Viber as a SIP Trunk?

Hi everyone,

I just read news that Viber allows free calls to landlines around the world. I don’t know much (or anything) about how Viber works, so I ask the more knowledgable community here. Is it possible to use Viber as a trunk in FreePBX/Asterisk?


My Config:
Asterisk (Ver. 11.7.0)
