Ben,

You can set calling name on the device or trunk level. Most landlines and
businesses not using SIP will only receive the calling number, the name is
looked up through the cnam database. You can query the cnam database here:
https://www.opencnam.com. The cnam database should be updated to reflect
your business name, I recommend spot checking your DIDs to see what is
displayed in cnam. I have access to some different sip carriers if you want
to do some testing, send me a direct email and I can tell you exactly what
we are receiving for your calls.
