Abstract
The present invention relates to providing presence information bearing on the availability of a first user involved with a call to a second user involved with the call. In general, call information bearing on the call is received and triggers a request for presence information associated with the first user. Upon retrieval of the presence information associated with the first user, the presence information is effectively delivered to the second user in a manner informing the second user of the availability of the first user to receive a call. Thus, when an attempt to establish a call between the first and second users has failed, the second user may monitor the presence information relating to the availability of the first user to decide when, and perhaps how, to contact the first user.
