Abstract
A Unified Messaging (UM) gateway device located at a branch office of a UM system manages calls if the network connecting the branch office to a UM server of the UM system is unavailable. The UM gateway device contains relatively simple hardware and software as compared to the hardware and software of a UM server. The UM gateway device provides call answering functionality, in the absence of the UM server. In various configurations, the UM gateway device provides access to mailboxes, manages incoming calls, provides an outgoing message (e.g., an announcement or prompt), provides an indication where the called-for person can be reached, and, when the network becomes available, returns management of incoming calls to the UM server and/or handles incoming calls in conjunction with the Unified Messaging server.
