I got my GXV-3000's
And unfortunately it does not work with Gizmo5 Sad

This is what works.
1) 2 Grandstream's GXV-3000 IP phones connected to the sipphone network
2) GXV-3000 with CounterPath's Eyebeam (not X-lite).

I also test
CounterPath's Eyebeam with Gizmo5 and it did not work.
i
The main problem is when the initial call (voice) is stablished between GXV-3000/Eyebean and Gizmo then Gizmo does not enable the "camera icon" to send the video (it did not received too).

Other thing I did not like about the GXV-3000 is the lack of iLBC codec for voice...

Hope this info helps somebody.
