hese reforms have remarkably marked the advent of the real integration of the Indian economy into the global economy.  In context to India, Globalization implies opening up the economy to foreign direct investment by providing facilities to foreign companies to invest in different fields of economic activity in India, removing constraints and obstacles to the entry of MNCs in India, allowing Indian companies to enter into foreign collaborations and also encouraging them to set up joint ventures abroad. As a result of opening Indian economy to foreign market, there was the need for international communication.

A service provider may charge you somewhere between INR 25 – INR 150 to make an international call. The service provider charge different rates in different countries depending on the policy of the respective country. The cost of communication is expensive and the frequency of communication is increasing due to increased globalization of trade. In all, the increasing cost of communication has become heavy for MNCs. As it is there is recession in economy and making super expensive long distance calls is not a feasible method. Therefore a new method of communication has gained importance which helps you make long distance calls for free. It is called VoIP (Voice over Internet Protocol) voice over ip phone systems .

If you've never heard of VoIP, get ready to change the way you think about long-distance phone calls. VoIP, or Voice over Internet Protocol, is a method for taking analog audio signals, like the kind you hear when you talk on the phone, and turning them into digital data that can be transmitted over the Internet. VoIP is a revolutionary technology that has the potential to completely rework the world's phone systems. VoIP sounds almost magical: The hype makes it sound more flexible, more full-featured, and best of all, significantly cheaper than placing your calls through traditional telephone service providers. One of the most common uses of VoIP service is through IP Phones.

An IP telephone system uses packet-switched Voice over IP (VoIP), or Internet telephony, to transmit telephone calls over the Internet as opposed to the circuit-switched telephony used by the traditional Public Switched Telephone Network (PSTN). Also known as VoIP phone systems, IP telephone systems typically comprise a VoIP private branch exchange (an IP PBX) and desktop VoIP phones (IP Phones) that connect to a VoIP service provider via a Local Area Network (LAN).These specialized phones look just like normal phones with a handset, cradle and buttons. But instead of having the standard RJ-11 phone connectors, IP phones have an RJ-45 Ethernet connector. IP phones connect directly to your router and have all the hardware and software necessary right onboard to handle the IP call. Wi-Fi phones allow subscribing callers to make Ip Voice from any Wi-Fi hot spot.

One of the key advantages to IP telephone systems is that whereas long-distance calls on a regular phone system can be cost prohibitive, the same calls on an IP phone system are free -- there are no fees beyond the cost of Internet access. The practical upshot of this is that by using some of the free VoIP software that is available to make Internet phone calls, you're bypassing the phone company (and its charges) entirely. There are many free VoIP software available on the Internet. You can download them and set it up in about three to five minutes and be ready to make free long distance call at no cost.
