I can't confirm what kapetr says here, but if it is true you may have
better luck with a SIP account from iptel.org.  You can use it with your
Ekiga software.  They claim to have a server-side workaround for the NAT
problem, without using STUN.  I briefly tested it and it seems to work.
Give it a shot.
