Remarks

Office Communications Server 2007 R2 provides the infrastructure to enable client applications to publish and subscribe to extended, or "enhanced," presence information. The enhanced presence infrastructure includes categories and containers. Categories are individual pieces of presence information, such as status, location, or calendar state. Containers are logical buckets into which clients publish instances of various categories of presence information.

Example Code

publication = QueryCategory("sip:someone@example.com", 1, "userStatus", 0);

Example Code

publication = QueryCategory("someone@example.com", 1, "userCalendarState", 0, false);

Example Code

publication = QueryCategory("+14255551234", 1, "userLocation", 0, true);
