to tell the truth, the basic stun dialogue has been recently
revised (in rtp.c) and used in chan_sip.c for the main
socket. Adding stun support to the RTP streams is certainly
welcome, but in the simplest form is as trivial as adding this call

	ast_stun_request(rtp->s, &stunaddr, NULL, &rtp->us);

right after the call to ast_rtp_new_with_bindaddr()

The reason i have not done it yet is because the call is blocking,
and i am trying to figure out a better way to do it. If you do
have a solution to this problem i'd love to hear.
