[asterisk-users] Asterisk + Monitor() Poor quality

[Kim Delevati]

Ok, I used Record with wav49 and, instead of recording in a good quality
like Monitor, it was almost as bad as regular wav.

These things crack my head, now I'll have to switch all my Record for
Monitor, somehow limiting time and in a way that # stops the recording.
Should be fun.
