Typically, voicemail drop requires sales representatives to call the prospect first. It leaves the prerecorded voicemail message only if it detects an answering machine instead of a live customer. However, a ringless voicemail drop (RVM) sidesteps this requirement and directly drops the voicemail into the voicemail box without calling the phone and ringing the line.RVM or direct-to-voicemail software makes it possible by using adaptive signaling technology. It connects to the voicemail servers of the service provider and then sends the message to the voicemail inbox. Since the message is stored on the server space associated with the number and not on the phone, the recipient doesn’t receive any missed call notifications.
