International VoIP Calls

International VoIP Calls are really cheap — much cheaper than similar calls from a traditional phone service or even a calling card.

International VoIP calls use a local server in the country being called (also known as the international destination) instead of the network of expensive long-distance callers of yesteryear.

International VoIP works the same way regular VoIP works (learn How VoIP Works here): audio codecs compress the call and transmit it digitally over Internet Protocol to a local or regional destination, where the call unloads onto the local public telephone network or the appropriate VoIP network.

Some VoIP providers offer a certain amount of free international minutes with their VoIP service plan.

Consider, with us, what international calls were like before VoIP made things less expensive?

Challenges for International VoIP

Though effective, there are some roadblocks for International VoIP

1. Different Codecs

Audio codecs (which convert the sound of your voice to data packets that the Internet can transport) occassionally vary between countries and VoIP providers. That's a hurdle that VoIP providers usually manage pretty easily.

2. VoIP is not available in all countries

In some countries, it is illegal to use or sell VoIP. Obviously, in these countries, you can't make international calls with VoIP.

3. International VoIP and Telephone Networks

The biggest limitation for international VoIP calls is the quality of the phone network in the international destination.

International calls to developing countries are much more expensive than international calls to developed countries; it is much cheaper to call from the US to Europe than to call from the US to Central Africa. Calls to extremely remote locations are even more expensive (like Antartica).

However, for the most part, international calls with VoIP are much cheaper than international calls with any other calling method.
