They are again converted back to the original data or the voice originally spoke by the previous party.

What are the main advantages of having Voice over Internet Protocol service?

Of course the money is what mainly matters. VoIP is unbelievably cheaper than normal telephone of mobile phone for both national and International telephone call. As I said earlier you can even get free call services from some of the VoIP service providers. Local calls are not a big problem but if you need to make International calls often then it's better for you to stick with VoIP. Virtual telephone number is another benefit of VoIP service. The number is like changes according to the places you are calling to. For example if you live in London and you wish to make a call to Amsterdam then you will be charged like you called from Amsterdam.

What are the must have things for VoIP telephone service?

Does VoIP service have any disadvantages?

As I said earlier although the sound quality of VoIP service is better than mobile phones it is still behind the landline phones and the quality is not guaranteed by the service provider. VoIP does not works if the internet connection goes down and the quality of the sound goes down according to the bandwidth of your Internet connection. Landline phone works even if the power is down but VoIP won't work for in such situations. So it's better to keep the landline phone also as the backup or for emergency purpose.
