The Internet and IP-based networks are increasingly being used as alternatives to the public switched telephone network. Internet Telephony Service Providers (ITSPs) can provide voice and fax services which are close to becoming functionally equivalent to those provided by public telecommunication operators (PTOs).

IP telephony technology has become a reliable communication option that has well-established standardized communication protocol. IP Telephony systems have many low cost devices and software application development tools available compared to proprietary telephone systems and services. The use of IP Telephony products and software allows companies to cost-effectively upgrade and eventually replace existing (legacy) telephone systems with more cost effective and easy to use telephone equipment.

IP telephony provides a way for you to extend consistent communication services to all your employees, whether they are in main campus locations, at branch offices, or working remotely. IP telephony transmits voice communications over a network using open-standards-based Internet Protocol.A good IP telephony solution increases productivity and enables business process improvement by simplifying and streamlining communications.

Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. Some VoIP services may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers.

There are 3 main causes for the evolution of the Voice over IP market:

  • Low cost phone calls
  • Add-on services and unified messaging
  • Merging of data/voice infrastructures

A VoIP system consists of a number of different components: Gateway/Media Gateway, Gatekeeper, Call agent, Media Gateway Controller, Signaling Gateway and a Call manager.

The following are examples of services provided by a Voice over IP network according to market requirements:

Phone to phone, PC to phone, phone to PC, fax to e-mail, e-mail to fax, fax to fax, voice to e-mail, IP Phone, transparent CCS (TCCS), toll free number (1-800), class services, call center applications, VPN, Unified Messaging, Wireless Connectivity, IN Applications using SS7, IP PABX and soft switch implementations.
