Comment # 7 on bug 4612 from Vitaly Zaitsev

> Why does this qualify for rpmfusion repo?

Libtgvoip requires part of webrtc project - patented echo cancellation
algorithms. Without it it will be useless.

webrtc-audio-processing package available in Fedora repositories, but eac and
some other patented algorithms are removed from library and development
package.

We need to create webrtc-audio-processing-freeworld package or I can bundle it
in package (bundled version use only eac, not whole webrtc library).
