If enabled, the device will add Authorization header in initial REGISTER request.
Enables SIP OPTIONS to track account registration status so the device will send periodic
OPTIONS message to server to track the connection status with the server. The default setting is
"No".
Configures the time interval when the device sends OPTIONS message to SIP server. The default
value is 30 seconds, in order to send an OPTIONS message to the server every 30 seconds.
The default range is 1-64800.
Configures the maximum times of sending OPTIONS message consistently from the device to
server. Device will keep sending OPTIONS messages until it receives response from SIP server.
The default setting is "3", which means when the device sends OPTIONS message for 3 times, and
SIP server does not respond this message, the device will send RE-REGISTER message to register
again. The valid range is 3-10.
When set to "Yes", a SUBSCRIBE for Registration will be sent out periodically.
Controls whether the Privacy header will present in the SIP INVITE message or not, whether the
header contains the caller info:
● If set to "Yes", the Privacy Header will always show in INVITE
● If set to "No", the Privacy Header will not show in INVITE.
Controls whether the P-Preferred-Identity header will present in the SIP INVITE message or not,
whether the header contains the caller info:
● 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
If set to "Yes except REGISTER", all outgoing SIP messages will include the device's MAC
address in the User-Agent header, except for REGISTER and UNREGISTER. If set to "Yes to All
SIP", all outgoing SIP messages will include the device's MAC address in the User-Agent header.
If set to "No", the device's MAC address will not be included in the User-Agent header in any
outgoing SIP messages.

from TCP/UDP/TLS.
Default setting is "UDP".
Configures whether to enable TCP Keep-alive for the TCP connection between the terminal and
the SIP server.
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
device use TCP or TLS. If set to No, these port numbers will use the permanent listening port on
the device. Otherwise, they will use the ephemeral port for the particular connection. The default
setting is "No".

identify the device. If set to "Yes", the SIP Register message Contact header will include
+sip.instance tag. Default is "Yes".
