Methods and apparatus for unified communication across circuit-switched and packet-switched network domains. In one embodiment, voice or data available in one domain (e.g., circuit-switched such as a PSTN) can be seamlessly forwarded onto another domain (e.g. packet-switched such as a WLAN). A bridge or intermediary device is used that is coupled to both the circuit-switched network and packet-switched network. This bridge device allows bidirectional operation and permits, for example, a user to receive a telephone call at a user's home network via a PSTN, and forward that telephone call or information related to that call over another network such as a local IP network (e.g. a WLAN) to the user, where the user can answer that call or otherwise receive information associated with the call on their primary user device (e.g., cellular phone).
