being a bonehead user.
Yes .. they require a u-law, 8Khz, 8-bit, mono configured wav file .. I was not properly setting it to 8000 (8K), and was not exporting out as u-law, in the other compressed formats. Once I did this, all of my changes were there properly, and the static was gone. Happy customer .. and I now can easily do this for any of my Business Voice Edge (BVE) customers. You didn't really answer my question, but you did force me to look inside and seek the answer, so thank you
