      He could have a "denial of service" detection on his network that would
      cause streaming UDP packets to become blocked.

      He may also have directional rule setup such that his network will not
      accept packets until it has sent packets to that system first, on those
      ports. That should still work, but any combination of the above could
      cause problems.

      The main issue is if you do not know what is on the network, then you
      should look for another network :)

      You say "no audio back" do you mean "no key up back" or do you get a
      dead-air key up?
