Setzt man den Intertex IX67 mit einem SNOM Softphone oder aber mit SNOM 190/360 mit einer Firmware >= 3.57 ein (also auch bei der Firmware 3.60), so muss man derzeit entweder das Security Profile des IX67 auf "low" stellen oder aber im Security Profile "high" den port 3478 (UDP) (Security settings -> Applications from inside -> Other UDP ports) eintragen.
Hintergrund:
The problem is with the snom phone. It does not send a 200 OK to the INVITE. In "low" STUN is allowed by default, but not in "high". I guess the Snom phone cannot cope with situations where STUN does not work.
