Abstract: Methods and systems are disclosed that allow for the exchange of voice mail messages between different VMSs of different service providers and/or in different networks by the transmission of such messages through a data network using a standard protocol of the data network. Methods and systems also are disclosed that validate message transactions among subscribers receiving regional messaging services over the PSTN. The subscribers are located in different geographic areas and may be provided their voice, facsimile or data messaging services by different companies. The present invention validates passing messages (data) among customers of potentially different companies located in different areas by assessing the validity of the transaction in light of a number of conditions, including applicable regulatory or business conditions.

Abstract: An Internet Call Waiting—Voice over Internet Protocol (ICW-VOIP) service that uses a service control point and service node of a Public Switched Telephone Network (PSTN), acting as a gatekeeper and bridge respectively, to enable ICW subscribers to answer telephone calls during an internet session without having to disconnect internet access. The primary network components of the ICW-VOIP service comprise a proxy firewall, a service node, and a gateway. When a PSTN call is placed to a subscriber whose line is being used for internet access, the service control point accesses the subscriber's internet address from a database and transmits a message over the internet to the subscriber giving the subscriber the option to accept the call as a VOIP call. Once accepted, the subscriber places an H.323 call through the gateway to the service node. The service control point also forwards the PSTN call to the service node. Using bridging information, the service node matches the subscriber H.
