Voicemail Directory app with ODBC storage

I am using Asterisk realtime static to replace the voicemail.conf file. I am also using ODBC storage for the voicemail messages. All works perfectly except that when the directory app is launched by 411 in my dialplan. and after a three digit key press is entered representing the last name, Asterisk spells the name found, rather than playing the recorded name. This would be normal operation should the greeting not be there, but it is.
Any ideas?

Sounds like a bug, you should probably submit it.
