initial signaling messages.
When set to "Auto", the phone will look for the caller ID in the order of
P-Asserted Identity Header, Remote-Party-ID Header and From Header in the
incoming SIP INVITE. When set to "Disabled", all incoming calls are displayed
with "Unavailable". When set to "From Header", the phone will display the
caller ID based on the From Header in the incoming SIP INVITE. The default
setting is "Auto".
Controls whether the Privacy Header will present in the SIP INVITE message
or not. The default setting is "default": the Privacy Header will show in INVITE
unless "Huawei IMS" special feature is on.
If set to "Yes", the Privacy Header will always show in INVITE. If set to "No",
the Privacy Header will not show in INVITE.
