I have done some experimenting with ekiga with debugging, but have not
got much further. {Apologies for wrap-around from this mailer in the
debug messages below.}
2007/01/04 22:56:58.748 0:05.734 ekiga Set TCP
port range to 30000:30010
2007/01/04 22:56:58.798 0:05.792 ekiga Set RTP
port range to 5010:5059
2007/01/04 22:56:58.863 0:05.849 ekiga Set UDP
port range to 5062:5100
The above look ok. My main router has no logged any relevant blocked
packets. The ATA only exposes its SIP (set to 5060) and RTP (set to
5004) ports. I am now wondering about 30000:30010...
The "magic" manipulation of the Network setting was logged as

STUN server "stun.ekiga.net" replies Cone NAT, external IP 86.3.137.146
A failed call without that "magic" has debug entries like:

I am not sure if the above messages suggest blocked ports: I guess that
fits the failure to create the sockets. Since they are RTP sockets and
those are open, I am not clear what is happening.
I can live with the present situation, but would like to understand what
is failing. But it is not urgent.
