Use the Session Initiation
Protocol (SIP) application router
to select the order in which SIP applications are triggered. When
configuring a SIP application router, you can either use the default
application router or create a custom application router.
About this task
The SIP container
provides an application router component
called the Default Application Router (DAR). The DAR component uses
a configuration text file, similar to a Java properties
file, that defines the order in which the application router sends
SIP requests to applications.
Restriction: WebSphere® Application Server
has a default way of sorting the order of SIP applications invocation
using the Startup behavior settings. The sorting order is based on
the application weight. This weighting policy only applies if you
do not specify a DAR configuration file, or if a custom application
router has not been associated with the server or cluster.
You
can either use the DAR or a custom application router to perform application
routing, as described in the procedure.
Use the following procedure
to select the best method to implement the SIP application router
for your configuration.
