398 HP-UX C SIP Stack Programmer’s Guide
Configuration Parameters
Remarks: Group A parameter
Note The SIP Stack can accumulate several SIP messages before starting to
process them. These messages are placed in a queue and each message uses a
different buffer.
maxNumOfLocalAddresses
The maximum number of local addresses that the SIP Stack may use
simultaneously. Since the application can add and remove local addresses at
runtime, the SIP Stack must know the maximum number of concurrently used
addresses on initialization.
Default value: –1
Remarks: Group B parameter: maxNumOfLocalAddresses = 1 +
numOfExtraUdpAddresses + 1 + numOfExtraTcpAddresses +
bDLAEnabled
Indicates whether or not the DLA feature is enabled. The DLA (Dynamic Local
Addresses) feature enables the application to add and remove local addresses at
runtime. If the feature is enabled the local address list is protected by a lock.
Default value: RV_FALSE
Remarks: Group A parameter
numOfReadBuffers
The number of buffers that will be allocated for receiving SIP messages. When
the SIP Stack works with several processing threads, several incoming messages
can be processed concurrently. To enable this, the SIP Stack should allocate
several read buffers.
Default value: –1
Remarks:
 Group B parameter: numOfReadBuffers =
processingQueueSize/2
