Sound file stops playing

Hi,

I have ast 1.2.30.2 with zaptel running. I am using it as an auto dialer. The scenario is the dialer when running and someone answers, an audio file will be played.

Im running 2 identical ast servers for this, the 1st one occasionally dont play the audio file, while the other one has no problem at all. Usually even if the dialer has not started yet, the audio file is not playing. This issue is very random.

Question is, has anyone else has this same kind of a problem and how to solve this issue.

TIA
