server to unbind the connection. The default setting is "No".
Specifies the frequency (in minutes) that the phone refreshes its registration
with the specified registrar. The default value is 60 minutes. The maximum
value is 64800 minutes (about 45 days).
Specifies the frequency (in seconds) that the phone sends re-registration
request before the current registration expires. The default value is 0.
Defines the local SIP port used to listen and transmit. The default value is
5060 for Account 1, 5062 for Account 2, 5064 for Account 3, 5066 for
Account 4, 5068 for Account 5, 5070 for Account 6. The valid range is from
1 to 65535.
Specifies the interval to retry registration if the process is failed. The valid
range is 1 to 3600. The default value is 20 seconds.
SIP T1 Timeout is an estimate of the round trip time of transactions between
a client and server. If no response is received the timeout is increased, and
request re-transmit retries would continue until a maximum amount of time
define by T2. The default setting is 0.5 seconds.
SIP T2 Timeout is the maximum retransmit time of any SIP request
messages (excluding the INVITE message). The re-transmitting and
doubling of T1 continues until it reaches the T2 value. The default setting is
4 seconds.
Determines the network protocol used for the SIP transport. Users can
choose from TCP, UDP and TLS. The default setting is "UDP".
Specifies if "sip" or "sips" will be used when TLS/TCP is selected for SIP
Transport. The default setting is "sips".
This option is used to control the port information in the Via header and
Contact header. 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".
Configures to remove outbound proxy from route. This is used for the SIP
Extension to notify the SIP server that the device is behind a NAT/Firewall.
The default setting is "No".
Defines whether SIP Instance ID is supported or not. The default setting is
"Yes".
When set to "Yes", a SUBSCRIBE for Message Waiting Indication will be
sent periodically. The phone supports synchronized and non-synchronized
MWI. The default setting is "No".
