It's the "CNAM" field.

In the United States, the CNAM is populated using a database dip into
SS7, so setting the name on outbound calls will probably not get you
anywhere on the public PSTN (unless you have a private network, and
your provider has told you that they will honor the CNAM that you
set), because the CNAM is done at the terminating side, not the
originator.  However, I believe that over in Canada, you can set CNAM
on the outbound PRI and the PSTN will carry that through the network.

Outside of NANPA, I've found that caller name doesn't work.
