Yes:
http://www.ekiga.org/index.php?rub=3&pos=0&faqpage=x161.html#AEN163
"If it reports "Symmetric NAT" and that you are not using GNU/Linux,
then you are not part of the 99% of lucky users. You will have to
forward UDP ports 5000 to 5100 to your internal machine. Run the test
again, it should report "Cone NAT" or "Port Restricted NAT" and it will
work."

If you can not forward ports:
http://www.ekiga.org/index.php?rub=3&pos=0&faqpage=x161.html#AEN196
"Please make sure you have read this FAQ correctly because it should
work in all cases. The worst case is when you have to forward ports. If
you can not forward ports, or if you do not want to do it, you have
alternative solutions. For SIP, you can use SIPROXD as outbound proxy.
For H.323, please configure the GNU Gatekeeper as a proxy."

TURN and ICE are great, but only if you have TURN servers proxying the
RTP streams. Such servers do not exist yet, so it would not solve your
problem.
