SIP OPTIONS Keep Alive
Maximum Tries
Configures the maximum times of sending OPTIONS message
consistently from the phone to server. Phone will keep sending OPTIONS
messages until it receives response from SIP server. The default setting is
"3", which means when the phone sends OPTIONS message for 3 times,
and SIP server does not respond this message, the phone will send RE-
REGISTER message to register again. The valid range is 3-10.
Subscribe for MWI
Configures the phone system to subscribe voice message service. If it is
set to "Yes", the phone system will periodically send SIP SUBSCRIBE
message for Message Waiting Indication service. GXV3380 phone system
supports both synchronized and non-synchronized MWI. The default
setting is "No".
Use Privacy Header
Determines if the Privacy header will be presented in the SIP INVITE
message and if it includes the caller info in this header. If it is set to
"Default", the Privacy Header will be omitted in INVITE when "Huawei IMS"

"No", it will always be omitted. The default setting is "Default".
Use P-Preferred-Identity
Header
Specifies if the P-Preferred-Identity Header will be presented in the SIP
INVITE message. If set to “default", the P-Preferred-Identity Header will be
omitted in SIP INVITE message when "Huawei IMS" special feature is
active. If set to "Yes", the P-Preferred-Identity Header will always be
presented. If set to "No", it will be omitted. The default setting is "Default".

address in the header, and all the outgoing SIP message including

unregister message nor the MAC address be attached to the User-
Agent header for any outgoing SIP message.
