Abstract: A method of creating an application-based subnet for enhanced telephony call processing includes the steps of determining during the processing of a call that the call may require additional call processing services available at a second node located within an application-specific subnet, and transferring the call and call control to the application-specific subnet for further call processing.

Abstract: A networked system of voice-activated dialers is described. When a calling party using a local voice-activated dialer utters a phrase which indicates that information to reach a called party may be available at a remote site, a network connection is established to the remote site, spoken words or phrases are transmitted to the remote site, and the called party information is obtained from the remote site. The called party information is used to provide additional networked services to the calling party such as call-completion, voice messaging, or paging. These additional networked services may use the Public Switched Telephone Network (PSTN) and an existing signaling network such as the Signaling System No. 7 network.
