[Asterisk-Users] Why even have set CallerID option?

[Matthew Boehm]

Why even have the ability to set callerid name/number if end offices don't
honor it?

For example, I have a SIP UA registered and in the sip.conf I have:

    callerid="Mark Mane <2815692712>"

When that phone makes an outbound local call, asterisk will terminate it on
PRI connected to asterisk box to Time Warner.

When the called party looks at their caller id display screen it shows the
number that is in sip.conf, but does not show the name I have set in the
sip.conf; instead it shows our company name (since we "own" the number).

If it is the responsibility of the last end office to do a data-dip and
select out the name, then that means I cannot control the callerid name,
correct?

So I guess that callerid name is only useful for VoIP<->VoIP calls that go
thru asterisk?
