Online video telephony systems have been increasingly used in several industrial areas because of coronavirusdisease 2019 (COVID-19) spread. The existing session initiation protocol (SIP)-based video call system isbeing usefully utilized, however, there is a limitation that it is very inconvenient for users to transmit additionalinformation during conversation to the other party in real time. To overcome this problem, an enhanced schemeis presented based on augmented real-time reality (AR). In this scheme, augmented information is automaticallysearched from the Internet and displayed on the user’s device during video telephony. The proposed approachwas qualitatively evaluated by comparing it with other conferencing systems. Furthermore, to evaluate thefeasibility of the approach, we implemented a simple network application that can generate SIP call requestsand answer with AR object pre-fetching. Using this application, the call setup time was measured and comparedbetween the original SIP and pre-fetching schemes. The advantage of this approach is that it can increase theconvenience of a user’s mobile phone by providing a way to automatically deliver the required text or imagesto the receiving side.
