HP-UX C SIP Stack Programmer's Guide (Novembery 2007)

Configuration 409
Configuration Parameters
processingTaskStackSize
This parameter is relevant only for RTOS when the SIP Stack is executed in
multithreaded mode. It defines the Stack size used by the processing tasks. The
size is given in bytes.
Default value: 30000
Remarks: Group A parameter
ADVANCED FEATURES A number of the SIP Stack advanced features require the following special
configuration parameters.
A
DVANCED BEHAVIOR
C
ONTROL
bOldInviteHandling
Until version 4.0, the implementation of an Invite transaction that received a
2xx response was not according to RFC 3261, but according to bis 2543.
According to RFC 3261, an Invite and its 2xx are a full transaction and the
ACK on 2xx should be a new transaction. In previous SIP Stack versions, ACK
was considered to be part of the Invite transaction. From this version on, an
ACK is no longer part of the Invite transaction. The Invite transaction will be
terminated when 2xx is received or sent. In order to keep the non-standard SIP
Stack behavior, you should set the bOldInviteHandling parameter to RV_TRUE.
Default value: RV_FALSE
Remarks: Group A parameter
manualAckOn2xx
Specifies whether the ACK on a 2xx response is performed manually by the
application (RV_TRUE) or automatically by the call-leg (RV_FALSE).
Default value: RV_FALSE—the ACK is sent automatically.
Remarks: Group A parameter
manualBehavior
Enables the application to handle events that the SIP Stack otherwise handles
automatically. The manualBehavior parameter relates to the following events:
 Sending a final response to the INVITE transaction after
receiving a CANCEL to the invite. (The CANCEL is still
accepted automatically.)
