Disclosed are methods and systems to authenticate a UE to grant the UE access to a voicemail account. A network entity and a UE may exchange a secure key that may then be used to authenticate the UE with the voicemail server. The exchange of the secure key may be triggered in response to receiving a user request to access a voicemail account at a voicemail server. The UE may then include the received secure key in an origination request seeking to set up a call to the voicemail server, and the voicemail server may authenticate the UE by comparing the secure key received in the origination request with the secure key most recently transmitted to the UE. If the received secure key is the same as the most recently transmitted secure key, the UE is authenticated.

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.
