Specifies the frequency (in minutes) in which the phone refreshes its
subscription with the specified registrar. The maximum value is 64800 (about
45 days). The default value is 60 minutes.
Specifies the time frequency (in seconds) that the phone sends re-
registration request before the Register Expiration. The default value is 0.
Enable OPTIONS Keep Alive to check SIP Server.
Default is "Yes".
Time interval for OPTIONS Keep Alive feature in seconds.
Default is "30" seconds.
Number of max lost packets for OPTIONS Keep Alive feature before the
phone re-registration. Default is "3".
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. Default 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".
Determines whether or not to listen to multiple SIP protocols.
Transport Only: will listen to configured transport protocol only.
Dual: will listen to TCP when UDP is selected.
Dual (Secured): will listen to TLS/TCP when UDP is selected. If TCP or
TLS/TCP is selected, UDP will be listened to
Dual (BLF Enforced): will try to enforce BLF subscriptions to use TCP
protocol by adding 'transport=tcp' to the Contact header.
The default setting is "Transport Only".
Specifies if "sip" or "sips" will be used when TLS/TCP is selected for SIP
Transport. The default setting is "sips".
