[Asterisk-Users] RTP Source IP Address

You can't. It's a bug in rtp.c. I've fixed it and posted a note to
asterisk-dev but my post wasn't forwarded to the list by the moderator (I
posted from an address different from the one I originally registered
because I couldn't remember what that was) and I've haven't had time to post
this to the bugs database.

If you are in a hurry email me directly and I can get you the patch to the
code.
