VoIP has significant potential in India due to the large number of global enterprises operating there. However, its growth is restricted by regulations prohibiting VoIP gateways within India. Enterprises are consolidating PSTN and VoIP networks using logical partitioning to reduce costs while complying with regulations. The grey market also poses challenges, with unlicensed providers stealing large volumes of business from licensed operators.
This document provides a summary of integrating IP telephony into the public switched telephone network (PSTN) environment. It discusses the evolution of PSTN from analog to digital networks and the emergence of time division switching. It then outlines the architecture of a soft switch solution for integration, including edge, core, control, and application layers. Finally, it discusses existing practices for integration, such as replacing tandem exchanges, and considers the specific context of integrating IP networks in Bangladesh.
VoIP (voice over internet protocol) allows users to make phone calls using an internet connection rather than a regular phone line. The key advantages of VoIP include lower call costs, the ability to make phone calls from any internet connection, and additional features like video calling. However, early VoIP systems in the 1990s suffered from low quality, disconnections, and delays due to lost or out of order packets over the internet. Modern VoIP systems have improved quality with the use of gateways between internet and phone networks, as well as improved encoding techniques.
The document discusses Internet telephony and Voice over Internet Protocol (VoIP). It defines IP telephony as using Internet protocol to exchange voice, fax, and other information traditionally carried over telephone networks. VoIP aims to standardize IP telephony. The document then describes how a VoIP call is completed by digitizing, compressing, and transmitting voice data over the Internet in packets before reassembling it at the destination. It notes benefits of IP telephony include potential cost savings compared to traditional telephone networks.
This seminar presentation provides an overview of Voice over Internet Protocol (VoIP) technology. It discusses how VoIP works by converting voice signals to digital signals sent over the Internet via packet switching. It covers major components of VoIP networks like codecs, quality of service issues, and types of VoIP services.

This document discusses VoIP (Voice over Internet Protocol) techniques and challenges. It begins by introducing VoIP as an alternative to traditional PSTN telephone networks that transmits voice over internet and packet-switched networks more cheaply. However, ensuring high quality of service (QoS) with factors like jitter, packet delay/loss, and bandwidth allocation presents major challenges for VoIP systems. The document goes on to describe how VoIP works by carrying voice in RTP packets within IP packets and discusses challenges to VoIP performance and QoS from system capacity, packet loss, delay, jitter, echo, and security.
This document provides an overview of VoIP techniques and challenges. It begins with an introduction to VoIP and what it is. It then discusses quality of service (QoS) and the importance of providing prioritized delivery services for applications like VoIP. The main challenges for VoIP are then outlined as system capacity/available bandwidth, packet loss, delay/network latency, jitter, echo, and security. Specific causes and issues are described for each challenge. The conclusion is that while VoIP provides a cheaper alternative to PSTN, it has lower quality of service due to these challenges, and the internet is not perfectly designed to carry voice.
An IP PBX phone system uses internet protocol over a data network to provide voice or video communication in a more cost effective way than traditional PBX systems. It offers benefits like lower installation, maintenance and long distance costs. Businesses can use their existing computer network without needing a separate phone system infrastructure. The IP PBX system also provides more features and flexibility than conventional phone systems.
VoIP is an emerging technology that uses the internet to transmit phone calls rather than traditional telephone networks. It has the potential to significantly lower phone costs for consumers while improving quality. VoIP services are already commercially available and most are low cost or free. However, the existing telecommunications regulations only apply to traditional phone networks, so a new regulatory framework is needed to address VoIP. Both incumbent phone companies and new internet-based companies see opportunities in VoIP, but there are debates around how it should be regulated.
