Online voice-calls
Thanks to voice over internet protocol (voip) technology, you can have telephone-like communication via the internet. Many chat and instant messaging clients now support making VOIP calls and often provide this service free of charge. A popular VOIP service is Skype. With this you can call another Skype user anywhere in the world at no cost – as long as they also have an internet connection. Skype also allows you to buy credit to make inexpensive international calls to landline phones.
Other VOIP applications include:
- Qute.com (http://www.qutecom.org/)(formerly known as WengoPhone)
- Adium (ver. 1.0.2 -> 1.3.2; http://www.adiumx.com/)
- Colloquy (ver. 2.1 -> 2.1; http://colloquy.info/)
- Pidgin (ver. 1.5.0 -> 2.5.2; http://gaim.sourceforge.net/)
