[asterisk-users] Blank Voicemails

[Dave Bour]

Before filing a bug report, I'd recommend you upgrade the machine as the
digum crew is sure to say it too.   I remember a while back similar
"bad" wav files though way too intermittent to find a cause, though I
don't remember exactly what release, when exactly nor have I seen it in
several months.
