My carrier already offers a premium voicemail — isn't that enough?

Premium voicemail records better, but it's still voicemail: the caller talks to a beep, doesn't know when you'll call back, and their request sleeps until you listen. No qualification, no booked appointment, no urgency sorting — at night, the message waits 12 hours. Signal replies by text in under 10 seconds, qualifies, and offers a slot before the caller dials someone else. Staying honest: premium voicemail is nearly free, and it's the right choice if you get two calls a week.
