Re: [Ekiga-list] Ekiga on Ubuntu using DSL 302G D-Link modem

["kapetr" <kapetr mizera cz>]

The reason, why You can't communicate with Ekiga behind Yours D-link
is simple.

EKIGA IS BUGGY

I have report this Bug many times in many places.
I have also try to contact the author of Ekiga.

Unfortunately - I have get NO replay anytime !!!

The problem with Ekiga is, IT DO NOT WORK BEHIND NAT.

The use of STUN is broken:

Ekiga makes STUN request, but in INVITE (SDP section) send only discovered
public IP address, but the Port for RTM sends to the other side as the
local one, not that is reported by STUN replay !!

You can check it in wireshark - see the SIP INVITE packet.

I can NOT understand, how such significant Bug is ignored by developers
of Ekiga !!! And especially, why have I get no replays from them :-(

I can recommend You to use other client - Twinkle works fine.
