Android - How to start Facebook Messenger Audio call from within my app?

Question

I already know how to start a Skype Call from within my app using this code:

    Intent skypeIntent = new Intent(Intent.ACTION_VIEW);
    skypeIntent.setData(Uri.parse("skype:" + skypeId + "?call"));
    context.startActivity(skypeIntent);

I would like to do the same thing using Messenger app.

I couldn't find information about that neither in the Messenger SDK , nor on the web.

Some related information I found, but no solution:

• I stumbled on this list of Uris, but none seems to be related to passing audio calls.
• how to start android facebook app chat from another app , but nothing about audio calls.

Can you please help?

Thanks
