Abstract: A computer-implemented method for communication includes assigning to at least first and second communication terminals (22) of a communication system (20) at least respective first and second private identities and a common public identity different from at least the first and second private identities. Registrations of the public identity and of at least the first and second private identities are simultaneously maintained in the communication system (20). A request is received to set up a call in which the public identity serves as one of a source and a destination of the call. The call is established between a third communication terminal and one of at least the first and second communication terminals (22) using the simultaneously-maintained registrations.
