Session Initiation Protocol (SIP) is an application layer protocol designed to control and establish multimedia sessions over internet. SIP gaining more and more popularity as it is used by numerous applications such as telephony over IP (ToIP). SIP is a text based protocol built on the base of the HTTP and SMTP protocols. SIP suffers from certain security threats which need to b e resolved in ...

This document provides a terminology for benchmarking the Session Initiation Protocol (SIP) performance of devices. Methodology related to benchmarking SIP devices is described in the companion methodology document (RFC 7502). Using these two documents, benchmarks can be obtained and compared for different types of devices such as SIP Proxy Servers, Registrars, and Session Border Controllers. T...

BACKGROUND Antimicrobial prophylaxis is commonly administered to patients undergoing left ventricular assist device (LVAD) surgeries to prevent infectious complications. However, optimal surgical infection prophylaxis (SIP) for LVAD surgeries is not well defined. METHODS We conducted an electronic survey to characterize LVAD SIP used at different centers performing LVAD implantation. RESULT...

Two studies describe the development of a comprehensive, vignette-based measure of social information processing (SIP) particularly relevant for children with internalizing problems. Study 1 (N = 219 3rd-6th graders) describes the creation of the Children's Evaluation of Everyday Social Encounters Questionnaire (ChEESE-Q) and evidence for its reliability and validity, including internal structu...

The Session Initiation Protocol (SIP) has become the most predominant protocol for Voice over Internet Protocol (VoIP) signaling. Security of SIP is an important consideration for VoIP communication as the traffic is transmitted over the insecure IP network. And the authentication process in SIP ranges from preshared secret based solutions to Public Key Infrastructure (PKI) based solution. Howe...

layer signalling protocol, SIP offers mobility management capability. However SIP Terminal Mobility suffers from considerable handoff latency which is unsuitable for real time applications and frequent local movements (intra domain handoffs). Hierarchical Mobile SIP (HMSIP) was then proposed as a solution to reduce the SIP handoff delay and to provide a complete micro-mobility solution for SIP ...

OBJECTIVE To determine the effectiveness of the use of the SIP score and the quality of life impairment in patients with ileal conduit and orthotropic ileal derivations by Hautmann and AbolEnein/Ghoneim. METHODS Prospectively evaluated 146 patients in different age groups. In 66 patients ileal conduit derivation was performed, in 20 patients orthotropic derivation using Hautman technique was ...

The IP multimedia subsystem (IMS) is a basis for a significant new architecture which offers network operators the opportunity to expand their services, by integrating voice and multimedia communications and delivering them into new environments with new purposes. Basically, the IMS is an overlay network on top of IP layer that uses Session Initiation Protocol (SIP) as the primary signaling mec...

BACKGROUND Sipuleucel-T (SIP-T), which functions by stimulating cancer-specific dendritic cells, prolongs survival in men with prostate cancer. Ipilimumab (IPI) achieved a borderline survival advantage in a large randomized trial. SIP-T and IPI are potentially synergistic. PATIENTS AND METHODS Nine men with progressive metastatic castrate-resistant prostate cancer (mCRPC) were treated prospec...

Objective: Spontaneous intestinal perforations (SIP) in extremely low birth weight infants are distinctly different from necrotizing enterocolitis. The etiology of SIP is not well understood. Our objective was to identify perinatal therapeutic interventions that may increase the risk of spontaneous intestinal perforations. Methods: Medical records of extremely low birth weight infants (BW<1000g...
