[Asterisk-Users] voicemail issue with beta1 & beta2

[niles at atheos.net]

I'm having a voicemail problem that I can't seem to eradicate, and  
I'm hoping to get some direction from this list.
The phone system in question is using 1.2 Beta 2, using Realtime with  
about 5k users in the database.
There have been a few messages that appeared to be blank, but when  
they forwarded to another extension with a
prepended message, the original message would appear.  Apparently  
some voicemail messages have an empty msgXXXX,txt
file, which the voicemail system recognizes as a voicemail, but the  
corresponding msgXXXX.wav file won't play.  When the user
forwards what they believe is a blank message to my mailbox, the  
msgXXXX.txt file is rewritten, and I receive the prepended message
followed by the original message.  I didn't see this kind of issue in  
the archives, or in google.
Please advise
Thanks!
