Best answer:

Answer by David C

VOIP is where sound (voice) signals are encoded and sent over an IP network (ethernet).

So, instead of the POTS (plain old telephone system) that charges you to call everyone, you can use the IP infrastructure (Internet) to speak with people in realtime anywhere in the world.

How can you configure it? That depends on what kind of system you have.

Advantages: Crystal clear, high quality audio anywhere in the world at a fraction of the price.

Disadvantages: If your IP network is down, so is your VOIP.
