ABSTRACT:
A technique for supplying alternative contact information when a communication attempt is unsuccessful is described. The technique comprises receiving an inquiry that includes an indication of an unsuccessful communication attempt and an identifier or address for the target of the failed communication attempt. Next, it is determined whether the identifier or address is associated with a group. If so, a response is generated, the response including one or more other identifiers or addresses associated with the group. Finally, the generated response is transferred in response to the inquiry.
