Given that you can only send CallerID on a digital circuit, it's going to
depend upon the signalling.  If the prilocaldialplan is set to 'unknown' or
'dynamic', then you send the '1'.  If the prilocaldialplan is set
to 'domestic', then you leave the '1' off (because it's implied).

In terms of SIP or another VoIP protocol, you use whatever your provider
specifies.
