VOIP has become a force to reckon with in the telecom sector with many people and businesses saving considerable time and resources by opting for a relatively inexpensive voice over internet protocol . VOIP has many advantages , follow here:
- The main advantage is the amount of money you end up saving on your phone bills as compared to a traditional phone line.
- Inexpensive and easy to use. Since it is simple, upgrading is relatively simpler too.
- You can integrate it with an existing phone connection.
- With VOIP PC-to-PC, calls are free no matter the distance and PC-to-Phone charges are nominal.
- For a monthly fee you may make unlimited free calls within a geographic area.
A virtual number enables you to make calls from anywhere as long as a broadband connection is available.
- You may purchase a number in a geography area of your choice, which works out very cheap.
-You may access your VOIP account just like your email Id from any where in the world as long as you have an internet phone. This makes it easy for those who travel frequently to make calls frequently to those back at home at local call rates, no matter where they are.
