404 HP-UX C SIP Stack Programmer’s Guide
Configuration Parameters
maxTlsSessions
The maximum number of TLS sessions. A TLS session is the TLS equivalent on
a TCP connection and contains TLS data required to manage the TLS
connection. The SIP Stack will be able to handle a maximum of maxTlsSessions
concurrent TLS connections.
Default value: –1
Remarks: Group B parameter: maxTlsSessions = maxConnections (each
opened connection can be used for TLS)
TIMER CONFIGURATION retransmissionT1
T1 determines several timers as defined in RFC3261. For example, When an
unreliable transport protocol is used, a Client Invite transaction retransmits
requests at an interval that starts at T1 seconds and doubles after every
retransmission. A Client General transaction retransmits requests at an interval
that starts at T1 and doubles until it reaches T2.
Default Value: 500
Remarks: Group A parameter.
retransmissionT2
Determines the maximum retransmission interval as defined in RFC 3261. For
example, when an unreliable transport protocol is used, general requests are
retransmitted at an interval which starts at T1 and doubles until it reaches T2. If
a provisional response is received, retransmissions continue but at an interval of
T2.
Default Value: 4000
Remarks: Group A parameter. The parameter value cannot be less than 4000.
retransmissionT4
T4 represents the amount of time the network takes to clear messages between
client and server transactions as defined in RFC 3261. For example, when
working with an unreliable transport protocol, T4 determines the time that a
UAS waits after receiving an ACK message and before terminating the
transaction.
Default Value: 5000
Remarks: Group A parameter
