Hi, we would love to at least listen to them via the Missive app.

Ara Bozadjian thanks for the update. Are you guys going to debug the error? There must be a solution as Zendesk allows receiving and sending voice notes easily. TY

Joe Lapscher We've been testing this, looks like you can RECEIVE Voice notes, they come as .ogg attachments which can be played in a browser. Trying to send an audio recording (as a VN effectively), we recorded audio from laptop using QuickTime, saved as .mp4, then changed to .ogg - that file attaches but when you try and send you get this error: https://www.twilio.com/docs/api/errors/63019
