The VoIP communication system at OMNI Hospital Alam Sutera uses the Elastix 2.5 server with the Centos 5.11 operating system. Elastix 2.5 by the developer has been declared End of Life. The server security system is a serious concern considering that VoIP servers can be accessed from the internet. Iptables and fail2ban applications are applications that are used to limit and counteract those who try to attack the VoIP server. One application that can be used as an open source VoIP server is the Issabel Application version 4.0. The migration process from Elastix 2.5 application to Issabel 4.0 by backing up all configurations in the Elastix 2.5 application through a web browser including the configuration of endpoints, fax, e-mail, asterisk. After the backup file is downloaded then upload the backup file to the Issabel 4.0 application then run the migration process. Adding a backup path as a failover connection is needed because the VoIP communication protocol between the OMNI Hospitals Group still uses one path so that when there is a problem in the connection path, the communication protocol will stop. The tunnel EoIP is a protocol used as a backup path between the OMNI Hospitals Group site.

The increasing prominence and variety of open source software (OSS) threaten to upset conventional approaches to software development and marketing. While a tremendous amount of scholarship has been published on the differences between proprietary and OSS development, little has been discussed regarding the effect of rhetorical appeals used to promote either type of software. This chapter offers just such an examination, focusing its scrutiny on the websites for three pairs of competitors (operating system, Web browser, and image manipulation program). The means by which the OSS websites promote their programs provide a significant set of insights into the potential trajectory of OSS development and its widespread public acceptance, in terms of both its initial philosophy and its perceived alternative nature to traditional software products and models.

Future Business

The popularity of open source software (OSS) has exploded among consumers and software developers. For example, today, the most popular Web server on the Internet is Apache, an open source product. Additionally, Linux (often considered one of the perfect examples of OSS) is now contesting Microsoft’s dominance over the operating system market. OSS’ flexibility, moreover, has allowed it to become a key international technology that could affect developments in global business practices. Despite these beneficial aspects, there are those who would claim it is difficult to implement and its core developers are undependable hobbyists. The purpose of this paper is to provide the reader with an overview of what OSS is, to present some of the benefits and limitations of using OSS, and to examine how international growth in OSS use could affect future business practices. By understanding these factors, readers will gain a better understanding of it and how OSS can be integrated into their organizational computing activities.

One may expect the Internet to evolve from being information centric to knowledge centric. This paper introduces the concept of a Knowledge Society Operating System (KSOS) that allows users to form knowledge societies in which members can search, create, manipulate and connect geographically distributed knowledge resources (including data, documents, tools, people, devices, etc.) based on semantics (“meaning”, “intention”) in order to solve problems of mutual interest. Built on top of the current Internet infrastructure, a KSOS can take advantage of existing resources to enable the use of applications or services through a web browser. This paper discusses some crucial aspects of a KSOS.
