This update was released on April 7th, 2009:
ooma Voicemail Forwarding
There were two improvements released for the ooma Voicemail forwarding feature:
1. Previously voicemails were forwarded as attachments within a forwarded message. This caused a message reading error on email clients when retrieved from certain email servers.
2. Voicemails are now forwarded as MP3 attachments instead of WAV files, greatly reducing the file size of the message.
