Correct. It's bordering on illegal to lie about your callerID (not
quite though, because it's not legislated). Certainly you're not going
to be able to do it on any basic commercial service. Carrier
interconnects can do it obviously.

The reason is related to emergency services (amongst other things), a
1300 number has no physical location. Origination numbers can be
geographic or mobile but must be associated with a specific location or
device. Technically, if you have a 100 number range that you split over
multiple locations, you're required to indicate which numbers are
where. Doesn't happen often though.

It even goes so far as if you're transiting a call you must preserve
the originating number. This means if you setup a calling card platform
as a carrier you may have a few extra requirements.

So I've heard, can't quite understand the benefits, but this is the way
things are.
