A topic is associated with a temporary communications address such as a temporary telephone number. This assignment may be effected by the user when the temporary address is obtained by the user. Illustratively, a user who simultaneously uses a plurality of temporary addresses associates a different topic with each of those addresses. When a caller calls the temporary address, the call is redirected to the user's real address and the user receives the topic that is associated with that temporary address, and preferably also the called temporary address itself, along with the redirected call, and this information is either displayed or announced to the user. The information provides context for the call to the user, and may optionally be captured in call logs. Illustratively, when the user initiates a call via the temporary address or the topic, the temporary address or the topic is provided to the called party as the caller ID information. The user's identity is thus kept secret. The user may select the calling topic or temporary address from a display of the call logs of past calls that involved the topics and temporary addresses associated with the user's real address.
