## Abstract

A method and system for automatically collecting information relating to calls. A method is described for collecting call information that establishes one or more subscription sessions with one or more endpoint devices. Each of the one or more endpoint devices is associated with an address of record. Then, the method receives a dialog notification in one of the one or more subscription sessions that an endpoint device has received a call from a caller. A call entry is generated that provides call information that is associated with the call and the caller. Thereafter, the call entry is stored in a chronological call history that provides call information that is associated with one or more of calls to the one or more endpoint devices.
