Klaus,

I had the same kind of issue with another 3G GW and another SIP phone (Kapanga). The trick was that the SIP phone was configured not to display the video stream until the first I frame was presented. What happend is that the handset at the other end would send only an I frame once at the beginning of the call and would not resend any. However this first I frame was missing or incomplete so video was not displayed.

So check if there is such a configuration on eyebeam and disable it.
