HP-UX Java SIP Stack Programmer's Guide (February 2008)

Table 2-1 SIP Stack Parameters (continued)
DescriptionParameter Name
Informs the underlying implementation about
supported extension methods that create new
dialogs. This configuration flag must be used
for dialog creating extension methods; other
extension methods that do not create dialogs
can be used using the method parameter on
request, assuming that the implementation
understands the method. If more than one
method is supported in this property, each
extension must be separated with a colon, for
example FOO:BAR. This property is optional.
javax.sip.EXTENSION_METHODS
Prevents an application from handling
retransmission ACK requests, 1xx, and 2xx
responses for INVITE transactions. Instead,
SipProvider handles the retransmissions. The
RETRANSMISSION_FILTER option is useful
for hiding protocol retransmission semantics
from higher level programming environments.
This property is optional and the default value
is OFF.
javax.sip.RETRANSMISSON_FILTER
Provides the flexibility to toggle the dialog
support. The option to turn off the dialog
support is motivated by dialog free server
(such as proxy servers) that do not want to
pay for the overhead of the dialog layer and
user agents that require to create multiple
dialogs for a single INVITE message. The
default value is ON.
javax.sip.AUTOMATIC_DIALOG_SUPPORT
Specifies a comma-separated list of events that
results in forked SUBSCRIBE dialogs. Each
element in this list must be of the syntax
packagename.eventname. This property is
optional.
javax.sip.FORKABLE_EVENTS
Specifies the router that the stack must consult
for routing decisions. If this property is set to
true, the application installed router is
consulted for all routing decisions (that is, both
dialog SIP and non-SIP request URIs). If this
property is set to false, the user installed router
is consulted for routing of non-SIP URIs. This
property is optional. The default value for this
property is true.
