Correct, seems like the port conversion is not happening. Can you check your alarm history under the Diagnostcis section of sipXconfig to see if the sipXproxy complains about not being able to enable the NAT traversal service? Also, did you restart the sipXproxy and sipXrelay services after you have finished configuring the NAT traversal feature on sipXecs? WRT to your port range, I don't think its wide enough. You may have hit on a bug here but I believe that you need a minimum range of 8 (sipXconfig should really police that) > > I don't know if sipXproxy is responsible for this > substitutions, probably it is responsibilities of sipXrelay. > I have tried everything in configuration, but this one I > cannot resolve. > I have tried even this > http://sipx-wiki.calivia.com/index.php/Configuring_remote_work > ers_cheatsheet. > Still no luck. There is a new and improved wiki section covering the NAT traversal feature.
