Current IP phone architectures which bring phone services to a distributed open environment are eraltively static and do not scale well. An IP phone environment should be more dynamic. Using Jini to be middleware for IP phone services will make the IP phone environment more portable, easier to deploy and straightforward to extend. However, many global applications with complex business logic an...

ABSRACT The objective of this proposal is to specify the algorithm to integrate mobile and LAN/WLAN with IP phone so that wireless system can work seamlessly together with wired system. By implementing this proposal, mobile phone can be power charged by IP, more granular location identification by IP, seamless roam and HO among wireless and wired IP networks. Calls can be routed based on the lo...

IP phones are an essential component of any VoIP infrastructure. The hardware constraints and newness of these devices, as compared to mature desktop or server systems, lead to software development focused primarily on features and functionality rather than security and dependability. While several automated tools exist to test the security of IP phones, these tools have limitations and can not...

Initially, Internet protocols were not designed for mobility nor were they designed for handling real-time services. Recent research e orts on Mobile-IP and RSVP are aimed at providing these features in the Internet. However, additional support is needed to provide real-time services for moving users. One such real-time service for mobile users is the concept of an Internet Cellular Phone. An I...

In this research, we propose an architectural solution to implement the voice over IP (VoIP) service in campus environment network. Voice over IP (VoIP) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to analyze the VoIP Codec se...

Voice over IP (VoIP) is a family of technologies, methodologies, communication protocols, and transmission techniques for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms frequently encountered and often used synonymously with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband tele...

This work presents an advanced service implemantation regarding an automatic control and management of phone channels bandwidth requirements over a Premium IP (PIP) network. This service is implemented by the SLAM (Service Level Agreement Manager) on the Intelligent Node based on the Active Network technology. During the last years “Voice over IP” (VoIP) and IP Telephony has gained an unprecede...

Japan has experienced two developmental stages in the mobile telephony innovation since 1979 when the first mobile phone was commercially launched. The stages can be identified as traditional mobile phone with only voice function and mobile phone with IP (Internet Protocol). This paper discusses how mobile phone with IP function offers diversified services, influences people’s daily lives by ch...
