IBM® WebSphere® Presence
Server Component provides
ways in which users can gain access to a rich supply of data from
external sources, such as S-CSCF and external communities.
Presence Server provides
a sample application to demonstrate the behavior of a SIP external
source. You can modify the sample application to interact with external
sources in your own enterprise.
The sample application is a SIPp script and performs the following
functions:
- Accepts incoming subscribe requests, responding with a 200 OK
response and a NOTIFY message that contains a simple presence document.
The document includes the identity of the subscribed presentity.
- Simulates state changes for the subscribed presentity by periodically
sending NOTIFY messages with changes in the presence information (for
example, a basic status change).
- Stops sending NOTIFY messages when it receives an unsubscribe
request from Presence Server.
The sample application is found in the Telecom Application Enablement Feature in
the Samples Gallery.
Note: SIPp is a free, open-source test tool with which you can create
applications that generate SIP traffic. For more information about
SIPp, refer to the
SIPp Web site (http://sipp.sourceforge.net/).
