Hi! I told you never to call me at this number. But since you did, I left the knife on your back porch…Check to see I got all the blood off. Don’t forget to leave a message, and we’ll talk about the…plan.
10.) Buongiorno, e benvenuti alla John Doe. Per motivi tecnici, non possiamo rispondere personalmente alla vostra chiamata. Ringraziamo per la vostra comprensione. Stiamo lavorando sodo per trovare una soluzione. Se volete, potete lasciare un messaggio sulla nostra homepage: www.johndoe.de – Grazie e arrivederci.

In my (US-based) experience, doctor offices & the like have a place where you can fill out if they can leave messages or not (and some even have asked detailed messages vs callback messages), so that's my perspective! And that I can set different things for different numbers. So my cell phone they can leave detailed messages on any matter, my mother's house phone is detailed from billing only and otherwise callback, her cell phone is callback only. (And they also aren't allowed to tell her anything other than billing, so even if she does call them back about anything else! That was just a measure set up when I lived with her one summer & had no cell reception at her house.)
While missed calls aren’t ideal, you can let your caller know you’re still there for them by having a great voicemail greeting. The best business voicemail greetings let your customers (and potential customers) know why you’re not available and how they can best get in contact with your business. They are also short and to the point. You usually want to keep your greeting between 6 and 24 seconds long so callers don’t hang up halfway through.
