I can make calls, at least it rings, from a notebook to a desktop pc,
but not in the other direction.

The notebook uses Opensuse 11.3, the desktop pc Xubuntu 10.10

The notebook is connceted to a mifi-modem via WLAN, which is connected
via UMTS. The desktop PC is connected to a server (opensuse 11.3),
which is connected to a DSL-Modem (Fritzox). The UMTS-Provider is Yesss
in Austria. VoIP works with Yesss generally.

with Opensuse 11.3 this used:
linphone-applet-3.3.2-1.pm.4.3.x86_64
linphone-msx264-1.3.3-0.pm.2.3.x86_64
linphone-3.3.2-1.pm.4.3.x86_64

On Xubuntu 10.10:
linphonec --version
version: 3.3.2


Open ports in Suse-Firewall and Fritzbox
TCP-Ports: 1720
UDP-Ports: 3478:3479, 5000:5059, 5061:5100, 7077, 8000:8010, 9078

Firewall deactivated with Mifi-Modem (Huawei E585)

Used ports with linphone:
SIP 5061 UDP (5060 is reserved by the Fritzbox)
Audio 7077 UDP (7078,7079 is reserved by the Fritzbox)
Video 9078 UDP

stun: stunserver.org

actually usernames are replaced by nοtebοοk and desκtοppc

From nοtebοοk to desκtοppc it rings and I can see video from both
sides. Since I was alone when testing, I could not test audio.

"Presence messaging" did _not_ work, but is activated.

From the debug-log:
