Bug#675729: linphone-nox: SIP calls not working due to bug with STUN

[Ubuntu6226]

Package: linphone-nox
Version: 3.3.2-1
Severity: important

Hi,

I'm in a local network behind a router which is connected to the
internet via DSL.

In the settings, I entered a STUN server (stun.ekiga.net) and
selected the radio button before the server text field. I can see
the change in Linphone's configuration file at ~/.gnome2/linphone.
Both audio input and output are directed to/from my USB headset,
and I can play the ringtones in the settings locally. I have
unselected the video transmission. I've set the upload and
download bandwidth to 300 kBit/s, thus all codecs are enabled.

When calling the echo test account at sip:500 at xxxxxxxxx , I hear
nothing though the echo test call works fine with both Ekiga
and Twinkle: I can listen to the remote voice and my own when
it's echoed back, but as said, not in Linphone.

By analyzing the network traffic with tcpdump and Wireshark, I
saw that Linphone actually queries the STUN server and gets a
response containing the public IP address. However, when sending
the SIP INVITE message to the server at ekiga.net, it includes
only the local address, not the public address. Consequently, I
see in the network traffic dump that RTP packets are sent to the
remote host but that I get no RTP packets back.

Specifying the public IP address manually in Linphone's settings,
attempting a workaround, doesn't work either.

Do you have any ideas to get STUN effectively to work in my
network/Linphone configuration?

Another question: Is there a bug tracker for Linphone? (As I
understood the website, there's none - bug reports should go to
this mailing list. Is this correct?)

Yours sincerely,
