I just tested ekiga with a friend. He use not ekiga, but a other sip-software. Everything seems to work, but if he is calling me, he can't hear me, but I can hear him. The other way round, if I call him, everything is fine.
Have somebody the same problems?? My Router (NAT) is configured well. I have test several other settings, but no one works. And ekiga says, that everything is just fine configured, I use "STUN" as "NAT Traversal Method" with the stun.ekiga.net server. "IP Translation" or "None" doesn't work, too.
For a test call, you can call me at: sip:firstname.lastname@example.org
