Hi, I'm having a problem with RTP traffic, I have softphone connecting<br>
from the outside, I can register but Kamailio is sending all RTP traffic<br>
to the private IP address that the softphone has in it own local<br>
network. How can I fix this? Any help will be appreciated.<br>

That is what the far-end NAT traversal / rtpproxy part of Kamailio functionality is for.<br>
