Abstract
Systems and methods for monitoring a call directed to a telephony network-based voice messaging service (VMS) implemented using packet-switched data network telephone conferencing resources, such as an IP-based voice-over-IP conferencing system. The systems and methods use one or more media gateway systems providing an interface between a conventional telephony domain and packet-switched data domain. When a call is to be redirected to the VMS system, the telephony network routes the call via the packet-switched data network using the media gateway. An application server in the packet-switched data network maintains registration information associated with the subscriber. If the subscriber is logged onto the packet-switched data network, the conferencing resources are used to establish a conference call between the caller, the VMS and the subscriber.
