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.
