Techniques for using call history for voice data over a packet-switched network includes receiving call history data that indicates a redirected network identity that served as a target of a particular voice data session from a particular calling party. The redirected network identity is different from both a caller network identity that identifies the particular calling party, and a current target network identity that identifies a current target party of the particular voice data session. A call history display composition is formed that indicates at least that the redirected network identity exists. The call history display composition is presented for viewing by at least one of the particular calling party and the current target party. These technique allow a party to redirected communications to easily call or save the network address of a former target of the call.
