Should not be a permissions problem as both the asterisk and fop2 servers run under the same UID. Did the debug and it is the same as the original log I posted in this thread. I think it's a context problem with the correct context not being passed to the fop2 server and/or asterisk.
Below I try and move (by dragging) a voicemail from the inbox to the Trash area.
