Why not? If the client that's behind the NAT is able accept media directly from Asterisk (which is in the public network), it should be able accept media directly from another client. Otherwise, the whole STUN scheme is not going to work.

No, it won't. If one of the clients is behind a NAT firewall, you cannot
tell that firewall to start accepting media directly from the other client.

In some situations it _may_ work, but it is not reliable.
