If set to "Yes to All SIP", all outgoing SIP messages including
REGISTER message will attach MAC address to the User-Agent
header.
SIP Transport
Determines which network protocol will be used to transport the SIP
message. It can be selected from TCP/UDP/TLS. Default setting is "UDP".
Local SIP Port
Determines the local SIP port used to listen and transmit. The default
setting is 5060 for Account 1, 5062 for Account 2. The valid range is from
5 to 65535.
SIP URI Scheme When
Using TLS
Defines which SIP header, "sip" or "sips", will be used if TLS is selected
for SIP Transport. The default setting is "sip".
Use Actual Ephemeral
Port in Contact with
TCP/TLS
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".
Support SIP Instance ID
Determines if the device 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 isip.instance tag. Default is "Yes".
SIP T1 Timeout
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.
SIP T2 Interval
Specifies the maximum retransmit time of any SIP request messages
(excluding the SIP INVITE message). The re-transmitting and doubling of
T1 continues until it reaches the T2 value. The default setting is 4 sec.
SIP Timer D Interval
Defines the amount of time that the server transaction can remain when
unreliable response (3xx-6xx) received. The valid value is 0-64 seconds.
The default value is 0.
Remove OBP from
Route
Configures the device to remove the outbound proxy URI from the Route
header. This is used for the SIP Extension to notify the SIP server that the
device is behind a NAT/Firewall. If it is set to “Yes”, it will remove the Route
header from SIP requests. The default setting is "No".
Enable 100rel
Actives PRACK (Provisional Acknowledgment) method. PRACK improves
the network reliability by adding an acknowledgement system to the
provisional Responses (1xx). It is set to “Yes”, the device will response to
the 1xx response from the remote party. Default is "No".
