How to make free phone calls over broadband/ADSL
You often hear people talking about saving money by making phone calls over the internet. This may sound complicated but in reality it is easy. VoIP (Voice over Internet Protocol) is the term for voice communication over the internet.
VoIP requires a broadband / ADSL internet connection. In a previous post I explained what ADSL is and what equipment you need.
When you get started, try to use the same ITSP (Internet Telephony Service Provider) as the people you would like to phone most often. In order to phone people for free, you need to ensure that you are using the same provider.
Popular providers are SIP providers (e.g. Sipgate), Skype and Google Talk

i would love to see a massive price drop on internet phones coz i like to buy lots of em ”~
I use a ADSL modem to connect to internet. Would I be able to use the same line to make land line and mobile phone calls? If so, what equipments and how will I do that? Please assist me and shed some lights.
I am assuming by mobile phone you mean celll phone and not just a handsfree phone. I do not have experience with this, but my understanding is that you would need a smartphone (Apple iPhone or any Android smart phone for example HTC or Nokia) with some kind of softphone installed. Examples of softphones are Skype and Fring. You also require an ADSL modem with a wireless connection. So you connect from your mobile phone using wireless to the modem (adsl line) and then make a VOIP call to another person. the other person may require the same client (Skype / Fring).
