Event:Refer to the transferor for any 1xx response returned by
the transfer target, on the transfer call leg.
If set to no, the phone will only send a NOTIFY for final
responses (200 and higher).

This parameter applies only if <SIP Remote-Party-ID> is set to
yes; otherwise, it is ignored.

his caller-id. If the parameter is set to no, the FROM header's
display-name and user-id are not masked. The Remote-Party-
ID header indicates privacy=full when the caller wishes to
block his caller-id.
Default: yes.
