Design and Implementation of SIP based VoIP Application for Mobile Devices using J 2 ME
نویسندگان
چکیده
Voice over Internet Protocol (VoIP) is a way to carry out a telephonic conversation over a data network. VoIP applications, with SIP and RTP, promise converged telecommunications and data services that are cheaper, more versatile and provide good voice quality as compared to traditional offerings. Although VoIP is widely used, VoIP on mobile devices is still in its infancy. Currently, there are number of VoIP solutions for mobile phones, however VoIP solutions developed using Java 2 Platform Micro Edition (J2ME) are not available. Java based solutions are widely compatible with many devices. In this paper strong focus has been given to cross-device compatibility through the use of the widely supported J2ME framework. The design and implementation details of VoIP client using J2ME are illustrated.

Security testing of session initiation protocol implementations
The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...

The SIP protocol was standardized by the IETF at the application layer for initiating, managing, and terminating multimedia sessions and has been widely used as the main signaling protocol on both the Internet and VoIP networks. Most challenges in this protocol are overload and lack of proper state distribution. These challenges cause a wide range of next-generation network users to face a shar...

Increasing the popularity of SIP based services (VoIP, IPTV, IMS infrastructure) lead to concerns about its security. The main signaling protocol of next generation networks and VoIP systems is Session Initiation Protocol (SIP). Inherent vulnerabilities of SIP, misconfiguration of its related components and also its implementation deficiencies cause some security concerns in SIP based infra...
متن کاملIntelligent VoIP System in Ad-Hoc Network with Embedded Pseudo SIP Server
Wireless networks and the voice over Internet protocol (VoIP) have recently been widely adapted. VoIP services over Ad-hoc network can be accomplished by middleware embedded in mobile devices. In this study, we have implemented an intelligent VoIP system with embedded pseudo session initiation protocol (SIP) server in an Ad-hoc network. We employed the standard SIP protocol and integrated SIP p...
متن کاملBare PC SIP User Agent Implementation and Performance for Secure VoIP
Bare PC systems, which run applications without using any operating system (OS) or kernel, are immune to attacks targeting a specific OS. They also perform better than conventional systems due to their reduced overhead. We describe the design, implementation and performance of a SIP user agent (UA) for secure VoIP on a bare PC system. In particular, we discuss SIP functions and message handling...
