I have an Asterisk server. When some one calls to the server, it just plays back a voice file, like this:
Playback(/usr/en_welcome_notice)
It had worked well for a long time before last night.
I did not do any changes in the Asterisk server and dialplan files, but last night when I called to the server, I heard no sound.
This is the log I extracted from /var/log/asterisk/full for the call:

After trying to find on the internet but found nothing, I tried to restart the server then it worked correctly.
Anyone who knows about this, please give me some explanations!
