Hello again, I can not figure oneself, tha Yours modem has "symetric NAT", but all is possible ...
Try this: - set the modem to defaults - no port forwarding, no firewall holes, ... [if STUN is working <OR> SIP proxy is used, You should do not need them] - install Twinkle - get a sip account at iptel.org try to call "music" and "echo" with this account It should work, even if twinkle sends as his RTP contact local IP and port. [this is iptel.org workaround - this SIP server ignores RTP contact send by client a sends audio streem out to that ip/port, from where it gets streem in (I thing so)] To call someone else (not on iptel.org), You have to set STUN server (e.g. stun.iptel.org) in Your profile settings -> Transport/NAT or set sip.iptel.org in Your profile settings -> SIP server If I remember good, then this proxy acts also as RTP proxy and this should help even in case of "symetric NAT", I thing ... Try it and report :-) --kapetr ----- PŮVODNÍ ZPRÁVA ----- > Date: Thu, 25 Feb 2010 21:24:52 +1100 > From: mat101 <matthews...@netspace.net.au> > To: Ekiga mailing list <ekiga-list@gnome.org> > Subject: Re: [Ekiga-list] Ekiga on Ubuntu using DSL > 302G D-Link modem > Message-ID: <4b864ff4.10...@netspace.net.au> > Content-Type: text/plain; charset="iso-8859-1"; Format="flowed" > > kapetr wrote: > > 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 !!!
