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.

I am also experiencing this bug (1.4 SVN 89397  18-Nov-2007).  I can
provide a defective message if someone is having problems debugging this. 
I suspect that the problem isn't with the .wav file, but rather with the
.gsm file.  I believe that ast_control_streamfile() is returning something
<0 because of the file either being too short or missing some required
header.  I'll go ahead and see if I can help locate the trouble as well.

You can create the zero length message file by interrupting the voicemail
OGM with "#" and then hanging up very quickly.  It takes a few tries, but
you can eventually do it.
