ABSTRACT:
An interface for use in a telephone communication system provides for connection of a telephone switch to an IP network, allowing data signals between the telephone switch and a VMS to be transmitted by the IP network. In addition to transmission of the signals over an IP network, the interface can be configured to provide additional functionality including translation of the message protocol; connection of the interface to a network operations center; verification of message accuracy and completeness; acknowledgment of the receipt of a message; activation/deactivation of a message waiting indicator; connection to an SS7 network; back-up transmission between the IP network and the switch; and proxy/redirect of voice signals.
