VoIP telphony (Voice over Internet Protocol) lets making calls to landlines or mobiles with cheap prices.

Requirements

If you want to make VoIP calls you have to do 3 things:

1. Create an account on any VoIP provider web side.

2. Pre-paid your account.

3. Install one of available VoIP application.

VoIP providers

There are two providers I tried by myself, more you can find on a web side below.

1. Skype Out http://www.skype.com/intl/en-gb/features/allfeatures/call-phones-and-mobiles/

2. Freeconet http://www.freeconet.pl/en/

Kphone

Kphone is very small but fully working VoIP application.

1. Installation:

apt-get install kphone libqt3-mt

2. The installation script doesn't make Menu entry, so you can do it yourself:

sux
mousepad /usr/share/applications/kphone.desktop

copy and past text below in:

[Desktop Entry]
Name=Kphone
Comment=VoIP telephony
Exec=kphone
Icon=/usr/share/icons/oxygen/64x64/apps/internet-telephony.png
Terminal=false

and save the file (the icon patch can be vary).

3. Run it from: Menu-> Network-> Kphone

4. As a first step configure your account:

a. In "User part of sip URL" type your user name or number you got from VoIP provider.

b. In "Host part of sip URL" type VoIP provider sip address such as: sip.address.com
