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. GXV3370 phone system
supports both synchronized and non-synchronized MWI. The default
setting is "No".
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"
special feature is active. If set to "Yes", it will always be presented. If set to
"No", it will always be omitted. The default setting is "Default".
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".
Determines which network protocol will be used to transport the SIP
message. It can be selected from TCP/UDP/TLS. Default setting is "UDP".
Determines the local SIP port used to listen and transmit. The default
setting is 5060 for Account 1, 5062 for Account 2, 5064 for Account 3, 5066
for Account 4, 5068 for Account 5, and 5070 for Account 6. The valid range
is from 5 to 65535.
Defines which SIP header, "sip" or "sips", will be used if TLS is selected
for SIP Transport. The default setting is "sip".
Determines the port information in the Via header and Contact header of
SIP message when the phone system use TCP or TLS. If set to No, these
port numbers will use the permanent listening port on the phone.
Otherwise, they will use the ephemeral port for the particular connection.
The default setting is "No".
Determines if the phone system will send SIP Instance ID. The SIP
instance ID is used to uniquely identify the device. If set to "Yes", the SIP
Register message Contact header will include +sip.instance tag.
The default setting is "Yes".
Defines an estimate of the round-trip time of transactions between a client
and server. If no response is received in T1, the figure will increase to 2*T1
and then 4*T1. The request re-transmit retries would continue until a
maximum amount of time define by T2.
The default setting is 0.5 sec.
Specifies the maximum retransmit time of any SIP request messages
(excluding the SIP INVITE message). The re-transmitting and doubling of
