Abstract: A method, system and apparatus for applying virtual threads in debugging a business process program. In accordance with the present invention, different activities in a business process can be associated with corresponding virtual thread identifiers where groups of the activities related to one another through corresponding links can be assigned a single virtual thread identifier. Based upon the association of activities with corresponding virtual thread identifiers, a directed graph of different activities of different virtual thread identifiers can be generated. Accordingly, debug operations including applying breakpoints, step over debugging and the like can be applied to a business process program regardless of the host platform for any one activity in the business process program.

Abstract: A method, system and apparatus for name-alias based delivery of services through the public switched telephone network (PSTN). A method for resolving caller identity in a PSTN can include detecting an attempt to establish a telephone call between a calling party and a called party and prompting the calling party from within the PSTN for clarifying information. An alias for the calling party can be resolved based upon the clarifying information. Subsequently, the alias can be forwarded to the called party for use by the called party in identifying the calling party at the time of the telephone call.
