I need voicemail attachments in mp3 format. I have searched here and google. I see scripts and cookbook instructions for earlier freepbx versions. It seems there is some builtin mp3 module related to moh. I have looked at freepbx gui for voicemail setup, advanced settings, etc. What if anything is included with the freepbx distro to assist with sending the voicmail attachments in .mp3 format? How is it done?
