Hi Daniel,<BR> <BR>What does the log below means? Does it mean nathelper has issue to send the request to RTP proxy first or nathelper doesn't receive a response after sending a request to the rtp proxy?<BR><FONT color=#ff0000>0(27429) ERROR: nathelper [nathelper.c:2457]: can't send command to a RTP proxy<BR></FONT></BLOCKQUOTE>this error is printed when write to socket fails.
