The appearance of VoIP technology has now made feasible the use of data network for data, as well as voice communication. In this book, the protocol conversion between two different networks, packet scheduling and routing schemes for gateway selection has been introduced and also verified with Asterisk server. The recent trend for convergence of different access network technologies, market deregulation and emergence of dual-mode end-user devices allow the same destination to be reached by alternative paths and interfaces.Providing a good QoS in heterogeneous networks for irregular traffic flows remains a significant challenge. One of the difficult tasks is that of gateway location, also known as gateway selection, path selection, gateway discovery, and gateway routing. The main objective of this book is to design and develop a PSTN-IP Telephony Gateway (PITG) model and to assist routing packets while ensuring minimal call blocking probability with respect to call arrival rate or load, to increase the overall performance of the system. Specifically, the primary focus is on the development, analysis and optimization of the PITG model and evaluation of a gateway selection algorithm.

National Telecom Limited (NTC) was incorporated on June 8, 2004 for the purpose of implementing, owning and operating a fixed line network in Bangladesh. NTC was awarded a PSTN license by the Bangladesh Telecom Regulatory Commission (BTRC), and the Government of Bangladesh (GoB) to operate basic telephone services, data and broadband services in all over Bangladesh. The license was granted for a period of 20 years and is renewable prior to expiry. The authorised capital of NTC is Bangladesh Taka (BDT) 5 billion (approx US$ 73 million) divided into 50,000,000 ordinary shares of BDT 100 each. 1 US$ = 68.7 BD National Telecom, received a national license on 23 September 2007 and is one of the six PSTN operators to operate PSTN service all over Bangladesh. The license was granted for a period of 15 years and is renewable prior to expiry and NTC had to surrender all previous (four Zone) licenses. NTC also received one spot of 450 MHz and one spot of 1900 MHz frequency from BTRC.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.The public switched telephone network (PSTN) is the network of the world''s public circuit-switched telephone networks, in much the same way that the Internet is the network of the world''s public IP-based packet-switched networks. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital and includes mobile as well as fixed telephones. The PSTN is largely governed by technical standards created by the ITU-T, and uses E.163/E.164 addresses (more commonly known as telephone numbers) for addressing.
