Hello, I have a Call Studio 8.5(1) application that uses the Record element and FTP element to record and save a customer recordable prompt that is played as an "upfront greeting" in an ICM script.  The application records the prompt and sends it via ftp to four CVP/Media servers and always appears to compete successfully according to the VXMLserver application activity logs. However we are having a problem where occasionally, the recorded prompt will not play and upon examination, using a couple different RIFF file viewers, I have confirmed that when the problem occurs the new prompts on all four media servers have invalid RIFF headers in the prompt WAV file.  The RIFF editors report "invalid file length" and cannot identify the file format.  If I open the file in Goldwave, a digital audio editor, it also cannot read the RIFF header ands sees the file as a RAW file and asks for the format to open it. If I specify that the format is  u-Law 8-bit mono, the file opens and the audio is intact.  If the customer re-records the prompt, it normally will work.  I am wondering if anyone has experienced anything similar.
