 As a IP telephony protocol, the SIP is gaining increasing popularity. There is yet POTS(Plain Old Telephone Service) line as the existing subscriber line. The Megaco/H.248 may be used for call between the POTS line and SIP. So, it is needed that method for interworking between Megaco/H.248 and SIP. In this paper, we propose the implementation of Residential Media Gateway Prototype in Interwor...

BACKGROUND A number of studies have shown that bite and sip sizes influence the amount of food intake. Consuming with small sips instead of large sips means relatively more sips for the same amount of food to be consumed; people may believe that intake is higher which leads to faster satiation. This effect may be disturbed when people are distracted. OBJECTIVE The objective of the study is to...

Two studies examined shared and unique relations of social information processing (SIP) to youth's anxious and depressive symptoms. Whether SIP added unique variance over and above trait affect in predicting internalizing symptoms was also examined. In Study 1, 215 youth (ages 8-13) completed symptom measures of anxiety and depression and a vignette-based interview measure of SIP. Anxiety and d...

In the 3rd generation multimedia communication world and in the 3GPP standardization consortium, SIP protocol appears to be the preferred signaling protocol. However, the need to communicate with non-SIP based network, e.g. H.323 from ITU-U, is still a reality. The need can be satisfied with the introduction of network gateways (also named Inter-Working Function). One of the open issues about S...

SIP is evolving as the dominant protocol for multimedia call control in IP networks and is expected to be widely deployed in the near future. Using SIP for supporting mobility in SIPbased networks appears as a very attractive alternative to Mobile IP, taking advantage of existing SIP infrastructure and signaling, while avoiding duplication of functionality. However, existing proposals for suppo...

OBJECTIVE Prophylactic indomethacin reduces severe intraventricular hemorrhage but may increase spontaneous intestinal perforation (SIP) in extremely low birth weight (ELBW) infants. Early feedings improve nutritional outcomes but may increase the risk of SIP. Despite their benefits, use of these therapies varies largely by physician preferences in part because of the concern for SIP. METHODS...

In certain types of multimedia communications, a Session Initiation Protocol (SIP) request is distributed to a group of SIP User Agents (UAs). The sender sends a single SIP request to a server which further distributes the request to the group. This SIP request contains a list of Uniform Resource Identifiers (URIs), which identify the recipients of the SIP request. This URI list is expressed as...

This paper describes an attack-directed approach to test SIP authentication vulnerabilities in session establishment and user registration. This approach aims to exercise the known areas of weakness including the inherent vulnerabilities in SIP specification and the implementation vulnerabilities caused by programmers’ negligence. By using this approach and a self-made testing tool, we have suc...
