[Enhancement] add freePBX.

[miroslavpejic85]

First of all, thanks for this nice project.

It would be great to add an asterisk freePBX, in order to have a UI and write a steps to make a simple call between 2 simple accounts.

PROS: Even novice users could interface with the app and it would become more engaging and interesting!

keep it up!
