The voice over IP or Internet telephony solutions have become very popular in these early years of the 21st century. With its two main benefits in terms of cost advantages and simplicity, this technology is opening up new horizons in the telecommunications industry. The companies, big or small, have entered the field of internet telephony for reaping significant profits- more so when compared to the PSTN services.

Apart from this, there are other many reasons for switching over to VoIP services such as:

1.Cost effective calling: With the adoption of these services, the users can save significant amounts of their money on monthly telephone bills. As a matter of fact, by dropping traditional phone services altogether, the users can save around 40 to 60 percent each month on their phone bills.
2.Affordable long distance calling: The users can enjoy making cheap long distance calls as well as cheap international calls. This is because the internet telephony solutions are based on the packet switching technique wherein calls are routed over the internet. Unlike PSTN service, the calls are not charged according to the distances.
3.Unified communication: In this advanced solution, the users can share the data, video, images as well as text with near and dear ones. The internet telephony solutions provide a unified communication with others as the packet switching technique is used.
4.Free Calling Features: The VoIP calls ensure that the users are able to enjoy a wide variety of free calling features. Unlike PSTN services, in the internet telephony solutions, the users can enjoy value added calling features such as voice mail, caller ID, call conferencing, call waiting and call forwarding.
5.Convenience: Apart from the value-added features, the feature that the VoIP users can enjoy the most is the convenience of making cheap long distance calls. They can carry the VoIP phones along with them without incurring any additional charges, regardless of geographical location.
6.Mobility: Unlike PSTN services, the users can opt for the IP services from anywhere in the world, as internet is used for transmitting the calls instead of coaxial wires. With a high-speed internet connection and the VoIP phone adapter, the users can make and accept VoIP calls from any location at any time at no additional charge.

To conclude, the benefits and features are purely dependent upon the service provider. So, selection of a provider requires great caution. Moreover, the call termination contributes in increasing the efficiency of the entities going in for this change. At the same time, it lowers down on the monthly telephone bills, improves productivity, ensures excellent voice quality and does away with latency.
