402 HP-UX C SIP Stack Programmer’s Guide
Configuration Parameters
Remarks: Group A parameter
connectionCapacityPercent
Determines the recommended percentage of opened connections that the SIP
Stack is allowed to hold at any given moment from its pool of connections.
RFC 3261 recommends that connections are kept open for some period of time
after the last message was exchanged over the connection. However, the exact
time period to leave the connection open is implementation-defined. Using the
connectionCapacityPercent configuration parameter the SIP Stack allows the
application to leave client connections open even after the connections are no
longer in use. When the connectionCapacityPercent parameter is greater than 0,
the SIP Stack will not close connections that are no longer in use. Such
connections will be kept in a separate list and will remain open as long as their
resources are not required. Once the percentage of opened connections exceeds
the allowed connectionCapacityPercent, the SIP Stack will start closing the
connections from this list each time it is required to open a new connection.
Default value: 0.
Remarks: Group A parameter
TCP C
ONFIGURATION numOfExtraTcpAddresses
The size of the localTcpAddresses and localTcpPorts arrays. Applications that
wish to listen to more than one TCP address must allocate the
localTcpAddresses and the localTcpPorts arrays and set the extra addresses in
them. The numOfExtraTcpAddresses parameter indicates the size of each array.
Default value: 0 (no extra addresses)
Remarks: Group A parameter
localTcpAddresses
localTcpPorts
Additional local TCP to which the SIP Stack listens. The extra addresses will be
used in multihomed host applications.
Default value: NULL (no extra addresses)
Remarks:
 Group A parameter
 The addresses and ports array must be allocated according to the
size given in numOfExtraTcpAddresses.
