When enabled as a transferee, the phone sends a
NOTIFY with Event:Refer to the transferor for any 1xx
response returned by the transfer target, on the transfer
call leg. To enable this feature, select yes.
If set to no, the phone only sends a NOTIFY for final
responses (200 and higher).

When enabled and the caller blocks his caller-id, the
FROM header display-name and user-id fields are set to
anonymous. This parameter applies only if <SIP Remote-
Party-ID> is set to yes; otherwise, it is ignored.
When disabled, the FROM header display-name and
user-id are not masked. The Remote-Party-ID header
indicates privacy=full when the caller tries to block his
caller-id.
To enable this feature, select yes. Otherwise, select no.
Defaults to yes.
