Upgrade to 1.8 - voicemail forwarding fails

I’ve been trying to figure this one out…after an upgrade to 1.8 from 1.6, the ability to forward vmails over the phone is lost. The system goes through the menus and gives “your message has been saved” to the caller. This happens with or without prepending.

If you prepend a message, you get the following:

Either way, you get the following with no other information.

I have tried fixing permissions to 777 on the files, adding links as 4590@default in case that was the folder, and different file formats. I have the same problem each time. Asterisk is running as asterisk:asterisk. This happens on both of our Asterisk machines.

Help?
