I have managed to get Voicemail working. I can leave messages, call into mailboxes to access messages, delete messages, etc.
However I wanted to receive email notifications with audio attachments. My voicemail.conf looks like this:
emaildateformat=%A, %B %d, %Y at %r
pagerdateformat=%A, %B %d, %Y at %r
sendvoicemail=yes ; Allow the user to compose and send a voicemail while inside
Is there something else I need to do? Thanks for your time
