4. What kind of equipment do I need to make a VoIP call?

For any type of call, the user needs to conclude a contract with the Internet Service Provider (ISP) which preferably provides broadband Internet access through an ADSL or cable modem.

As regards PC-to-PC calls (between personal computers) or PC-to-telephone calls (between a personal computer and an analogue telephone), you need a personal computer with the minimum recommended configuration and a microphone, headphones being likewise advisable in order to avoid feed-back which occurs when you use both microphone and speakers.

As far as telephone-to-telephone calls are concerned, the user needs to have a router/switch to which the modem and the IP telephone must be connected. If you only have an analogue telephone, you need an adaptor to connect it to the router/switch.
