How to get Business name on caller id?

[MSF]

Your number will show when you call someone else. If you are in their Contact List, then your name will also show up on their screen.

Other than that, I'm not really sure how else your name can show up.

There is a way when making a call the business name shows up.  I've seen this happen multiple times, and I do not have that number saved.
I think it's called CNAM, and it can be set up if using VoiP, otherwise I believe this is something that Smarty (the Provider) has to do (whether or not they can, is a different matter).

May or may not be relevant, but SMARTY state online:

"SMARTY is a service that's just for consumers and is only intended for personal use."

Elsewhere, in their terms & conditions there are references to only using their services for 'normal' consumer activities - good luck @Limelord.
