A telephone call goes through six basic stages: (1) detection of a service request, (2) interpretation of the digits dialed, (3) alerting the called customer, (4) establishing a talking connection, (5) call disconnect, and (6) charging. The way in which programs, assisted by circuits and temporary memory, advance a call from one stage to another in no. 1 ESS is described in this article.

Most customers placing a direct-distance-dialing (DDD) call in the United States are able to complete the call on the first attempt. However, it is reasonable to expect that the probability of an initial completion will be less than 1. When an initial attempt fails to complete, a customer may decide to abandon his desired telephone connection or to make one or more retrials. In general, a sequence of one or more attempts may be initiated by a customer in an effort to establish the desired connection. ...

Recently, real-life data have revealed that the number of calls originating from or received by a telephone number in a network follows a power-law distribution. They show that a few telephone numbers make or receive a very large number of calls, whereas a large number of telephone numbers make or receive very few calls. The data have overthrown the general assumption that all telephone numbers are similar in generating telephone traffic. The first objective of this paper is to therefore construct ...

The ability to transmit and process voice over Internet protocol (VoIP) networks has important implications for technology managers. Many companies today are rushing to bring different VoIP products to market with a wide variety of features. Managers will need to understand the tradeoffs associated with VoIP as compared to the Public Switched Telephone Network (PSTN). This paper measures the preference structures between IP telephony and PSTN services using conjoint analysis. The purpose is to suggest ...

The performance analysis of blended PSTN and IP call centers is likely to be in demand in the near future as the technology for these centers develops further. The authors did not find an analysis for a system of this type in the literature. The development of a user-friendly and portable tool based on their analysis methodology should be useful to organizations that have implemented, or are considering implementing, a blended call center. We have shown BCAT's wide range of uses. In the future, ...

The Session Initiation Protocol (SIP) is considered to be a future powerful alternative to the H.323 standard as the signalling system for the dominant Voice over IP (VoIP) communications. This paper provides an in-depth analysis of SIP by describing the SIP protocol stack, summarising the main features of the protocol, and illustrating its architecture, message and operation. The paper also explains the architecture and the two key aspects of signalling interworking when SIP is interconnected with ...

VoIP (Voice over IP) over mesh networks could be a potential solution to the high cost of making phone calls in most parts of Africa. The Village Telco (VT) is an easy to use and scalable VoIP over meshed WLAN (Wireless Local Area Network) telephone infrastructure. It uses a mesh network of mesh potatoes to form a peer-to-peer network to relay telephone calls without landlines or cell phone towers. This paper discusses the Village Telco infrastructure, how it addresses the numerous difficulties associated ...

Voice over Internet Protocol (VoIP) is one of the fastest growing and most misunderstood technologies in the world at the moment. Confusion, outdated beliefs and urban mythology reign over such simple issues as how it works, the quality of the calls, and, of course, how much it costs. This paper examines seven existing myths about VoIP. These myths are that: (1) VoIP is free; (2) the only difference between VoIP and regular telephony is the price; (3) the quality of service isn't an issue nowadays because ...

The architecture addresses scalability and availability requirements of mass-market deployment of carrier-grade services and supports interconnection with SS7 for Internet telephony calls to the public switched telephone network.

Network gateways are used to set up calls between the public switched telephone network (PSTN) and the Internet, but existing gateways support a relatively small number of lines. To meet the scalability and availability requirements of mass-market deployment of carrier-grade telephony services, the authors propose an architecture based on the decomposition of Internet gateway functionality. The media transformation function of today's H.323 gateways is separated from the gateway control function, ...
