  • Failover voice messaging
    Patent number: 7912189
    Abstract: An improved approach to failover voice messaging services is provided. In one example, a method includes detecting a network communication interruption between a branch office and a main office, provisioning a mailbox of a failover voice messaging system of the branch office, and receiving an incoming call at the branch office. The method also includes routing the incoming call to the mailbox, storing a message associated with the incoming call in the mailbox, and detecting a restored network connection between the branch office and the main office. The method further includes synchronizing the message between the mailbox of the failover voice messaging system of the branch office and a corresponding mailbox of a voice messaging system of the main office in response to the restored network connection. Failover voice messaging systems supporting such features are also provided.
