This module focuses on how we interface legacy PSTN services with an H.323 network. First, we trace the steps involved in setting up and tearing down an H.323 call. Next, we explore how we can translate Signaling System 7 (SS7) interswitch signaling into packetized network traffic, carrying such advanced call features as call forwarding, calling and called party identification information, and 3-way calling. We explore how ISDN-based services, such as Digital Signaling System 1 (DSS1) and Q.SIG, enable the integration of disparate voice and messaging systems. We discuss how we interface ISDN, frame relay, and Asynchronous Transfer Mode (ATM) services with the VoIP network. We finish this module by discussing fax over IP (FoIP) services.
