Summary:                    setting voicemail greeting when using IMAP backend
causes zero byte messages to be left
Description: 
If you are using an imap server for storage, a zero-byte message is left on
the IMAP server every time you set a voicemail greeting. I created these by
dialing into the voicemail manager, and going to the prompt recording: 
- option 0, 
- option 1, 
- record a prompt, # 
- accept 1, 
check your email for a new zero-byte wav file.

The following error message will also appear on the console:
[Nov 23 12:06:28] WARNING[6032]: app_voicemail.c:1632 base_encode: Failed
to open file:
/var/spool/asterisk/voicemail/default/8080/unavail/msg-001.WAV: No such
file or directory

These zero byte wav files also cause the voicemail manager to hangup when
it comes across one, making them impossible to delete from the voicemail
manager 

You will see the following message on the console whwen you attempt to
remove it:
[Nov 23 12:04:25] WARNING[6029]: format_wav_gsm.c:109 check_header: Read
failed (type)
