Description
When enabled, authorization is required for initial
incoming INVITE requests from the SIP proxy.
If set to yes, as a transferee, the phone will send a
NOTIFY with 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).
NOTE
Not applicable to the WIP310.
This parameter applies only if <SIP Remote-Party-ID>
is set to yes; otherwise, it is ignored.
If the parameter is set to yes, the FROM header's
display-name and user-id fields are set to anonymous
when the caller blocks 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.
