It's challenging enough to attempt to address each business call that comes in over the course of a day. Traditionally, voicemail messages have listened to only when time is available and even then, you would go through each message one at a moment while concentrating on the computer, ignoring mailings or low-priority calls to get to the relevant voicemails from prospective new clients or faithful current customers. By the time you've processed certain texts and initiated the preference callbacks, you might have missed a client.
