Why nobody leaves a voicemail any more
Leaving a message is a commitment. It asks the caller to wait, to be available when you ring back, and to trust that you will. Most people ringing a business for the first time will not make that commitment.

Voicemail depended on scarcity. When a business had one phone number and finding an alternative meant a directory, leaving a message was rational, because trying somebody else was expensive.
Search removed the scarcity. There are now eight alternatives on the screen the caller is already holding, and the cost of trying the next one is a thumb movement.
The commitment problem
A voicemail is a promise to be interruptible later. The caller has to say who they are, explain their problem to a machine, and then remain available for a call back at a time they do not control.
For an existing customer that is a fair trade. For somebody who has never dealt with you, it is a lot to ask in exchange for nothing, from a business that has just demonstrated it does not answer its phone.
Why your voicemail box misleads you
The people who leave messages are overwhelmingly people who already know you: existing customers, suppliers, colleagues. They have a reason to persist.
New enquiries, which is the money, are the group least likely to leave one. So the contents of your voicemail box systematically understate what you are losing and make the problem look smaller than it is.

Callwise answers your phone the way this article describes. Ring it, ask it something awkward, and see whether it holds up.

The more urgent the need, the less likely a message. Nobody standing outside their locked house, watching water come through a ceiling or trying to get a car started before a shift leaves a voicemail and waits.
These callers are also the least price sensitive people who will ring you all week. Voicemail filters your enquiries in precisely the wrong direction.
The five minute rule
When somebody does leave a message, speed is everything. Returned within a few minutes and the conversation usually continues as if the call had connected. Returned the next morning and a meaningful share have already booked elsewhere.
This is why call back systems tend to disappoint. They are competing against a competitor who simply answered.
What actually works
Being answered. There is no clever version of this. The alternatives to answering all involve asking the caller to do extra work at the exact moment they are least willing to.
If you cannot answer, keep the greeting under ten seconds, say precisely when you will ring back, and keep that promise. It will not recover most of them, but it recovers more than a thirty second greeting that lists your opening hours.
Questions people ask
Would a text back service help?
It helps more than voicemail, because it reopens the conversation on a channel people actually use. It still loses to answering, because the caller is comparing you with a competitor who picked up.
How many callers leave a message?
It varies enormously by trade and by how well the caller knows you. The reliable pattern is that first time callers leave far fewer messages than existing customers, so your own voicemail volume is not a guide to how many new enquiries you lost.

Voicemail is not a safety net
Voicemail was designed for a world where people had no alternative. They have alternatives now, and the alternative is the next result on Google.
What a missed call actually costs
A missed call leaves no trace anywhere in your business. No enquiry, no note, no record. Which is exactly why it is the easiest loss to ignore and the most expensive to keep making.
When your customers actually ring
Most businesses staff the phone for the hours they work. A significant share of enquiries arrive in the hours they do not.
