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.

dtyoo:  it's not supposed to prevent you getting disconnected; it's
supposed to prevent those empty messages from getting created in the first
place.  You'll need to delete all empty messages that currently exist on
the system.
