open source voip software for ubuntu linux
Can anyone recommend a simple open source voip software in linux for pc-to-pc voice calls.
One requirement i that it should be simple with bare minimal functionality since I will be using as a part of a university project and so I don't want any additional features such as buddylist, GUI, etc.
Even a command line interface will also be fine since I am only interested to test different associated codecs/network characteristics.
The code should be simple with bare minimal libraries so that can be compiled easily.
I am aware of some open-source software such as WengoPhone but it seems that they have lot of associated features supporting different input devices with sophisticated GUI.
I require only PC-to-PC call functionality and I will be using within a LAN.
It will be very helpful if anyone can suggest any software!
