Linux Tools for Voice over IP
CALLING THE WORLD
This month we’ll show you some popular Linux tools for Internet telephony
Voice over IP (VoIP) refers to the set of technologies providing voice communications over TCP/ IP networks. Of course, the biggest TCP/ IP network is the Internet itself, and the ultimate goal of the VoIP industry has always been to find a way to use the Internet for ordinary phone calls. Early VoIP efforts faced several challenges, including quality of service issues, hardware issues, and a general lack of bandwidth. If you’ve been reading the Internet ads recently, though, you’ll have noticed that these issues have largely been addressed. Internet phone services are quickly becoming popular around the world.
