   Ah. There was a change to voicemail in 0.8.14. Unfortunetly I don't 
remember
what it is. Search on the iptel archives for voicemail during the past two
months. The articles should be there.

   I kinda remember the include file is named differently. I think it is 
called
voicemail.so instead of vm.so. Sorry but I cannot remember the rest of the
changes. I am still using 0.8.12 while I wait for a new server. I'll run 
0.8.14
when I get that machine.
