It seems to me that the uncompressed file has it right here - if I playback
the
uncompressed file from winamp it is just a little low, but in the ballpark.
If I do the same for the compressed files it is very low.  I would think
the goal would be for the volume in all of the files to be playable without
cranking up the volume.

But something about all of this seems a little odd to me since I'm new
to Asterisk and I would assume if this is the cause that it would have
been brought up and solved a long time ago.

So I ask again - when live conversation is generally at a decent volume
is it common for voicemail recorded messages to be low(er) volume?  When
other users have Asterisk email the recording do they generally have to
raise the volume controls on their computers to hear it?

Thanks
Steve
