Abatement of costs - The benefits of using innovative technology such as VoIP are many. It is one of the so-called "technologies of the future", which soon will replace the normal telephone which will become "obsolete". It allows a substantial reduction in costs, both for national calls and international or intercontinental (the cost of the call does not change whether you call your own country or the other side of the world).

Work facilitation - VoIP can be used both, for calls within the same company, or for more complicated features, such as teleconferencing in multi-point. You can also use a single integrated network for voice and data, which guarantees a reduction of total infrastructure needs and, in a business, simpler exchange of information.

Access to some services via the phone - If you decide to use the special VoiP telephone, unlike normal equipment, can be used both for normal conversations, and to have access to some Internet services, such as telephone list, obtaining a response in voice or text form.

More freedom - The versatility of this technology is significant as an employee, for example, in a call centre, can work directly in it's home or in the office, allowing benefits for both, the employer (saving) and for the employee (more freedom).

Increased fax efficiency - Even the transmission of data via fax will be facilitated by digital signal, a "package" being more functional than the standard dial-up PSTN which is used by ordinary fax (slower transmission).

Possibility of Number Portability - Moving to VoIP technology is not that you should lose your phone number, because, thanks to the Number Portability number remains the same! The NB is in fact a procedure that allows you to transfer phone numbers from one operator to another, you can then transfer the existing numbers on new VoIP lines (as is already possible for some time with various mobile operators), Saving, of course, royalties on existing fixed lines. You can also call from a laptop via Internet from any place with DSL (hotels, offices, houses, roads, villas, etc. through wireless connections).

Voice quality variable - The quality of voice reproduction can be changed as needed.

Greater privacy - Calls via VoIP are safer than normal calls, even if they are not encrypted. To be able to intercept a communication VoIP, one must have access to the devices that make up the VoIP network and /or Internet network. The authentication which allows to identify departures calls is protected by a memorandum of hashing, very difficult to deceive.
