Caller ID Question ....

iPhone 4
Version 6.0.1
AT&T
.................

I do phone volunteer work for several national charitable organizations.

I'd like to use my iPhone to make those calls - but wish to remain anonymous to those I'm calling.

Does my iPhone automatically identify me when making outgoing calls?

Settings > General > About > Name: Steve Smith
Will Steve Smith automatically show up on the recipients caller ID ?

Thanks
