Architecture that allows a user to control the way a connection is made to a destination is described. A destination can be tagged with an attribute that defines how the connection to that destination should be routed. For example, a phone address book allows the user not only to enter the usual call recipient information such as name and telephone number, but also to add an attribute in the form of a network identifier associated with a network to be used when connecting to the destination. Where multiple networks are associated with the destination, the phone subsystem, recognizing that the destination now has multiple network IDs for connecting the call, can prompt the user to select the desired network pathway. The user can also tag the destination with a protocol that should be employed. Thus, not only will the phone be connected according to the network, but also the protocol.
