The use of the PRACK (Provisional Acknowledgment) method enables reliability
to SIP provisional responses (1xx series). This is very important in order to
support PSTN internetworking. To invoke a reliable provisional response, the
100rel tag is appended to the value of the required header of the 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.
Default setting is "Auto".
This option is used to configure default ringtone. If set to "Yes", configured
default ringtone will be played even if Alert-info header is present.
The default setting is "No"
Controls whether the Privacy header will present in the SIP INVITE message or
not, whether the header contains the caller info. When set to "Default", the
Privacy Header will show in INVITE only when "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. Default setting is "Default".
Controls whether the P-Preferred-Identity Header will present in the SIP INVITE
message or not. The default setting is "default": The P-Preferred-Identity Header
will show in INVITE unless "Huawei IMS" special feature is on. If set to "Yes",
the P-Preferred-Identity Header will always show in INVITE. If set to "No", the
P-Preferred-Identity Header will not show in INVITE.
Enables/disables the use of P-Access-Network-Info header in SIP request.
When disabled, the SIP message sent from the phone will not include the
selected header. Default setting is "No".
Enables/disables the use of P-Emergency-Info header in SIP request. When
disabled, the SIP message sent from the phone will not include the selected
header. Default setting is "No".
If Yes, the sip message for register or unregister will contains MAC address in
the header.
For Shared Call Appearance, phone must send a SUBSCRIBE-request for the
line-seize event package whenever a user attempts to take the shared line off
hook. "Line Seize Timeout" is the line-seize event expiration timer. The default
value is 15 seconds. The valid range is from 15 to 60.
