Abstract: A node in a telephone network such as a switch stores associations between called and calling parties and colored ringback media played by the called party. Later, when the same calling party calls the called party, the node retrieves the stored ringback media and forwards the media to the calling party on behalf of the called party. In one embodiment, the node comprises a switch. In other embodiments, the node is a central server caching called/calling party combinations and associated ringback media and provides the ringback media forwarding function for a distributed population of called parties. Such called parties may comprise wireless phones.

Abstract: A media system includes a content platform that provides an interface for browsing and/or purchase of ringback media content by a user of a communications device. The system includes a profiles database containing profile information for a multitude of users of communications devices. The media system further includes a memory storing instructions for execution by the platform which causes it to 1) obtain information from the device including assignment of ringback media content to contacts in an address book maintained on the device; and 2) update the profiles database in accordance with the information obtained from the device. The information obtained in 1) may be obtained automatically, each time the user accesses the content platform. The system may further include an analyzer module which is used to generate targeted promotional messages based on the contents of the profile database.

Abstract: A method and system for registering a client for a call-pickup service and for executing the call-pickup service for a new call placed to a given communication device. The call-pickup service may carried out, in part, by providing the client with notification of when the new call is placed to the given communication device, the client requesting that the new call be re-routed to a location other than the given communication device, and a server re-routing the new call to the location other than the given communication device. The location other than the given communication device may be the client that registers for the call-pickup service or another location.

Abstract: Methods and systems for facilitating distribution of ringback files to caller devices are provided. A ringback file server may receive a request to associate a ringback file with a callee device and a caller device. Responsively, the ringback file server transmits a copy of the ringback file to the caller device, thus enabling the caller device to play out the ringback file when the caller device subsequently initiates a call to the callee device. Preferably, the ringback file is a high quality audio or video file. Thus, locally storing the ringback file at the caller device facilitates playout of high quality ringback media and also avoids requiring that the ringback file server stream ringback media in-band to the caller device.

Abstract: Disclosed are methods and systems for providing pre-call-connection messaging services to calling parties. In at least one embodiment, a first call-setup request is received from a calling party, reflecting a request that an active call be set up between the calling party and a called party. Responsive to the first call-setup request, at least one network device starts to attempt to establish the active call between the calling and called parties at least in part by transmitting a second call-setup request to the called party. Prior to receiving a response to the second call-setup request, the at least one network device starts to record a message for the called party while continuing to attempt to establish the call. If the active call is not successfully established prior to an affirmative termination of the message recording, the recorded message is thereafter made accessible to the called party.
