Abstract: A method for routing a call to a called party who may be located at any one of plural sites which avoids delays in connecting the called party to the received call. When a call is received at a switch, a controller at the switch uses an embedded data base to identify plural sites where the called party may be located from among a multiplicity of sites to which the switch can be connected and causes the switch to initiate parallel connections from the switch to the identified sites. The received telephone call is routed through the switch to a one of the sites at which the called party responds to the initiated connections, and the initiated connections from the switch to the other of the identified plural sites are thereafter disestablished.
