Voice Notes on LinkedIn
Voice notes are not regular attachments, but they work in Primebox LinkedIn conversations. A voice note a lead sends you appears in the thread as a Voice message player with a play button and a download button. You can also reply with a voice note using Send voice note in the reply box, either by recording one, uploading an audio file of up to 1:00 minute, or generating one with AI. See LinkedIn Voice Notes in Salesforge for the full steps.
