Summary:                    [patch] Empty voicemail message file causes call
into voicemail to disconnect
Description: 
After upgrading from 1.4.9 to 1.4.13 we are having the following problem
with voicemail.  We sometimes get voicemail messages left in mailboxes
where the wav / data file is 44 bytes long.  The file basically has a
header but no data.  Under 1.4.13 calls into voicemail will be disconnected
after listening to such a message.  1.4.9 did not have this issue.

In case you are curious, these 44 byte messages are being left despite
minmessage being set to 3 in the general section of voicemail.conf.  These
messages are accompanied by a console message "app.c: No audio available on
SIP/IP ADDRESS-b50d7b38??"

Nothing special in the console / log file.  Looks the same as when a
caller hangs up normally even though in this case they are being
disconnected.

OK - I understand.  This will be a little more difficult to test then, as
the issue which creates the 44 byte wav files only happens on our
production servers under load and is not re-producible in my dev
environment.  I will schedule this patch to be included in our next
software update.  I did try normal voicemail scenarios, and it doesn't seem
to break anything.

Will post back results when I have them.
