Abstract: A ring-back tone generator system receives an inbound call connection request forwarded from a phone switch (such as an MSC) that receives the inbound call connection request from a caller phone attempting to connect to a target phone (e.g., a subscriber). The ring-back tone generator system initiates generation of a first call connection on which to provide the customized ring-back tone (and/or custom video image data) to the caller phone. The ring-back tone generator system also transmits, based on receiving the inbound call connection request, an outbound call connection request to the phone switch (such as the MSC) to establish a second call connection through the phone switch to the target phone. Consequently, an MSC that normally handles such call processing now relies on the ring-back tone generator system to handle call processing and provide a custom ring-back tone service.

Abstract: Request information received by a call handler system specifies multiple acceptable call connection encoding options or formats for communicating with a caller. The call handler system forwards the multiple acceptable call connection encoding options to a called destination. The called destination responds with a selection of a first call connection option from the multiple call connection options. The call handler system selects a second call connection option for providing a ring-back tone to the caller while waiting for the called destination to answer his phone. During the wait, the call handler system provides a ring-back tone to the caller via the second call connection encoding option. Upon detection of the called destination answering his phone, the call handler system discontinues playback of the ring-back tone and notifies the caller to communicate with the called destination via the first call connection encoding option as selected by the called destination.

Abstract: A ring-back tone generator system provides a customized ring-back tone to a calling party (attempting to reach a called party) while the ring-back tone generator system participates in alerting the called party of the call connection request. Upon acceptance of the call connection by the called party answering his phone, the ring-back tone generator system can temporarily bridge the caller party with the called party. After at least temporarily providing the bridge, the ring-back tone generator system communicates with a remote phone switch system for purposes of offloading the bridge to a remote device that instead provides the bridge between the caller and the called party. Accordingly, the ring-back tone generator system can participate in a process of providing a customized ring-back tone to a caller, initiate alerting of a called party of the call, bridging a call, and a handing off a call.
