A network device may include a memory to store an aggregate database. The aggregate database may store aggregate voicemail message information, the aggregate voicemail message information including voicemail message information associated with a first device number and voicemail message information associated with a second device number. The network device may include a receiver to receive, over a network, updated voicemail message information associated with the first device number and stored in a first database different from the aggregate database, and to receive, over the network, updated voicemail message information associated with the second device number and stored in a second database different from the first database and the aggregate database. The network device may include a processor to update the aggregate voicemail message information stored in the aggregate database based on the received updated voicemail message information associated with the first device number and based on the received updated voicemail message information associated with the second device number. The network device may include a transmitter to send the updated aggregate voicemail message information to a user device associated with the first device number.
