<p class=MsoNormal>Hey guys. Has anyone else experienced the inability to
detect/receive DTMF tones? Just yesterday I had about 4-5 hours where One of
my IVR scripts would not detect 1, 2 or 3, but detected the other digits
perfectly. If I removed the sound file that was playing, and substituted
silence it worked, add the sound file in, and it broke. I have a strong
feeling that this is not an issue with FS, but with an upstream system. But
wanted to know if anyone has seen this before, and how they went about
identifying the culprit and/or fixing it.<o:p></o:p></p>
