Abstract

This hands-on workshop—which took place September 30 - October 1, 2004 in Austin, Texas—provided an overview of emerging voice over IP (VoIP) technologies, including: the session initiation protocol (SIP), IP-based voice disaster recovery, IP-TDM media gateways, and VoIP quality monitoring. Working in several small groups, attendees deployed several working VoIP systems in a testbed environment. Attendees learned to configure a SIP proxy, to add SRV and NAPTR records to DNS, and to provision SIP hard and soft phones.
